Could you post the output from this script: http://bulletproof.servebeer.com/alsa/scripts/alsa-info.sh

It was written by a user on the #alsa irc channel, and has been very helpful in debugging sound driver issues, at least for me.

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?
