  • Distorted choppy audio in Precise

    - by Misery
    After installing Precise on my PC, some problems with soud occure. While using Lucid there were no problems. The sound is choppy and distorted in low tones range. As I absolutely have no experience in setting/testing and doing anything with Audo Devices I need help even to diagnose the problem. update: sudo lshw -c multimedia *-multimedia description: Audio device product: Radeon X1200 Series Audio Controller vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 5.2 bus info: pci@0000:01:05.2 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi bus_master cap_list configuration: driver=snd_hda_intel latency=32 resources: irq:19 memory:fdafc000-fdafffff *-multimedia description: Audio device product: SBx00 Azalia (Intel HDA) vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 14.2 bus info: pci@0000:00:14.2 version: 00 width: 64 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: driver=snd_hda_intel latency=32 resources: irq:16 memory:fe024000-fe027fff update 2: It has something to do with the volume. If the audio is quiet it is not choppy, if the sound is loud then it begins to be choppy. Regards, Misery

  • Audio not working in 12.10

    - by frampy
    I did a clean install of 12.10, when I open Sound Settings in gnome the only device in the list is "Dummy Output", and sound is not working. Sound worked fine out of the box in 12.04 I ran alsamixer, it says my card is "HDA Intel", and chip is "Realtek ALC880". The alsamixer playback output was set to mute at first, unmuting did not fix. I checked out the info at http://www.unixmen.com/2012003-howto-resolve-nosound-problem-on-ubuntu/ as suggested on a similar question, I've done everything there except installing the ubuntu audio dev team driver. Should I try install this? Edit: I've been reading the sound troubleshooting guide at https://help.ubuntu.com/community/SoundTroubleshooting It looks like Ubuntu is finding my audio device correctly. mike@wucade:~$ lspci -v | grep -A7 -i "audio" 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) Subsystem: Albatron Corp.

  • Synced audio ouput on multiple machines? VLC? hardware solutions?

    - by zimmer62
    I'm wondering if there is any software or hardware solutions to synced audio or audio and video across multiple computers or devices on a network. I've seen Sonos, and it might be a good solution, but it's also a very expensive solution. I'd like to be able to play something with realtime audio output on one PC, but hear it on speakers throughout the house, being it the home theater receiver, or another computer in another room. I saw a solution using the apple iport express, but the latency was unacceptable for anything other than just music. I'd like to avoid running audio wires with baluns to a bunch of amplifiers scattered all over the place when I have cat5 run everywhere. Is anyone familiar with using this kind of process for whole home audio? The latency is a big deal for me, if I've got video attached to the sound (e.g. watching a hockey game)

  • Audio tag doesn't work in FF-Ubuntu 12.04

    - by Nyx
    Does anyone know why this code... <audio width="0" height="0" autoplay="autoplay" loop="loop" preload="none"> <source src="images/musica/Intro.ogg" type="audio/ogg" /> <source src="images/musica/Intro.mp3" type="audio/mpeg" /> </audio> ...works fine in FF17-WinXP and not in FF17-Ubuntu 12.04? I think something is wrong with MIME types but everything looks normal. After searching on the web for days I couldn't find a good answer. Thanks

  • How to play multiple audio sources simultaneously in Silverlight

    - by Shurup
    I want to play simultaneous multiply audio sources in Silverlight. So I've created a prototype in Silverlight 4 that should play a two mp3 files containing the same ticks sound with an intervall 1 second. So these files must be sounded as one sound if they will be played together with any whole second offsets (0 and 1, 0 and 2, 1 and 1 seconds, etc.) I my prototype I use two MediaElement (me and me2) objects. DateTime startTime; private void Play_Clicked(object sender, RoutedEventArgs e) { me.SetSource(new FileStream(file1), FileMode.Open))); me2.SetSource(new FileStream(file2), FileMode.Open))); var timer = new DispatcherTimer { Interval = TimeSpan.FromMilliseconds(1) }; timer.Tick += RefreshData; timer.Start(); } First file should be played at 00:00 sec. and the second in 00:02 second. void RefreshData(object sender, EventArgs e) { if(me.CurrentState != MediaElementState.Playing) { startTime = DateTime.Now; me.Play(); return; } var elapsed = DateTime.Now - startTime; if(me2.CurrentState != MediaElementState.Playing && elapsed >= TimeSpan.FromSeconds(2)) { me2.Play(); ((DispatcherTimer)sender).Stop(); } } The tracks played every time different and not simultaneous as they should (as one sound). Addition: I've tested a code from the Bobby's answer. private void Play_Clicked(object sender, RoutedEventArgs e) { me.SetSource(new FileStream(file1), FileMode.Open))); me2.SetSource(new FileStream(file2), FileMode.Open))); // This code plays well enough. // me.Play(); // me2.Play(); // But adding the 2 second offset using the timer, // they play no simultaneous. var timer = new DispatcherTimer { Interval = TimeSpan.FromSeconds(2) }; timer.Tick += (source, arg) => { me2.Play(); ((DispatcherTimer)source).Stop(); }; timer.Start(); } Is it possible to play them together using only one MediaElement or any implementation of MediaStreamSource that can play multiply sources?

