Thanks for the patch. It's a little better, but the sound quality isn't
thrilling either. And now, if I try to play back /tmp/test.au with aplay
it still reports "Unsigned 8-bit, Speed 8000 Hz, Mono" and it sounds
awful. (arecord and then aplay still work great)

Has anybody got speak freely to work with alsa in full duplex? What are
the right options to compile? (-DAUDIO_BLOCKING?)

cu,
Lars
