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 received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/996906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
