Hm, that was a bit early. Now it has "happened" ONCE with the 5.1.0-050100rc2-generic kernel. I think the battery of the laptop was pretty low at the time. Youtube audio went totally out of sync with video.
Restarted to 4.15.0-43 to see what that does with youtube. It had pauses in getting the video (the circle going round) but when picture came back it was still in sync with audio. Restarted back to 5.1.0-050100rc2-generic again. Now everything was ok there. Also computer shows i have powersave governor on. Another notebook with (Celeron N3350 and) powersave has no problems at all though. I should probably also try a clean install. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1820409 Title: Audio stutter after update Status in linux package in Ubuntu: Confirmed Bug description: After some update: Audio stutters in VLC Video and audio stutters in Youtube I think cpu usage might be bigger in VLC too, over 20% vs. below 20% earlier (one thread gets full 100%?) Stuttering kernel at the moment is 4.15.0-46-generic. Kernel version 4.15.0-43-generic definitely worked good. Cant remember if i could get slight stutter from previous version version -45. Tried also lowlatency and 4.18 kernel, bad stuttering in those.
