--- Comment #17 from Adam Goode <adam at spicenitz.org> ---
I have built pulseaudio from git and also want to figure out how to use tsched
with my USB devices. The 99.95ms fixed latency is horrible.

The same quick hack (of not disabling tsched in BATCH mode) appears to work for
me. Now I get "configured latency: 16.00 ms; range is 16.00 .. 743.04 ms".

Note that if I use module-jack-sink I get a fixed latency of 2.67ms (as
configured by jack), so the hardware can do much better than 16ms, just not
directly from module-alsa-sink.

What can we do to fix this?
