No sound with 12.04.4 LTS

Asked by CanMan

Hello,

I previously had Ubuntu 12.04.4 installed; however after an update the sound wouldn't work I tried updating to 14.04 LTS, but I couldn't get that to run at all. After trying many things i just opted for a fresh installation of 12.04.4 LTS. but now i still have the same problem of no sound. I have sound coming out of the head phone jacks. I have the computer hooked up to a tv via a HDMI cable and i'm getting no sound through the TV.

I'm following this troubleshooting guide: https://help.ubuntu.com/community/SoundTroubleshootingProcedure i've gone through every thing on there twice without luck.

here are my result from step 3

Thanks!

If the problem is only with the Radeon HDMI audio, this the first thing I'd try: https://help.ubuntu.com/community/RadeonDriver#HDMI_Audio
If that did not work, I would try a newer kernel.

Can you help with this problem?
