I am having problems getting the m-audio usb quattro to work on my system (Debian Sid, kernel 2.4.22, ALSA 1.0.2c).
This is the current state: - module loads ok - pcm interfaces show up ok
However, issuing "aplay -D hw:1,0 test.wav" gives
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
underrun!!! (at least 0.028 ms long)
underrun!!! (at least 0.008 ms long)
underrun!!! (at least 0.011 ms long)

underrun!!! (at least 0.008 ms long)

and I don't hear anything. Any help appreciated.
