The alarm clock feature only works with playlists. One common use of audio in alarms is the, gasp, clock radio. I know it’s easy to make an MPD playlist with a stream url. Please add this feature to Volumio so it would be possible to use it as a clock radio.
Solved. Found out how to create a playlist from a queue. The feature I wanted already exists.
It would be useful for people searching in the future if you could summarise what you did…if you had problems, others probably will too.
I discovered elsewhere in the Volumio forums that you can play a radio station and from the queue panel put the contents of the queue into a playlist. I’ve looked for something like this before and only found it today. Don’t know if it’s a new feature or I just wasn’t looking in the right places.
