Yes, 64 / 3 = 21 .
That stinks (but if it's necessary for decent

What's the max number of MIDI ports that's supported by ALSA?
There can be up to 8 rawmidi devices per card, but each device can
have an unlimited number of subdevices.
OSS emulation

The answers to the questions above - are they in the docs?
Use the Source, Luke! :-)
Note that applications shouldn't rely on these

Actually, I disagree. It's an ALSA bug. The warning is created if
the AACI close method is called while the DMA or IO is still running.
If DMA is still running here, we've already freed the DMA buffer, so
we're either reading from or writing to memory

Yes. Thanks for your replay. Maybe I should send the
mail to arm-linux mailist.
PS. Could you recommend some docs about the ALSA
internals and Low level drivers? There are too many
docs

I've been trying to write an ALSA driver for the AC97 port on an
embedded AMD au1000 MIPS processor but am having some difficulties. The
processor's DMA controller has two buffers which automatically toggle
back and forth once the buffer is full. My problem is that when I
playback a wave file
