OSS Audio doesn't work properly for Quake3 in 2.6.10 but it worked in 2.6.6.
In fact I have the same problems in 2.6.9-rc1 so I assume 2.6.9 is affected as
well. This is with the Intel i810 drivers.
Quake3 just prints "dropping sound" over and over again and doesn't output any
sound in the actual game (the menus seem to work 50% of the time). I assume
this is related to Quake3's use of the memory mapped audio interface. Perhaps
it's never getting interrupts through the ioctl interface?
Here is the lspci info:

I tried it with pci=routeirq but no change.
The strace from quake running on the two kernels looks essentially identical.
Here are all the syscalls that look relevant from the 2.6.10. The output is
essentially identical for 2.6.6 except for the memory addresses, pid, and the
number of omitted read calls where the ellipses are. Note, that it *does*
print "sound system is muted" in 2.6.6 as well, but it works fine.
