Description Need Real Name 2001-11-09 16:55:59 UTC
Description of Problem: After 7.2 boots, the only sound service available is my usb microphone (on my Logitech QuickCam 3000). My Creative Labs Live soundcard is not shown in any of the mixers. I have to '/sbin/rmmod audio' to get my soundcard to work. Once I do that the sound card will be shown in the mixer and the usb audio module will *magically* reload and be in the mixer too. Version-Release number of selected component (if applicable): hotplug-2001_04_24-11 How Reproducible: Just boot 7.2 with a usb microphone (say on a webcam) and a Sound Blaster sound card installed. Steps to Reproduce: 1. Boot Red Hat 7.2 2. Open any mixer (i.e. gmix), see that USB Class Audio is only device 3. su to root, /sbin/rmmod audio 4. See that Creative Labs Sound Blaster Live and USB Class Audio devices are both shown in mixer. 5. I can now play MP3's Actual Results: I could (after completing the steps) properly use my soundcard. Expected Results: The usb audio module should not be loaded first or in a fashion that blocks the more crucial emu10k1 driver from working properly. Additional Information: I'll let the bug fixer ssh into my system if they want, so they can see what's going on.

I understand the problem, but can't think of a fix right know... for a workaround, you can put the driver in /etc/hotplug/blacklist

For me the problem is present, but just annoying. Both my scsi CDROM and my built in audio device change numbers if a USB device is plugged in at boot. USB devices must be recognized after motherboard devices, to keep things predictable.

"alias audio off" in modules.conf works well... anyway, I think this is more of an initscripts issue... soundcards must be initialized earlier, to avoid this.
Comment 4 Bill Nottingham 2002-04-11 19:21:41 UTC
initscripts does not initialize pci sound cards.
Comment 5 Bill Nottingham 2005-02-04 20:47:38 UTC
Closing out bugs on older, no longer supported, releases. Apologies for any lack of response. This is fixed in FC3 with the new hardware initialization on boot.
