ALsa and Logitech quickcam pro 9000

All,
Thanks for reading.

Only if I reboot Slackware 12.1 without my webcam, I get sound. If I do otherwise my webcam becomes the default sound device.

Apparently I have to load the modules in the right order. What is the best way to do this permanent?

Here is some output.

Make sure that /etc/modprobe.d/alsa (or /etc/modprobe.conf, or whatever file contains your sound driver configuration) has the following lines:

Code:

alias snd-card-0 snd-intel8x0

alias snd-card-1 snd-usb-audio

options snd slots=snd-intel8x0,snd-usb-audio

This has never worked for me. The only way to force a soundcard to do that (in my experience) is to recompile the kernel with the preferred card built in (ie. not as a module).

The above example didn't work for me, alsa threw up multiple errors at boot time. If there is a way to do this without recompiling my kernel I would love to know!

Looks like the "slots" option is not recognised

I have also used this in the past:

Code:

alias snd-card-0 snd-intel8x0

alias sound-slot-0 snd-intel8x0

But still the cards swap at random...

Quote:

Code:

snd: Unknown parameter `slots'

This parameter exists since ALSA 1.0.16 or kernel 2.6.25.

Quote:

Code:

snd_timer: Unknown symbol snd_info_register

...

This indicates that the "snd" and the "snd-timer" modules have not been compiled for the same kernel (configuration). In most cases, this happens when you try to load a newly compiled module although some old sound module is still loaded.

With earlier driver versions, you have to set the "index" option for each sound driver, like this:

Code:

alias snd-card-0 snd-intel8x0

alias snd-card-1 snd-usb-audio

options snd-intel8x0 index=0

options snd-usb-audio index=1

Code:

tuttle@shangrila:~$ uname -r

2.6.24.5-smp

tuttle@shangrila:~$ ls /var/adm/packages/alsa-

alsa-lib-1.0.15-i486-1    alsa-oss-1.0.15-i486-1    alsa-utils-1.0.15-i486-3

Slack is so backward! ;)

Great info cladisch, many thanks.

Your solution worked cladisch, thanks for your time.
