Description Christian Rose 2002-11-24 09:24:14 EST
Description of Problem:

I recently bought a Philips Toucam Pro web camera in order to use it with RHL
8.0 and GnomeMeeting. This camera is an USB device and has a built-in
microphone. It worked really well, I just had to plug it in and immediately
after that I had camera pictures in GnomeMeeting! Kickass. With a change in the
"Sound recorder" setting from the value "/dev/dsp" to "/dev/dsp1", my friends
could suddenly also hear me.

However, whenever I reboot, kudzu kicks in and appearantly wants to configure
the sound device in the camera if I still have it plugged in. No matter if I
choose "configure" or "ignore", after that all sound output on the machine is
non-functional -- it seems the default sound output device is then the camera(!)
instead of the sound card, although I'm not able to verify that theory. I have
to unplug the camera and re-plug it again to get sound back in my computer speakers.

Version-Release number of selected component (if applicable):

How Reproducible:

Every time.

Steps to Reproduce:

1. Plug in the Philips Toucam Pro camera in a running system. Note that computer
sound is still functional.
2. Reboot. Note that computer sounds (music, sound events) are now not functional.
3. Unplug the camera and immediately plug it in again. Note that computer sound
now becomes functional.

Actual Results:

Computer sounds (music, sound events) are silent/non-functional.

Expected Results:

Computer sounds (music, sound events) are hearable/playing.

May be related to bug 69945, bug 77178, bug 75015. It looks like kudzu us 
having a problem with USB audio devices and breaks the sound configuration on 
reboot. This includes webcams with an inbuilt microphone.

Closing out bugs on older, no longer supported, releases. Apologies
for any lack of response. Please reopen if problems persist on more
current releases.

This should be solved with the new hardware initialization in FC3.
