Xmms with the OSS output plugin doesn't really work.  It plays like 10
times too fast and the output is not really recognizable.

This is the debug output of osspd:

I guess this has something to do with the too small frag size, but
couldn't figure out how all this works in prepare_streams() and
padsp_write().

Thanks,
