Hiya, I've been playing with modern releases of pulseaudio. In release 0.9.12 on an arm embedded system, the cpu load went from around 12-16% to under 4%. AWESOME! But something seems broken with module-null-sink. I looked at git and Lennert had a comment about teaching module-null- sink about rewinds. Debugging is always easier on x86 so I tried a simple null sink there. Logs of output are below. Where should I start looking to address this? Any clues or breadcrumbs gratefully received :) Thanks Nick I checked out the "master" branch from git, built it and got the following message: > nick at nick-desktop:~$ paplay --device=test_null_sink ~/Sony\ CD-ROM\ > Test\ Disk\ Type\ 3.0/Cantibile-Op-17.wav > Connection failure: Connection terminated > Stream errror: Connection terminated Looking at the output of pulseaudio's log I see the following... > D: module-suspend-on-idle.c: Sink test_null_sink becomes busy. > D: memblockq.c: memblockq requested: maxlength=33554432, tlength=0, > base=4, prebuf=0, minreq=1 maxrewind=0 > D: memblockq.c: memblockq sanitized: maxlength=33554432, > tlength=33554432, base=4, prebuf=0, minreq=4 maxrewind=0 > I: sink-input.c: Created input 0 "/home/nick/Sony CD-ROM Test Disk > Type 3.0/Cantibile-Op-17.wav" on test_null_sink with sample spec > s16le 2ch 44100Hz and channel map front-left,front-right > > I: protocol-native.c: Requested tlength=250.00 ms, minreq=20.00 ms > D: protocol-native.c: Traditional mode enabled, modifying sink usec > only for compat with minreq. > D: memblockq.c: memblockq requested: maxlength=4194304, > tlength=44100, base=4, prebuf=44100, minreq=3528 maxrewind=0 > D: memblockq.c: memblockq sanitized: maxlength=4194304, > tlength=44100, base=4, prebuf=44100, minreq=3528 maxrewind=0 > I: protocol-native.c: Final latency 460.00 ms = 210.00 ms + 2*20.00 > ms + 210.00 ms > D: protocol-native.c: Requesting rewind due to end of underrun. > D: module-null-sink.c: Requested to rewind 352800 bytes. > D: sink.c: Processing rewind... > D: sink-input.c: Have to rewind 352800 bytes on render memblockq. > D: module-null-sink.c: Rewound 352800 bytes. > D: protocol-native.c: Requesting rewind due to end of underrun. > D: module-null-sink.c: Requested to rewind 352800 bytes. > D: sink.c: Processing rewind... > D: sink-input.c: Have to rewind 40012 bytes on render memblockq. > D: module-null-sink.c: Rewound 40012 bytes. > D: protocol-native.c: Requesting rewind due to end of underrun. > D: module-null-sink.c: Requested to rewind 352800 bytes. > E: sink.c: Assertion '!s->thread_info.rewind_requested' failed at > pulsecore/sink.c:632, function pa_sink_render().
