I’m another with audio sync problems. For me it has only started happening in the last week on my Roku Streaming Stick+.
Frankly live tv on my Roku is unwatchable. I already suffered from the picture getting stuck and juddering (Roku update to 9.3.0 causes live tv video to freeze) and now add these audio issues to the pile.
Direct stream on the video and a transcode on the audio and after a min or 2 my audio will be completely out by a matter seconds, it’s not even marginal. Even if i force transcode of the video it will still drift out of sync… Very frustrating. I don’t have any workaround!
