Yes I did, and no there isn't.

Well, the blocking thing is peculiar.
"buffer -S1024 </dev/zero >/dev/audio" writes 120kB into /dev/audio,
then it blocks. (buffer was the first thing that came to mind that can
output how much data it has copied.) When I call it again, it blocks
immediately. Now, if I start mpg123 and subsequently call buffer again,
I can again write 120kB to /dev/audio before it blocks. So mpg123 seems
to perform some kind of partial reset.
