if you compile in OSS mode (no ALSA),
to run in an ALSA setup, use alsa-oss and do something like:
LD_PRELOAD=../alsa/lib/libaoss.so ./oa
You may need to edit card.c and change:
  int numfrags=1;
with:
  int numfrags=3;
or a bigger value (4 or 5).
If you don't do that, you may get many "tic" all the time.
