I have set the short name up in fact I created a new short name two nights ago and reset the whole thing up in Audiorealm. When I drop down the short name you can see in send out a search and it connects with Audiorealm fine. The play list up dates but no audio again. The VU meter work are moving and the stream works on nearly every system I try it on. But here is something strange. At work my Windows media player used to work fine, I up dated it and now it doesn't work with my stream at all. In audiorealm if I click on my website link the audio starts working right away after taking me to Loudcity.
I assume you've put in your Station's "short-name" under Config > Station Details.... ?
Encoders are encoding? VU meters are moving in SAM's Encoder window? Have you tried opening your stream in another 3rd party player like WinAmp or other?
