checked it, it's the correct source (back line in) same as it has always been (I haven't touched it since install)
the cable is still connected and I can hear the scanner thru my PC speakers, the record volume is set all teh way up, I dont understand why it's not working, maybe a bug with the Stream Transcoder ?
Also in Options or Settings (in Stream Transcoder) check that the correct audio device (sound card) is being used. I know it can be switched so you can use a secondary sound card to stream audio, so check to make sure that is on the right sound card.
I don't have a copy of STWin on this computer, but I'll look into it further later tonight when I'm sitting in front of my other computer.
