[mythtv-users] OSS (i810_audio) Driver Duplex Issue (asus pundit)

[Steele Price]

The more I see comments about this chipset the more I really think it's a
POS...
Too bad it's embedded on so many motherboards or no one can figure out how
to fix the drivers.

My alsa drivers are working fine in full duplex under 2.4.21(vanilla) with
ck3 patches, don't know if this would be true under a plain vanilla kernel
but maybe, there aren't that many changes to sound in the ck3 patches.  I
also HACKED my alsa driver to add support for SIS 7012, all I did was copy
the SIS Generic line and changed the name, seems to work fine for everything
except PCM over optical out.  Now if I could just figure out how to make PCM
over optical out work I'd have a completely working driver for this chipset.

And, yes, I've tried using ALSA.  With rh9, alsa worked like ass, and
the oss drivers worked fine.  I'm trying to migrate to 2.6.0, but the
oss comes up 1/2 duplex, and the alsa has all sorts of problems
(skipping, etc..)  I am riddled with kernel errors indicating intterupt
problems...

	kernel: ALSA sound/core/pcm_lib.c:214: Unexpected hw_pointer value
	(stream = 0, delta: -936, max jitter = 8192): wrong interrupt
	acknowledge?


Thanks in advance,
