STR: 1: Open https://www.youtube.com/watch?v=XqLTe8h0-jo 2: Seek to 60s 3: Change video resolution to 1080p 4: Wait for playback to restart 5: Seek to 5s What's happening: after seeking to 5s the spinner goes on while data is being rebuffered and playback restart. However, there's now no audio. After about a minute audio will start playing, but about 1 minute A/V sync off from the video. What should be happening: Audio and video starts playing, in perfect sync.

Decode ahead will be stopped when seeking or when switching resolution.
