[Laope]

got 2 pc setup via rtmp

few days ago installed the new update on both machines and today after 2hours of streaming my viewers told me i got audio desync. i have to restart the stream to fix it.
2 days ago got a similar problem, this time the stream, after 2hrs lost audio, the stream went mute. i have to restart obs to fix it.

this never happened before, the only change i made this week was update to obs 17.

here are the logs of both machines

looking the streaming pc log , this error repeats at the time the desync started

21:37:09.949: error: decode_band_types: Input buffer exhausted before END element found
21:37:09.949: error: decode_band_types: Input buffer exhausted before END element found

I have the same issue with audio desync after a while, I have a hunch it might be the 44.1khz audio being interpreted as 48khz one and drifting as result but I can't test right now sadly.

Tried lots and lots of different settings but it still continuously drifts, I'm reasonably sure the culprit is the media source on the 2nd PC.
