Just starting to learn about Coherent myself (Coherent GT, specifically). I think I figured it out, which is the fact that the audio tag can only receive webm type files, and none of the streams are webm, so it’s back to the drawing board for me as my implementation relies on browser based audio.
Maybe some of your inputs are also not implemented in Coherent GT?
Thank you for the lead on the devkit. Will come in handy!
