I’m glad I’ve found this thread, I too am having Audio sync problems with a Roku Streaming Stick+, which I am pretty certain only started happening in the last couple of weeks. I certainly did some server upgrades but annoyingly it also coincided with the Roku updating to 9.4.
My Live TV audio is transcoding to MP3. Now i’m not exactly sure what it was doing before but at least this looks promising to explain my problems. I will try downgrading to see if I notice any difference.
For reference I had also come across this thread (Audio out of sync) about audio sync problems on Roku, but i didn’t have any issue until the last couple of weeks whereas that thread is a couple of years old but still open.
