#500: module_jack_sink + module-suspend-on-idle = xruns
--------------------------------+-------------------------------------------

Component: module-jack-* | Severity: normal
Keywords: |
--------------------------------+-------------------------------------------
If I use pulseaudio over Jack with module-suspend-on-idle timeout=0, then
JACK reports an xrun (tens of milliseconds) for each started or stopped
stream. I.e., mplayer -ao pulse = xrun at start and xrun at the end of the
song, mplayer -ao jack = no xruns.
Software versions: pulseaudio 0.9.14, jackd 0.116.2.
