Upgrades Lost Soundcard

[BoDiddley]

Hello all. I just did an update and upgrade a couple of hours ago, seemed like something major was going on - the kernel, and the kernel headers were included. Any way, when I rebooted Debian could not find my soundcard - literally.

I am dual boot - I did the obvious, checked Windows. Windows sound is fine.

Rolling-back an upgrade is new territory for me, Is this possible? I used "apt-get update", and "apt-get upgrade". I only do stable upgrades. I thought it might be easier to ask??? Any help would be appreciated.

By the way. I did try removing and reinstalling Alsa-base. Alsactl Init - did not return "soundcard not found" this time. But there is still no sound.

Back when I had my IBM 390E running Debian Testing repos and installing newer kernels. I found that the Debian developers had dropped .ko support in the kernel for some older soundchips like in my IBM 390E used.

This might be what you are experiencing. I would use lspci command to get the chip model of sound card and look to see if this was the case.

Even after the kernel upgrade. Grub should give you a choice to boot into the older kernel you still have installed where sound worked before also.

Thanks for the quick reply.

lspci shows sound card:

00:06.0 Multimedia audio controller: nVidia Corporation nForce3 Audio (rev a2)
00:06.1 Modem: nVidia Corporation nForce3 Audio (rev a2)
00:08.0 IDE interface: nVidia Corporation nForce3 IDE (rev a5)
00:0a.0 PCI bridge: nVidia Corporation nForce3 PCI Bridge (rev a2)
00:0b.0 PCI bridge: nVidia Corporation nForce3 AGP Bridge (rev a4)

Are you saying that I should check to see if support has been dropped for my specific card? Apparently the sound card is found.

Also considering dpkg-reconfigure on linux sound base to redefine alsa, not oss. I toyed with oss not long ago, but everything was fine until upgrades - I never actually installed oss.

Your computer is newer than mine was so no need to check on whether soundchip is supported.

More than likely something else gone south like you said like maybe config or something.

so first I guess try

lspci | grep Audio

just to be sure then

lsmod |grep snd

to see if it spits anything out or nothing at all.

I guess you can look through /var/log/dpkg.log to see what may have been uninstalled also during upgrade.

You could also poke around I guess with

cat alsa-base.conf

to see what it spits out also.
