From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7a) Gecko/20040218 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 Accelerator. 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): How reproducible: Always Steps to Reproduce: 1.Install Linux 2.Run Linux 3.Enjoy Linux 4.Switch to KDE 5. Enjoy Linux 6. Switch back to Gnome 7. Hate Linux 8. Go back to Windows Additional info: 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.
