OP5: Sound from videos (IG/FB/YT) are delayed

Hey guys,

Since few days I have the problem that the sound from videos over Instagram, Facebook or Youtube are delayed.

The video stuck after few seconds playing, and starts again, while sound is delayed few seconds..

Just a restart of the device solve this problem, but just for few minutes.

OP5 Stock firmware - nothing changed - latest update Every app is up-to-date

Playing own videos in gallery works perfect.

Edit: also videos received and played via whatsapp
