Severity: normal

For some files switching audio tracks causes de-synchronisation of audio.

The more times I switched audio track the more delay between audio and video.

In console output after switching audio track several times I got

  error decoding the audio block

and "A-V:" field value increased with each switching:

  A:4254.9 V: 155.4 A-V:4099.461 ct:  0.443 3728/3728  2%  4%  2.7% 17 0 

After seeking through the media (LEFT/RIGHT keyboard command) playback become
synced (and "A-V" parameter changes to almost zero).

Example of output:
