Hmm, what about "ecasound -i:file.wav -o:alsaplugin,0,0"? I tried
1.7.7r11 with my AWE64Gold(isa) without problems (ALSA 0.5.5).
I might have asked about this already, but anyway, how ecasound was
installed... RPM, recompiled? If recompiled, did you have the
correct ALSA header files installed (/usr/include/linux/asound.h and

I got a few underruns (1 or 2 most of the time), but no sync problems.

This is probably wrong... input card0, device1 (is this a typo?),
subdevice0. As subdevice is a low-level concept, you shouldn't need
to specify it in normal use (default is -1, not 0).

This is an invalid command line.
