--- Comment #72 from Alessandro Ferri <[email protected]> --- I think this is a substantial difference in the behavior of pulseaudio compared to the two Kernel. With kernel 3:12:29 increasing steadily up to 745.99 ms: (55 620 | 0000) I: [alsa-sink] alsa-sink.c: Increasing wakeup watermark to 745.99 ms With kernel is 3:12:25 fix one time to 30 ms: (11.863 | 0.000) I: [alsa-sink] alsa-sink.c: Increasing wakeup watermark to 30.00 ms The same thing with minimal latency: With kernel 3:12:25 no increasing latency, with kernel 3.12.29 Increasing latency up to: (48 424 | 0256) I: [alsa-sink] alsa-sink.c: Increasing minimal latency to 756.00 ms (In reply to Raymond from comment #71) > > latency seem fixed at 105ms 3.12.25 with 30ms wakeup > > > > 126| 0.000) I: [pulseaudio] sink-input.c: media.name = "Shairport > Stream" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: application.name = > "AirAni-b35336" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: native-protocol.peer = > "UNIX socket client" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: > native-protocol.version = "26" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: application.process.id > = "4160" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: > application.process.user = "pi" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: > application.process.host = "raspberrypi" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: > application.process.binary = "shairport" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: application.language = > "C" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: window.x11.display = > ":0.0" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: > application.process.machine_id = "d3670ff77a0bb988a953e7f053a3f4e7" > ( 9.126| 0.000) I: [pulseaudio] sink-input.c: > module-stream-restore.id = "sink-input-by-application-name:AirAni-b35336" > ( 9.139| 0.012) I: [pulseaudio] protocol-native.c: Requested > tlength=250.00 ms, minreq=20.00 ms > ( 9.139| 0.000) D: [pulseaudio] protocol-native.c: Adjust latency mode > enabled, configuring sink latency to half of overall latency. > ( 9.140| 0.000) D: [alsa-sink] alsa-sink.c: Cutting sleep time for the > initial iterations by half. > ( 9.140| 0.000) D: [alsa-sink] alsa-sink.c: Cutting sleep time for the > initial iterations by half. > ( 9.149| 0.008) D: [pulseaudio] protocol-native.c: Requested > latency=105.00 ms, Received latency=105.00 ms > ( 9.149| 0.000) D: [pulseaudio] memblockq.c: memblockq requested: > maxlength=4194304, tlength=25580, base=4, prebuf=22056, minreq=3528 > maxrewind=0 > ( 9.149| 0.000) D: [pulseaudio] memblockq.c: memblockq sanitized: > maxlength=4194304, tlength=25580, base=4, prebuf=22056, minreq=3528 > maxrewind=0 > ( 9.150| 0.000) I: [pulseaudio] protocol-native.c: Final latency 250.01 > ms = 105.01 ms + 2*20.00 ms + 105.00 ms > ( 9.150| 0.000) D: [alsa-sink] alsa-sink.c: Cutting sleep time for the > initial iterations by half. > ( 9.151| 0.000) D: [alsa-sink] alsa-sink.c: Latency set to 105.00ms > ( 9.151| 0.000) D: [alsa-sink] alsa-sink.c: hwbuf_unused=334280 > ( 9.151| 0.000) D: [alsa-sink] alsa-sink.c: setting avail_min=87319 > ( 9.152| 0.000) D: [alsa-sink] alsa-sink.c: Requesting rewind due to > latency change. > ( 9.152| 0.000) D: [alsa-sink] alsa-sink.c: Requested to rewind 352800 > bytes. > ( 9.152| 0.000) D: [alsa-sink] alsa-sink.c: Limited to 347040 bytes. > ( 9.153| 0.000) D: [alsa-sink] alsa-sink.c: before: 86760 > ( 9.153| 0.000) D: [alsa-sink] alsa-sink.c: after: 86760 > ( 9.153| 0.000) D: [alsa-sink] alsa-sink.c: Rewound 347040 bytes. > ( 9.153| 0.000) D: [alsa-sink] sink.c: Processing rewind... > ( 9.154| 0.000) D: [alsa-sink] sink-input.c: Have to rewind 347040 bytes > on render memblockq. > ( 9.154| 0.000) D: [alsa-sink] source.c: Processing rewind... > ( 9.155| 0.001) D: [pulseaudio] core-subscribe.c: Dropped redundant > event due to change event. > ( 9.156| 0.000) D: [pulseaudio] reserve-wrap.c: Device lock status of > reserve-monitor-wrapper@Audio0 changed: not busy > ( 9.159| 0.002) D: [pulseaudio] protocol-dbus.c: Interface > org.PulseAudio.Core1.Stream added for object > /org/pulseaudio/core1/playback_stream0 > ( 11.862| 2.703) I: [alsa-sink] alsa-sink.c: Underrun! > ( 11.863| 0.000) I: [alsa-sink] alsa-sink.c: Increasing wakeup watermark > to 30.00 ms -- You are receiving this mail because: You are the QA Contact for the bug.
