            Bug ID: 92071
           Summary: USB audio latency is (unnecessarily) high
           Product: PulseAudio
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: alsa
          Assignee: pulseaudio-bugs at lists.freedesktop.org
          Reporter: arun at accosted.net

Since we started respecting the BATCH flag, USB audio device latency has been
fixed at 100ms in our default config.

The BATCH flag is probably not what we want here, so we need to have finer
grained reporting from ALSA, which we can use to configure rewind safeguards
for tsched mode (instead of always disabling it).

Faililng this, I'd like to at least have workaround for USB until this is fixed
preoprly.