  • How can I stream audio signals from various devices/computers to my home server?

    - by Breakthrough
    I currently have a headless home server set up (running Ubuntu 12.04 server edition) running a simple Apache HTTP server. The server is near an audio receiver, which controls a set of indoor and outdoor speakers in my home. Recently, my father purchased a Bluetooth adapter, which our various laptops and cellphones can connect to, outputting the music to the speakers. I was hoping to find a solution that worked over Wi-Fi, namely because it won't cost anything (I already have a server with an audio card), and it doesn't depend on Bluetooth. Is there any cross-platform (preferably free and open-source) solution that I can use which will allow me to stream audio to my home server, over my home network, from a wide variety of devices (laptops running Windows/Linux or cellphones running Android/BB/iOS)? I need something that works at least with Windows and Android. Also, just to clairfy, I want something that simply allows devices to connect to my server and output an audio signal without any action on the server end (since it's a server hidden away near my receiver). Any subsequent connection attempt should be dropped, so only one device can be in control of the stereo at once.

  • Help with dynamic range compression function (audio)

    - by MusiGenesis
    I am writing a C# function for doing dynamic range compression (an audio effect that basically squashes transient peaks and amplifies everything else to produce an overall louder sound). I have written a function that does this (I think): public static void Compress(ref short[] input, double thresholdDb, double ratio) { double maxDb = thresholdDb - (thresholdDb / ratio); double maxGain = Math.Pow(10, -maxDb / 20.0); for (int i = 0; i < input.Length; i += 2) { // convert sample values to ABS gain and store original signs int signL = input[i] < 0 ? -1 : 1; double valL = (double)input[i] / 32768.0; if (valL < 0.0) { valL = -valL; } int signR = input[i + 1] < 0 ? -1 : 1; double valR = (double)input[i + 1] / 32768.0; if (valR < 0.0) { valR = -valR; } // calculate mono value and compress double val = (valL + valR) * 0.5; double posDb = -Math.Log10(val) * 20.0; if (posDb < thresholdDb) { posDb = thresholdDb - ((thresholdDb - posDb) / ratio); } // measure L and R sample values relative to mono value double multL = valL / val; double multR = valR / val; // convert compressed db value to gain and amplify val = Math.Pow(10, -posDb / 20.0); val = val / maxGain; // re-calculate L and R gain values relative to compressed/amplified // mono value valL = val * multL; valR = val * multR; double lim = 1.5; // determined by experimentation, with the goal // being that the lines below should never (or rarely) be hit if (valL > lim) { valL = lim; } if (valR > lim) { valR = lim; } double maxval = 32000.0 / lim; // convert gain values back to sample values input[i] = (short)(valL * maxval); input[i] *= (short)signL; input[i + 1] = (short)(valR * maxval); input[i + 1] *= (short)signR; } } and I am calling it with threshold values between 10.0 db and 30.0 db and ratios between 1.5 and 4.0. This function definitely produces a louder overall sound, but with an unacceptable level of distortion, even at low threshold values and low ratios. Can anybody see anything wrong with this function? Am I handling the stereo aspect correctly (the function assumes stereo input)? As I (dimly) understand things, I don't want to compress the two channels separately, so my code is attempting to compress a "virtual" mono sample value and then apply the same degree of compression to the L and R sample value separately. Not sure I'm doing it right, however. I think part of the problem may the "hard knee" of my function, which kicks in the compression abruptly when the threshold is crossed. I think I may need to use a "soft knee" like this: Can anybody suggest a modification to my function to produce the soft knee curve?

  • Why does 3.5 mm audio out work through headphones but not through external speakers?

