    Some time after changing my HTPC from RPi3 (which is now an octoprint server) to RPi4 I discovered that some of my older video files have a very choppy (jerky?) sound. All the problematic files are TV-rips and they play fine on PC with VLC. The VLC shows the H264 - MPEG-4 AVC (part 10) as video codec and MPEG Audio layer 1/2 (mpga) as audio codec. The display is an old Panasonic plasma TV connected via HDMI.

    The problem is not audible for first ca. 30 - 90 seconds, then it starts to increase, pause/playing the video helps for the same time again. Video playback is smooth all the time.

    System information shows CPU utilization up to 40%, the temperatures are quite low. I have tried to enable or disable audio passthrough without any observable change.

    I'd be grateful for any ideas.
