Hmm ... Just tried kernel 2.6.38 from debian sid, and Microphone is not working again. However, this fix is in. What might have broken it this time? I hope to find some time to track down the commit somewhen the next days ...
Wolfgang,
When I was fighting with Mic issue, I used hda-analyser script. Try it and check how the pin 0x1e (Front Mic) is configured. My symptom was that this pin has been initiated with VREF Hi-Z. If you see that, try changing it to VREF 50. Mic should start working.
Oh - didn't know that. Impressive Script.
And just found out this time it was was propably false alarm.
All that happened is that both input sources got set to front mic when booting this kernel, and after selecting the correct (rear) source in the mixer things work.
