I'm not completely sure, but I think the answer is no. In fact doing a
reliable output to the port is already quite challenging ;-) I think
this can only be done through a printer driver or something similar.

Yes, there are plans. In fact I was planning to already have it
implemented by now. And it wouldn't be hard to do if we had a decent
sound system standard. The SSS is crap. It's good enough for the Q40
"sound system" (which is no system at all but just two D/A converter
which get fed with new data in a 20kHz interrupt routine), but for
anything that uses DMA looped buffer (i.e. all "real" sound systems)
it's very hard to implement in a proper way. I gather the GoldFire
will have a decent sound chip, too, so in the end it will face the
same problem. I'm not really sure how to solve this issue, maybe it
would be the best to design a new sound standard. This could be done
in a way that it suites both DMA based systems and the Q40
interrupt/converters combo.

And please no comments about me "attacking the Qx0". What I wrote
above are simple facts.

Cheers, Marcel
