No audio on HLS streams

[n76]

HLS streams have good video but no audio. Looking at the video definitions supported by Roku and looking at the video definitions served up by my PeerTube instance it seems they should work.

Current work around is to play MP4 streams instead of HLS.

May be an issue with the HLS streams being generated by PeerTube. My test stream from my instance fails HLS validation:

Hi. Thanks so much for your past work on this. I'm new to this. Which of those warnings and errors is what stops Roku playing the audio (all of them?) and are PeerTube developers aware of the problem?
