Audio track slower than video (self-hosting)

[julianwitzel]

Description

When rewatching a recorded video I realized that the audio is much slower than the video. Also it is not affected by any speed settings in the player. So what I say does not match anymore what you see. This prevents me from actually using it in my company at this point in time.

I was thinking it might have to do with the media server setup. I opened an separate issue for that: #1507

Could someone assist to debug?

Reproduction

1. Upload a video using the desktop app
2. Click the link to watch it
3. After some time your realize the video is faster than the audio

The audio and video sync architecture had a round of fixes in July, and 0.4.3, the version this was reported on, is well out of date now. This specific drift is believed resolved, please re-test on the latest version and open a fresh issue with logs if audio still lags behind video.
