This error is always there. It seems everything isn't implemented in the
alsa api, but it works anyway.

I don't know what the setup is like on your soundcard with alsa but
on mine, I have 2 devices.
hw:0,0 which is the normal "analog" device and
hw:0,4 which is the spdif/iec958 device.
But the thing is that I have to use the hw:0,0 device always, both
for normal and spdif output.

Using /dev/dsp when you are running alsa will only get you the
alsa oss compatibility device, which doesn't work as good as true oss normally.

Have you tried editing out the ac3 channel_config in the oglerc file
so you don't get spdif output, but normal analog instead?
Does that give any sound?

Did you try the above after you had shutdown esd?

This is probably because the alsa oss compatibility device doesn't support
spdif or some other function we are trying to use. 


Anyone else on this list that has any suggestions to which alsa device
to use on an i810 chipset?
