I have alsa 0.6pre-- and am having some difficulty compiling ac3play. Are patches available? I've tried to make modifications, but when run, alsa asserts that my pcm_setup is invalid. Does ac3play work with the 0.5.9 series? BTW, I'm using a Hoontech 4dwaveNX. I have tried to use ac3spdif, but with no success. Jeremy Erwin <jerwin@osf1.gmu.edu>
