Hi Roku Support Team,
I think there is a problem with Roku not passing through DolbyDigital 5.1 HLS streams properly (at least in SceneGraph), the audio is muxed to stereo. I tested this on Roku 4 player
How to reproduce:
- Use this test packaged stream that contains Dolby 5.1 audio track : http://220.127.116.11/assets/asset5.1te ... 1test.m3u8
- Play it in SceneGraph Video node while connected to 5.1 capable receiver via HDMI and note audio output is "stereo"
I have tried all the options in Roku audio menu and used alternative HDMI sources to make sure the problem is not on receiver side. I am pretty confident the issue is with Roku OS. So far the only application capable outputting Dolby Digital (+ however) is Netflix, but it is not written in SceneGraph, it is a native app.
Please advice and thank you!
