I do not have any specific knowledge about your audio card, but I
noticed one potential source of trouble: Your lsmod output shows a mix
of ALSA modules (snd_*) and OSS modules (*_audio). AFAIK this is not the
recommended approach; if you need an OSS compatibility layer then you
should use snd_pcm_oss, snd_mixer_oss and snd_seq_oss together with the
ALSA modules. You can try to blacklist the i810_audio module in
/etc/modprobe.d. Normally this should be configured for you
automatically if you run "dpkg-reconfigure linux-sound-base" and select
ALSA as the sound system. (I suspect this is set to "default" at the
moment.)
