Comment 20 for bug 582199

Also; I assume that playback and recording appears - from the computer side - to be working - but only silence is recorded and only silence is heard, right?

Anyway; here's what it looks like you need to do to get some playback (if we're lucky! This is likely a new model and might require additional code) :
1) Download and start hda-analyzer, see http://www.alsa-project.org/main/index.php/HDA_Analyzer
2) Go to pin 0x1A (should be "headphone out"), and make sure the mixer 0x0C is active in the connection list.
3) Go to pin 0x1B (should be "line out"), and make sure the mixer 0x0C is active in the connection list.

Close hda-analyzer and retry playback. The first one of you who does this (and has Dell Optiplex 380, of course!), please report back whether it worked or not, and regardless of whether it worked or not, also run "apport-collect 582199".

Assuming this works, we can then go on trying to get the mic up and running as well, and then try to get the new feature into the Linux kernel.

Thanks in advance.
