If webcam connected, then no audio

If I reboot my computer with my webcam (Logitech QuickCam Pro 9000) connected to the USB port, then there is no audio in Archlinux. Nothing can play, and alsamixer also says something like that the device has no playback.

If I reboot again with the webcam unplugged, the audio works again. If I connect the webcam only after booting, then the webcam works too, and the audio too.

The webcam happens to have a microphone built in, but I don't use that. I use a regular microphone and the soundcard integrated in the motherboard (which is quite good) for that.

So it seems as if something in (arch)linux appears to prefer using the webcam as sound card for audio OUTPUT, even though it's not made for that.

How can I make it so that I can leave the webcam connected to USB, *and* have it use my regular soundcard as sound device?

I don't really know a lot about how linux decides what the audio device is and how you can switch them by the way, any help or commands in that regard are welcome.

Thanks.

Re: If webcam connected, then no audio

On my machine I have the following in /etc/asound.conf

pcm.!default {
    type hw
    card XFi
}
ctl.!default {
    type hw           
    card XFi
}

Change XFi to whatever your builtin soundcard is called

Or you can blacklist whatever sound driver is loaded for the camera mic.
