I agree. I'd like to figure out exactly which ALSA routine is not giving back
proper feedback, so that I can send a bugreport to the ALSA people.

To this end, I experimented a bit with ao_alsa9.c file. In parcticular,
I tried to figure out whether there is difference in return values of the
get_delay function in ao_alsa9.c for my two soundcards. This was not the case,
both returned values in the range of .3. The return-value is assigned in line
1116 of ao_alsa9.c. Other suggestions are called for!

The M-Audio revolution is a very new card and it's alsa-driver seems to be
still under development. I imagine the ALSA people would appreciate proper
