[Sound] QuickCam Interefering with SoundBlaster Live! audio.

[Jamie Krasnoo <jkrasnoo@xxxxxxxxxxxx>]

Hi all,

I'm new to the list and have a slight problem. I'm not sure if this is
the right list to post this question to, so I apologize ahead if time.

I have a USB QuickCam Pro 3000. It registers fine but then it interferes
with the audio of the soundblaster card. 

Here is a sample of the dmesg with the extra 'dma time outs' removed.

And the problem was solved when I removed the QuickCam from the USB Hub.

Audio still works until I reboot and then the camera interferes with the
audio again. Seems like the microphone is screwing things up. I would
appreciate if anyone has a solution to this, like something I have to
put in to the modules.conf so that the microphone doesn't try to barge
in on any of the soundblaster's settings.

Thank you,

Jamie