    - by Rickster
    I have a computer that has a 3.5 mm audio jack on the front of it. The computer itself has no speakers, so this is the only way to hear sound. If I plug headphones into it, the audio properly plays through the headphones, and if I plug in external speakers it used to play through them as well. Just today I turned on my computer and the audio no longer plays through the speakers, but if I plug in the headphones instead it works. The speakers aren't broken, as both the speakers and headphones work in my iPod and play music. I thought that 3.5 mm jacks could not send data back to the computer, and the computer had no way of differentiating between different devices plugged into the jack. If this is true, how is it that the computer plays audio through the headphones but not through speakers plugged into the same 3.5 mm jack, and both devices are functional? Or is my knowledge on 3.5 mm jacks incorrect? I don't believe drivers are important, as the same driver runs the 3.5 mm jack for all devices, but if necessary I can provide additional information. Any ideas would be appreciated. Thanks!

  • How can I stop Ubuntu from playing audio from 2 interfaces at the same time?

    - by Solignis
    Hi there, I just loaded Ubuntu 10.10 Maverick on my home machine. The machine is running a Core2Duo E6750 on an MSI motherboard with an Nvidia GTX260-OC Graphics card. The problem I am having as stated in the title is for some reason Ubuntu is playing audio through my headphone coming out from the computer and it is also playing the audio at the exact same time through the HDMI connection coming out of the graphics card, it has a plug to allow this. What is going on, I have never seen this before. Most importantly of all can it be fixed so that I can sepertate the 2 interfaces, the one is a standard PC audio IO and the HDMI one is connected through the mobo's internal SPDIF. More information can be provided if required.

  • Can I reprogram a microphone input to be used as an audio output? (on XP)

    - by qftme
    I have a five year old Sony Vaio laptop (vgn-fw31m) that has had impact damage to the audio-output mini-jack for about the last year or so. In a recent discussion with my brother, we wondered whether it would be possible to write a program that would enable windows to use the microphone mini-jack input as the audio-output? As I currently use this laptop for work I am not keen to risk pulling it apart in order to replace the components comprising the audio-out. I therefore 'hope' that a programming solution exists. I would really appreciate any advice on this and eagerly await your response. Kind regards, qftme :)

  • Order by text and then by number

    - by Chaim Chaikin
    I have data like: Audio 1 File 10 Audio 2 Audio 3 File 11 Audio 13 Audio 22 File 20 Test 22 Audio 10 File 1 File 2 I need it order first by the text (i.e. Audio, File, Test) and then by number (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22 etc.) The problem is that sorting it returns something like this: Audio 1 Audio 10 Audio 13 Audio 2 Audio 22 Audio 3 File 1 File 10 File 11 File 2 File 20 Test 22 While the result I want is: Audio 1 Audio 2 Audio 3 Audio 10 Audio 13 Audio 22 File 1 File 2 File 10 File 11 File 20 Test 22 If they were just numbers (i.e. without the audio, file, test) then I could just sort numerically. However, how can I sort here first by text and then by number.

  • Apache 301 redirection from one domain to another

    - by Sebastien Lachance
    I'm trying to set a redirection in my VirtualHost configuration for my website. So far I am able to redirect non www trafficto the www address like this : <VirtualHost: *:80> ServerAlias www.gcbeauce.com RewriteEngine on RewriteCond %{HTTP_HOST} ^guidedescommercesdebeauce\.com$ [NC] RewriteRule ^(.*)$ http://www.guidedescommercesdebeauce.com$1 [R=301,L] But what I also want is to redirect the old domain to this new one. I have tried adding : RewriteEngine on RewriteCond %{HTTP_HOST} ^guidedescommercesdebeauce\.com$ [NC] RewriteCond %{HTTP_HOST} ^gcbeauce\.com$ [NC] RewriteRule ^(.*)$ http://www.guidedescommercesdebeauce.com$1 [R=301,L] But nothing happens. Am I missing something here?

  • IIS 6 nested virtual directory redirection

    - by threedaysatsea
    We're running IIS 6 on a WinServer2k3 box and we're having some trouble with the following problem: E-mails were sent out to users asking them to go to the following URL: alias.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue However, the URLS are actually supposed to be: server.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue It's too late to recall all of the e-mails, and we'd like to redirect traffic to make this as seamless as possible for our users. The real problem here is that the server (server.contoso.com) is hosting the alias (alias.contoso.com) as a redirect thusly, and the existing redirect we need to keep functional: Default Web Site (server.contoso.com) --Directory1 --Directory2 --Directory3 Redirection to Directory3 (alias.contoso.com) --Essentially alias.contoso.com will take the user to server.contoso.com/Directory3 Is there any way to host a separate redirect inside of the existing redirect? We need to keep alias.contoso.com taking the user to server.contoso.com/Directory3 but also make alias.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue point to server.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue Any tips? Is this even possible?

