On most (maybe all) videos, when played with VLC, pause and resume works fine as long it is only a second or two. When I pause the video for longer, after unpausing, the video plays fine but the audio cuts in and out a few times for several seconds. After these several seconds, playback is normal. It happens with videos which play properly in other video plays, and on every audio device I have tried.
The accepted answer to VLC no sound after Pause did not help.
I have had this issue for years I think. I'm currently running VLC 3.0.16 on Ubuntu 22.04.
