bios update alters hda-intel and alsamixer

bios update alters hda-intel and alsamixer

[Chris Pemberton]

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

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.

Ok, according to what I can tell, you don't have the most recent version
of the driver (your original post didn't have an attachement).  I do
know that the Lenovo support for the ALC861VD was added after 1.0.14rc4
snapshot was made.

Try installing the most recent HG daily snapshot from
ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver .

If that doesn't fix it, rerun the alsa-info.sh script and repost the new
data.
