            Bug ID: 205979
           Summary: Raspberry Pi2 loses audio after some time
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: arm
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: arm
          Assignee: freebsd-arm@FreeBSD.org
          Reporter: karl@denninger.net

After some (relatively short) period of time on 11-Current with the Raspber=
ry
Pi2 audio fails in a "mute" state.  Some programs attempting to access audio
(e.g. mpg321) will print a diagnostic on the console, others (e.g. espeak)
simply hang.

If there is a diagnostic it is of the form:

pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel d=
ead

There appears to be no way to clear this condition once it occurs other tha=
n a
reboot.
