I was now able to reproduce this. For me this doesn't seem to happen 100% of the time (I test by running "vlc ~/misc/sync_test.mp4", observing the A/V sync, closing vlc, waiting for the sink to suspend, and trying again). The small hardware buffer size that I have (371 ms) might make noticing the delay harder, if the delay is variable, but if it's always one full hw buffer size in length, then I should be able to reliably notice it... I'll build a custom kernel next with a bigger audio buffer, and see if that changes anything.
Btw, Remi, you said that "this affects all VLC versions [...] with PulseAudio 2.x." Do you mean that this doesn't affect 3.0? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069232 Title: Sound lags when opening video files To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/1069232/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
