Hi, I've been having lots of problems with audio in Fedora 10. At first I was having problems playing sound in youtube via firefox. I found a tutorial which suggested I change a line in default.pa from: load-module module-hal-detect to load-module module-hal-detect tsched=0 That did seem to improve things. However amarok is really not happy. I can play mp3s for a minute or two but it is very crackly. Then eventually the audio stops and amarok locks up. /var/log/messages shows messages like this: Jan 8 21:26:46 localhost pulseaudio[3188]: main.c: High-priority scheduling enabled in configuration but not allowed by policy. Jan 8 21:26:46 localhost pulseaudio[3188]: core-util.c: setpriority(): Permission denied Jan 8 21:26:46 localhost pulseaudio[3191]: alsa-util.c: Device hw:0 doesn't support 2 channels, changed to 10.

Jan 8 21:33:29 localhost pulseaudio[3191]: cpulimit.c: Recevied request to terminate due to CPU overload. I've running an AMD Athlon 64 x2 (can't remember the exact model) although it's 32 bit Fedora 10. The soundcard is an M-Audio Audiophile 2496 (ICE1712 chip I believe). I never got pulseaudio working with this setup in Fedora 9 and had to remove all pulse packages. Now it's almost working but there are clearly still issues. Any ideas? (This is my home PC so I can only investigate in the evenings, UK time, so bear with me! ) Thanks, Chris.
