I am not able to play any music from the web interface on Firefox or Google Chrome. I get the error “The track cannot be loaded. The next track will play automatically in a few seconds… You may have a connectivity issue.”
The same track can be played successfully by a user on a Subsonic client (in this case, Clementine).
Firefox inspect gives errors like:
Media resource ... could not be decoded
Media resource ... coudl not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR
I have media transcoding enabled and sufficient horsepower behind the container to transcode audio.