  • How to configure my hosting provider for email when DNS redirection already in place?

    - by Johann
    First of all I apologize for my poor understanding of network and I hope I used the correct terminology for everything: I have bought a domain name with 1&1 to create an online shop, using kingeshop. I followed the steps explains here to point the domain name to kingeshop IP address and everything is working fine. Now I would also like to use my domain name to create an email account. But 1&1 seems to say they're not responsible for this now the DNS is transfered to kingeshop's. What I'm wondering is who is really "in charge" of my domain name now? 1&1 also lets me configure the MX-record but I don't have a clue what I can do with this. Could I just use an existing gmail address somehow? Thanks a lot for any help or clarity you can bring me on that matter!

  • Do browsers change URLs of saved bookmarks in response to 301 redirection?

    - by elliot100
    HTTP status code 301 is used to indicate that content has moved permanently, and that the returned URL should be used to access the requested content in future. RFC 2616 says Clients with link editing capabilities ought to automatically re-link references to the request-URI to one or more of the new references returned by the server, where possible. Do any browsers actually implement this and change a bookmark's URL?

  • Can I set up arbitrary filesystem redirection in Windows?

    - by Jon
    I am sitting in front of a Windows 7 machine that has no drive Q:. Is it possible to arrange for accesses to Q:\somedir to be redirected to an arbitrary location on the existing filesystems (for example, C:\Windows)? I would especially like a "set it and forget it" option, if one exists. I am assuming (although I have not tried it) that it is possible to use SUBST to mount an existing (empty, created for this purpose) folder as drive Q: and then MKLINK /J to create a directory symbolic link from Q:\somedir to wherever I want. However, this approach has a couple of drawbacks that I would like to avoid if possible: The drive Q: will be visible in the system. It is not as clean as I would like (removing the mounted folder will break it; a batch script needs to be manually added to the system startup). Is there a better option? If there is none and I am forced to make compromises, what is the closest I could get to the ideal solution? Assume anything is up for discussion.

  • KDE: How can I select audio output device for mplayer?

    - by grimripper
    I recently installed Kubuntu 13.10 64-bit, and I'm having a problem with selecting audio output device. In Phonon, when I select audio device preference order and press Apply, Amarok and Dragon will immediately switch to the preferred device. VLC and SMplayer are not affected. VLC has its own setting for selecting the output device, but SMplayer remains a problem. It always plays audio on internal audio, and I can't change output to HDMI. How can I select HDMI for SMplayer's audio output device? I don't know if it matters, but when I select HDMI audio in Phonon and click Test, the test sound plays on the internal audio output as well. In the hardware settings tab, the front left and front right test buttons play audio on HDMI. Also, volume up/down buttons affect HDMI volume when SMplayer is focused. This would make sense if I could get SMplayer to play audio over HDMI, but it would be better if the volume keys affected SMplayer's own volume, or the "mplayer2: audio stream" which appears in volume control while mplayer is playing. EDIT: I've recompiled mplayer with alsa support, and can now select the audio output device from SMplayer's settings. Didn't affect the issue with Phonon of course, but it's a suitable workaround.

  • AVAudioRecorder - Continue recording to file after user stops recording by leaving the application a

    - by Tegeril
    Can this be done? And if not, how far down towards Core Audio do I need to go (what method of recording should I be using instead)? I've noticed the behavior of AVAudioRecorder is to overwrite a file if it finds one at the path provided when you request that it record again, so I know that's not going to work. I'm also curious about file format restriction with this idea. Can you effectively resume an AAC or IMA4 encoding (the length of the files I want to record make WAV and probably even Apple Lossless prohibitive)? Thanks.

  • Streaming Audio over UDP to Android

    - by Mr. Pig
    Is it possible to have Android (perhaps via MediaPlayer or a different existing class) accept media streams over UDP? I've successfully had MediaPlayer connect to an HTTP stream (as well as static files hosted on an HTTP server) but I'm wondering how one would go about accepting a stream from a UDP source. I've seen this and suppose a solution similar to that (where I download the stream via an independent UDP socket and then move the data to a MemoryBuffer that I then pass to MediaPlayer) is an option but I'm curious if a method already exists in the SDK, and if it does not, what other options do I have? Thanks
