Here is an output of a movie that gives no sound on the digital out, but does 
make very jittery sound on the analog out:

And here is the output of a movie that makes non-continuous sound on the 
digital out (the digital signal disappears for about half a second then comes 
back for about half a second...). Sound on the analog out is almost error 
free.

I have beta7 and as I said, it works with all other applications. But I'll 
try beta10 soon.

Oh, I thought OSS and OSS/Pro refer to the consumer and professional DAC in 
the card (there must be something like that, although I don't understand 
why). Ok, it means OSS/Free vs OSS/4FrontTechnologies, right? But when I have 
alsa, it just emulates OSS, so I have neither of them...
