I would say that the behavior changes. When I try to play a 6-channel video the sound becomes choppy (not a CPU issue as the CPU is used for about 80%) and pulseaudio prints the following error messages:
E: module-alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! Most likely this is an ALSA driver bug. Please report this issue to the ALSA developers. We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail_update() returned 0. When I remove the "tsched=0" thing the messages disappear and the sound is back to normal. However, this problem does not manifest when simply playing a simple stereo mp3 file. I am unable to reproduce the original bug, either with or without the "tsched=0" setting. -- pulseaudio sometimes pauses playback for 5 seconds https://bugs.launchpad.net/bugs/319118 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
