Summary:                    Speaker test hangs
Description: 
After applying the patch to the library that took out the check for a
proper "start_threshold" (file .../alsa-lib/src/pcm/pcm.c around lines 834
or so), I attempted to try a speaker test again.  It hung right after
outputting "0 - Front Left".  I did an strace and the results are included
in the file attached.  I attempted to vary the sample rate (to 44.1 kHz)
with little luck.  The wierd thing is that I can execute 'aplay' (with the
default device) and get a '.wav' file to play nicely.  I can even get a
multi-channel (4 to be exact) ".wav" file to go thru 'aplay'.  Why
speaker-test doesn't work is beyond me.  The problem is that I appear to
use similar techniques in my own programming as speaker-test, and my
program doesen't do that well.  Being as how speaker-test IS part of ALSA,
I thought I would submit the bug report against it.

If other tests need be preformed, I'd be VERY happy to do them.
