Summary

An (As of yet) not pinpointed issue caused Jukebox to fail to output to TX and Online for over an hour, despite the jukebox service still playing out music on Icecast and through the studio faders.

Rough Sequence of Events

At around 11:02 Jukebox stops playing out audio to streaming and TX. Nobody notices as nobody listens to us, and the dead air detector sends no emails (Not that it could do much other than "We detected a silence, jukebox has been switched to jukebox!")

Having finished his morning lectures at around 12:00, MM enters the station and has a quick check of Jukebox via a desks AM feed. MM notices that no sound is coming out. Checking the feed from the AM2, Yamaha, and Icecast show the same. In a nervous panic MM alerts the committee, switching to red and playing out the Jukebox feed via the Pres Pc (Through Icecast, as Jukebox still was playing audio itself) at 12:11. At the time MM didnt know online was off as well as AM so ran into TX and stared at it. The transmitter was sitting there all happy and smug, no reflected power to speak of, just the ominous "Audio break" LED latched on. Having no idea what to check, MM comes back to the studio after a good 10 minute stare and contemplate to find that Jukebox is back on air playing as normal.

Turns out during this thoughtful TX stare someone came in and thought "Why the fuck is Red on thats not right!" and switched to Jukebox, which suddenly worked as normal. MM is very confused at this and declares the incident over.
