Underruns in the log
Same with VIA VT1708S. When I start pavucontrol it skips hardly and almost
stops sometimes. Because of that latency increases and may get up to 80 ms
which is unacceptable as PulseAudio's goal is to provide low latency audio. Of
course, it doesn't happen with pure ALSA. I already set all priorities to the
maximum, doesn't seem to help. My kernel is preemptive (not the default
Debian's one, it's even worse with it):
Linux work 3.18.0-pf0+ #1 SMP PREEMPT Tue Jan 13 09:21:17 MSK 2015 x86_64
GNU/Linux
I have this enabled in daemon.conf:
high-priority = yes
nice-level = -19
realtime-scheduling = yes
realtime-priority = 15
exit-idle-time = -1
log-level = debug
This doesn't happen with tsched=0, but the resulting latency is horrible in
that case. Pure ALSA has negligible latency and doesn't skip at all.</pre>
