I should explain exactly how I had my setup when I use to stream via: Shoutcast using Winamp. Maybe there is something I am doing that should be changed in my settings for Radio Boss?
I use an M-Audio PCI based soundcard. It has RCA L&R outputs and Inputs.
I use a Behringer 6 channel mixer.
I go from the Main out's on the mixer to the RCA inputs on the M-Audio card.
I go from the M-Audio outputs to the CD/Tape inputs on the mixer. There is a switch on the mixer that sends the Tape/CD to the Control room mix.
In Winamp there is a selection for the Input, you can choose "Winamp" or "Sound card"
When I wanted to stream my voice through the microphone, I would select "Sound Card". When I wanted to stream a song, I would select "Winamp"
I never had to use the "Push to talk" mic button, because basically when I was set to sound card, every sound on my computer went out on the stream.
I could monitor the music, hear my voice all without any latency or delay at all. I could take Skype calls, do whatever I wanted.
If Radio Boss has a way to set this up exactly the same way, I am all ears!
Thank you!
