Hi! I complained some time ago, several times, that 32kHz seems to produce oops on my onboard ECS K7S5A. It seems it isn't exactly 32kHz producing this, but buffer size combined with frequency. Because current cvs aviplay also manages to cause oops on 44.1kHz. Zdenek, aviplay maintainer, told me he shrunk the buffer size from 4 to 2 kB to obtain better interactive responsiveness.
So it seems ("educated guess") than some buffer offsets aren't calculated
correctly in intel8x0 (my sblive which I use as a second card has no such
problems), and produces buffer overflow when too small.
Becase I have received exactly 0 replies to all of my previous 3 emails, which
IMHO provided enough information, now I'll be a little bit harsher:
SOMEBODY BETTER FIX IT OR GIVE ME HINTS WHERE TO LOOK!
(hint: snd_intel8x0_setup_periods perhaps?)
I repeat: RH 7.1, kernel 2.4.18-pre4 with O(1), ide and preempt patches,
Duron900 (not overclocked), 192MB RAM, alsa 0.9.0beta10
Here are the damn oops-es:

After they happen, sound card remains silent and module blocked.
In the end I'd like to thank you all for your work, I remember when alsa was
in the beginnings, I used the special gus modules on my interwave clone to get
wavetable working. Your communicativeness seems to be lacking however, is it
REALLY that difficult to write "Hmm, sounds strange, I have no idea what could
be causing this, can you do more tests with xyz"?
Bye,
