Description of problem:
This may not be redhat-config-soundcard but its a good place to start :-)
I have a soundcard (Creative SB Live! - module emu10k1) and a USB audio device
(Philips camera - pwc module). redhat-config-soundcard both detected my emu10k
as part of firstboot and when run manually afterward. However, on both occasions
the "Play test sound" failed to play any sound. In addition, xmms with the OSS
plugin just sped through ogg files too quickly with no sound output.
/etc/modules.conf had been configured with two sound devices - sound-slot-0
pointed at the correct emu10k1 module and sound-slot-1 pointed at the "audio"
module. Both modules were loaded when I checked in normal operation.
When I "rmmod"'d the "audio" module and removed the sound-slot-1 config lines
from /etc/modules.conf, sound began to work again immediately. The test sound
played in redhat-config-soundcard and xmms played ogg files perfectly.
It appears that redhat-config-soundcard or other config program had set-up the
USB camera as sound-slot-1 device and this was being used as preferential output
Version-Release number of selected component (if applicable):
Didn't try (would require re-install)
Steps to Reproduce:
1. Installed on my system with noted hardware
2. Symptoms occurred
I have reports of this same thing occurring on Red Hat 7.3 with a soundcard and
USB camera with audio installed but I can't verify myself. Thus this may be a
Kudzu is actually doing the probing and configuring of modules.conf, so I'm
changing the component to that. One workaround might be to unplug the USB audio
device during installation.
Re-tried with Red Hat 8.0, got a clearer debug and re-bugged as id 75015.
