Ubuntu 12.04 audio problems
Posted: Mon Jan 07, 2013 9:38 pm
Tested on two Intense PC entry models, to rule out hardware problems. I started by installing Ubuntu 12.04, ran system update (to 12.04.1).
There is just one audio output, "Digital Output (S/PDIF) Built-in Audio" (photo attached).
Audio doesn't work. If I pull the audio connector out and hold it at just the right spot, I can hear sound that's quiet and it's very distorted. Oddly, if I turn the volume down (while holding the connector at just the right spot), the audio gets less distorted but is still really quiet.
If I plug in a USB audio speaker, audio works perfectly fine.
The output of aplay -l (without the USB audio speaker plugged in) is:
I tried updating to the latest kernel, 3.6.5, which had the same problem as 3.2.0-30 (the 12.04.1 kernel). 3.6.5 would not reboot successfully for me, so I removed it.
Any suggestions? Is there no headphone level output on the IPC?
