Basically, sound comes out as a hissing, garbled mess *unless* I load down the CPU. A kernel compile seems to do nicely for this purpose.
I've been seeing this behavior in the late 2.6.0-pre kernels through 2.6.1 plain and -mm1. It happens with preempt and HPET both enabled and disabled. I haven't yet found what exact kernel version the problem starts with, and I get no sound with the OSS drivers, so I can't test them ATM. I plan to narrow things down if possible, but that takes time.
System is an Athlon at 1145 MHz on an ECS K7S5A (SiS 735 chipset) running Debian Sid with ALSA-base v0.9.8-3. The problem happens both with the onboard i810-compatible sound and a CM8738 PCI sound board. (Note that both are fixed at 48000 Hz.) I'm tempted to buy 'n' try a SoundBlaster-PCI card from FreeGeek.
I'd be happy to provide further info, but didn't want to start out with a super-long message for something that may be obvious, if not visible in Google or LKML. Please reply to the list; I'm subscribed.
