And so earlier today I went out and bought an AudioPCI card.
You were right, Jaroslav. The AudioPCI card's midi port works
just fine. Frank's Sequencer core and test utilities run beautifully
with it.

I really hate to say this, but now I'm having trouble with
full-duplex audio and the AudioPCI card. I don't yet want to
report a bug, until I've had more time to verify that I'm not
doing something wrong in the code I'm writing (Csound w/ ALSA
driver support), but may I ask: Are there any known bugs in the
AudioPCI driver (especially in the case of full-duplex operation)?

The card appears to be configured properly as I'm able to record
and play audio files with arecord/aplay without any trouble.


Thanks for the help,

Fred
