On the bright side, Cheap Intel products mean a large install-base so a
better chance of finding solutions. So far on Linux my crap ac97 card works
a lot better (at all) then my good EMU 1616m (fortunately bound to change
with the next ALSA update)

dude, you're scaring me.....

Right, so it does input or output but not both at the same time. Years ago
that would be "crap" but now I'm leaning towards "something must be wrong"
as "duplex" is hardly a new and exciting thing anymore.

I pulled a quick Google to see if this is really a card that has no duplex
(recording while playing back) and stumbled upon something that might be
even better info;


Did you see that? Did you perhaps disable the modem?

That would make it a easy fix, otherwise we'll have to trace if the card is
indeed crap or if ALSA is wrong or -oh unthinkable of options- ChucK might
have a issue.

I also saw lots of other pages about issues with this chipset but they
seemed to be about it not working at all instead of having to pick which
half works so that's probably a different sort of thing.

Weird stuff, I hope it's the modem.
