I hear ringing then three tones repeating

Playing a station that I set up and has worked in the past I now hear ringing first and then a series of tones - low med then high - and the tones just repeat. What causes this?

I have the same problem now and then. Was freaking out for a bit because I thought I was using my minutes.

Its just a simple audio file that is set to play when you connect to the stream while Moodio buffers the radio stream it will be transcoding for you (some players disconnect if they don't receive audio data immediately). There are countless threads on this topic already, by the way. Search is your friend. :)

Hmm. I would think something as a common as the question would then appear in the FAQ since it is so Frequent....
