Re: Audio Issue when upgraded to 9.2.0 on content with DRM (Smooth).
We are dealing with Smooth streams as well. We have Playready drm. I checked on Roku Ultra 4640X 9.2 4131-29. No isse with audio. Also we did not get any feedback from our customers about broken sound.
I believe you have few options to debug:
1. errorStr, errorInfo produce any debug data
2. downloadedSegment you should check if you see SegType = 1 which is audio file. If you don't see it that means roku is not even downloading audio chunks, if you see it there might some decoding/sync issue.
3. availableAudioTracks, audioFormat are populated correctly?
