After updating the bios on a Lenovo notebook, my hda-intel sound "changed"
Before the bios update I used kernel 2.6.20.3, external alsa-driver-1.0.14rc3 and the attached patch_realtek.c (in-kernel alsa wouldn't work)
After the bios update I use just the alsa contained in kernel 2.6.20.3.
Before bios update, my mixer contained many items: including master, front, mic, pcm, etc.
Now it only contains master and pcm.
So, I have a few questions:
How can I determine what items are "supposed" to show up in alsamixer?
Where can I submit my laptop soundcard information to help finalize support of this model/card?
Thank you"
