Subject: i810 audio, problems with both GPL and 4Front driver


FYI,

On my machine, the changes in
http://marc.theaimsgroup.com/?l=linux-kernel&m=100651447318071&w=2 or
2.4.17-pre1 don't fix the KDE problems, as alleged. artsd still exits
after consuming too much CPU. I've tried reducing fragment size to 512
with no effect.

If it makes any difference to the driver, the kernel is running with
APIC's and ACPI enabled on a uniprocessor build (Wow, acronym soup. ;)

for what it's worth, 4Front's binary driver (3.9.5, 3.9.6) has problems
too on this machine. KDE works but there are audio pops/speedups/stops.
(xmms, in particular, likes to stop for a while, then resume, sometimes
after a speedup.)

Just because I've been hearing about this stuff forever and the powers
that be didn't take my i810_audio.c driver version 0.05 for some reason,
I've place my 0.05 i810_audio.c file on my web site for anyone
interested in testing it to see how it does.
