It's possible that OSS emulation was broken on some exotic cards.
One necessary thing is to find out which condition breaks the thing.

For example, try to disable OSS rate and format conversions via proc
file as described in OSS-Emulation.txt.  It's one of the evil roots.
If the app still works but the problem persists, then check the
running condition in card0/pcm*/substream*/* files.

Also, trying aoss wrapper would be a good idea, too, in general.
