(Get the code!)
I've installed yesterday karmic koala alpha 4 in my inspiron 9400 (same as #7) and the audio isn't working correctly.
The behaviour is the same of #6.
The volume is too high. If I try to reduce it silence...
In pulseaudio volume controller the harware device is setted to analog stereo output (digital stereo duplex doesn't reproduce any sound).
If I launch from shell the alsamixer, i see that my sigmatel has a PCM, Master and LFE and that PCM is setted to 100%, LFE also and Master is about 15%. If I try to reduce one of this volume I see that they are related in the same order of phenest (first PCM, then LFE and only when they are at 100% the Master start to increase but obviously the volume is now too high and disturbed).
