wrong "audio" card found?

[Michael Hennebry]

After a recent reboot, I no longer have sound,
either with mplayer or with firefox.

mplayer "works" with -nosound .
I have a Radeon 3600 series video card.
I have AC97 sound that I think is built into the motherboard
(B865GBFL) and to which my speakers are attached.
Apparently the Radeon does audio.
lspci lists it twice, once for video and once for audio.
lspci also list AC97.
My suspicion is that mplayer and firefox are trying to use the Radeon..

How do I tell what they are trying to use?
How do I tell them to use AC97?

I hate it when things just don't work.

I've got what linux thinks are 3 audio devices.
The built in motherboard, the pci card I added to get
optical output, and a USB microphone in my webcam.

I had to add this /etc/modprobe.d/usbmic.conf file
to get everything assigned to consistent index
numbers no matter what order the devices get
enumerated:

alias snd-card-0 snd-hda-intel
options snd-hda-intel index=0
options and-card-0 index=0
alias snd-card-1 snd-ca0106
options snd-ca0106 index=1
options snd-card-1 index=1
alias snd-card-2 snd-usb-audio
options snd-usb-audio index=2
options and-card-2 index=2

With the pulseaudio sound dialog there is also
a hardware tab and you can select devices and
mark them not to be used by pulse (which I do
with the optical output card since I want to
dedicate it to alsa output from mplayer).

The following question is not directly relevant to my cause.
I'm trying to make speakers work.
How did you discover what you needed?

For me a likely suspect seems to be /etc/modprobe.d/also.conf ,
but I can't tell what it's pointing at:
# ALSA Sound Support
#
# We want to ensure that snd-seq is always loaded for those who want to
# use
# the sequencer interface, but we can't do this automatically through
# udev
# at the moment...so we have this rule (just for the moment).
#
# Remove the following line if you don't want the sequencer.

install snd-pcm /sbin/modprobe --ignore-install snd-pcm &&
/sbin/modprobe snd-seq

Is that just a gnome thing?
I'm running KDE.

I think I correlated dmesg output with the native
device number assignments shown by listing them with the
alsa utility programs, then played with the
modprobe file till they came out right. It has
been a long time since I created the file, and
I've just been copying it from release to release :-).

Don't know if it will only work in gnome, but the
tool is named gnome-volume-control. Goto hardware
tab and select profile "off" for the device you
want pule to ignore.

You mean the numbers I got with lspci?
What is the modprobe file?

I'll go looking when I get back to my home computer.

Nope. The alsa system assigns an index number to each audio
device, and things seem to go much better if the one that
should be the default is index 0. (Though if you use
pulse for everything it seems to do a better job
of sorting things out even if the index numbers change).

The /etc/modeprobe.d/usbmic.conf file for earlier post.

Thanks.  I have it.
It did the trick.
