Thanks for the reply Clemens,
i had made the changes above to samples (I dont know what i was
thinking. :-) ),  anyways the issue i was having with the -22 had
something to do with setting some software parameters.  by commenting
out all software parameter stuff. it worked well.

Do you have any idea on how i can target certain channels. for example
have a sound play out only the left or right channel?  i cannot find any
documentation on the int he alsa docs.

and if any alsa list admin is reading,
i still have not recieved my digest of the list for over a week, is
their an issue with the alsa daily digest?
