I sometimes have sound in Fedora 11 i386 about every eight or ten reboots sound will work. if I look in hwbrowser my sound device is listed, but in sound preferences the sound device is listed when sound works and "null output" is listed when it doesn't work.I tried removing pulse audio which did not help so I reinstalled it.
I had the same problem with fedora 10 i386 although sound worked 70% of the time if it did not work a reboot would usually fix it. The sound problem with Fedora 10 seemed to dissapear on its own .
Fedora 11 needs 8 or 10 reboots to get sound to work.
hwbrowser lists my sound card as:
VIA Technologies, inc. VT1708/A (azalia HDAC) (VIA high definition audio controller)
Any help with this would be greatly appreciated!
