If an audio only radio service is transcoded and the appropriate SMIL file is created an HLS m3u8 manifest can be got from the server, however it is not possible to get the DASH mpd one. If a video stream is added then it is possible to get the DASH mpd file from the server. DASH is enabled in the configuration.

Is this a bug or a feature that audio only can't be streamed or is there some specific config for this? Has anybody else streamed audio only radio services using DASH?
