Changeset 15893 breaks passthru for me (emu10k1). The reduction in
buffer_time throws underruns and I get no sound. Setting this back to
500000 fixes it.

My fragment_size also gets calculated to 6400 which is not cleanly
divisible for 6 channels @ 16-bits. It still works like this, but I'm
not sure what impact it actually has.
