--- Comment #27 from Raymond <[email protected]> --- (In reply to rkfg from comment #26) > So I've bought a laptop with VIA sound as well and it also have > skips/stutters. I worked around it on both systems with these steps: > > 1) in /etc/pulse/default.pa added tsched=0: > load-module module-udev-detect tsched=0 > > 2) to reduce latency set in /etc/pulse/daemon.conf: > default-fragments = 4 > default-fragment-size-msec = 1 > > The final latency is a product of these numbers, 1*4 == 4 ms which is > acceptable. The number of fragments should be at least 2 so the least > latency possible is 2*1 == 2 ms. I don't know if there's a real difference > between 4 fragments of 1 ms each or 2 fragments of 2 ms each. Try some > experimenting. At least now I don't have latency increase and sound doesn't > skip on pavucontrol launch, though it still skips on LMMS launch. > are there any difference when using four periods or two periods ? 1ms at 44100 Hz has 44.1 frames aplay select buffer size nearest to the selected time aplay -D hw:0,0 -v --buffer-time=4000 /tmp/fr025.wav aplay -D hw:0,0 -v --period-time=2000 --buffer-time=4000 /tmp/fr025.wav -- You are receiving this mail because: You are the QA Contact for the bug.
