OSS/ALSA issue

I don't know if this is true on any driver, but here's what happend yesterday: 
(i have au8810 driver; on x86_64 system)

i was watching google video on my system

(google video is a flash thing; thus emulated and uses OSS (the only app that 
needs it))

and suddenly gaim reconnected a network and beeped using aplay (ALSA)

as a result, the sound was played, all sound looped (also flash), and a few 
hours later, my /var/log/kernel/warnings was > 600MB (kernel warnings).


Now, we all know that:

1. ALSA has hardware mixing if the chipset/driver supports it (i know mine 
does).

2. OSS does not do any multiple sounds


so, the OSS application is continually using soundcard. and aplay plays a 
short one... should it work or must aplay be denied???

(i'm using latest alsa)

It should work.  ALSA's OSS emulation supports mixing if the card has
hardware mixing.  It is only in the case of software mixing that OSS
emulation cannot support multiple open.

Sounds like a driver bug.  What do the kernel warnings say?

It's a driver bug, please file a bug report if you can reproduce it with
the latest ALSA sources from the Hg repository.

BTW: i still have a spare au88x0 card... any devel want it?

I'd prefer it to be used to fix x86_64 issues with it.

mvg,
