View Full Version : Sound suddenly stopped working

9th August 2008, 12:52 AM
I'm running Fedora 8 x86_64 ( with onboard sound Audio Chipset ADI AD1988B, Audio Channels 8 with Logitech X-540 70W 5.1 Surround Sound Speakers.

I hooked them up a few days ago with no problems. Everything is working fine. Then today a game (Assault Cube) froze and I rebooted then the sound stopped working.

If I go to System->Administration->Soundcard Detection and test the sound using AD198x Analog as the PCM device I can hear music. If I change it to AD198x Digital I hear nothing. XMMS doesn't play sound unless I switch it to OSS Driver.

PulseAudio, g-streamer and ALSA is all installed. Like I said everything has been working perfectly until the game froze.

Any thoughts?

I've tried a few things for other posts I've seen and its still not working. This is pretty odd.

How long do you have with that kernel? Did you install it about the same time the game?

Just today I had to switch over to F8 x86 because in F8 x86_64 that very kernel gave me some problems. Try booting in the other kernel (previous) to see if your problem persists.

I've had this kernel for awhile now without any problems and the game for the last three kernels. The sound is dead on everything not just the game.

Also I had this kernel when I setup everything so its been working. Its probably not related to the game thats just what happened at the time.

Same problem with the previous kernel and under different users, tested earlier today.

so have you tried disabling Pulseaudio? an just using Alsa only?

Have you looked in, by going to

System > Administration > Hardware > i think

Sessions > Startup Tab

Well, I uninstalled PulseAudio along with a few other things and that didn't seem to make a difference. I also made some changes to a few config files. With out any differences.

HOWEVER, System->Preferences->Sound I changed all playback to OSS driver and now I have sound for everything.
