Description of problem:
I had an installation of Redhat earlier (9, I think) last year that
gave me this same error. My sound device is identified SiS PCI Audio
However, the mixer settings are gone. This happened after I switched
from Gnome to KDE and back again. I loaded two daemons: lisa and smb.
Removing them has not fixed the error. According to the Soundcard
Detection, I have a sound device. However, the system is unable to
open /dev/mixer.I have located the file. It is a zero-length
character-device file with read/write permissions. I've also located a
second file "mixer1" that is apparently the same.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
4.Switch to KDE
5. Enjoy Linux
6. Switch back to Gnome
7. Hate Linux
8. Go back to Windows
This is the reason I dropped Redhat in the first place. Ironically,
and I really hate to say this, I've never had any problems on this
machine with the sound OR the video driver with Windows.
When you say the "mixer settings are gone" do you mean that the panel
volume control has disappeared or have you lost the ability to play
sound at all?
Yeah, sorry about the attitude. No music can make a guy cranky. What
happened was I lost sound altogether. Somehow in changing desktops
from Gnome to KDE (I have better luck Samba-ing) with KDE, the mixer
settings file got moved or deleted. I noticed that come up during
shut-down. Hence, I had no sound because the mixer didn't know what
to do. I rebooted normally with KDE as the default. It came up. My
sound was back. But I don't have a speaker icon. Is that supposed to
be in KDE? Can't remember. I haven't been in Gnome for a while. I'll
see what happens when I switch back.
I do not believe that KDE has the volume control in the panel by
default. Please reopen this bug if the volume control has disappeared
from the Gnome panel.
