I believe I am also having the same issue. On Youtube, Spotify, Youtube music, or any other audio source from the browser. The audio will cut/crackle for around 1 second, then the audio we be behind by varying amounts. This does not occur with any audio sources from other application, and is not my headphones either, as the audio works fine on my phone. (i have also done lots of tests/attempted fixes by checking the Bluetooth connection and I believe that this issue is related to the browser.)
