I'm panicking... my sound stopped working after I tried to set-up my notebook speakers, plus two headphone jacks...
My idea was to multichannel the sound to 3 channels, built-in speakers, and sound-card 2 headphone jacks.
After a couple efforts I did it with 2 channels, speakers and 1 headphone jack, but the other wasn't working.
After more tries and tries, sound stop working.
I just want my sound back... crying like a baby on the floor.
And, if possible, but not necessary, a simple guide to active the 3 channels. xD
I will post the diagnosis according to https://help.ubuntu.com/community/SoundTroubleshootingProcedure
STEP 1
Did it, still no sound.
STEP 2
Did it, still no sound.
STEP 3 and #STEP 4

STEP 5
Rebooted, still no sound.
STEP 6
Did it.
In the Output Devices tab, nothing is muted.
I play a music with the Rhythmbox Music Player, I don't hear anything but in the pavucontrol I can see in the Built-in Audio Analog Stereo a sound bar shaking... but, no sound.
STEP 7
In alsamixer,
AlsaMixer v1.0.25
Card: HDA Intel PCH
Chip: Creative CA0132 information
View: F3:[Playback] F4: Capture F5: All
Item: Headphone [dB gain: 25.00, 25.00]
Then, I have 5 columns
Headphone, Speaker, PCM, S/PDIF, S/PDIF Default PCM
A little weird when I try to mute the Headphone and the Speaker, here what happens:
Starting both unmutted, mutting headphone cause speaker being mutted automaticaly.
Starting both unmutted, mutting speaker cause headphone being mutted automaticaly.
Starting both mutted, possible to unmute both separately.
STEP 8
I cannot hear sound on both (headphone and/or speaker).
STEP 9
Dual boot...
Restarted, windows was with sound at max volume.
Restarted again, still no sound at ubuntu.
I heard something when ubuntu started, a little noise, then silence again.
The sound icon always start mutted, after unmutting, I have no sound.
STEP 10
I dont have this command in my ubuntu.
STEP 11
Tried at STEP 8, no sound.
There are no problem with jumpers or hardware, cause I have sound working on windows.
STEP 12
No way to open my alienware and loss the warranty x.X"
STEP 13
I think it's loaded, judging my the logs
STEP 14
Alienware M17xR4, the hardware is listed in the logs above, at STEP 4.
There are two headphone hacks, one with just an headphone printed above, and the other with an headset (with mic) printed, there is a mic jack too, and a spdif (optical) too.
STEP 15
I dont want to enable S/PDIF
STEP 16
I never used the HDMI output, yet...
Thanks in advance.
I hope I listed all the information you need.
