12.10

I installed the 12.10 yesterday and like 12.04 there was no sound, I have an ACER 4830 TG. I noticed that the HDMI output is working fine, but Speaker or Headphone isn't working.

So I did the following:

sudo add-apt-repository ppa:ubuntu-audio-dev
sudo apt-get update
sudo apt-get dist-upgrade

and still couldn't get the sound.

Then I found the temp fix for this issue which is to Suspend the machine completely and resume. However, after restart the same thing happens.

Is there a solution to this issue?

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
