I am using a Yamaha MG10/2 sound board and a USB Behringer U-control UCA202 for my soundcard...when I stream music through RadioBoss everything sounds fine but when I try to broadcast live and use mic then there's an echo (on mine and the caller's end), there is static when it's silent, audio cuts in and out and sometimes I get feedback in my headset...I have to close RadioBoss reopen it or turn the mic on and off to relieve this problem... what is causing this problem and how can I get a clearer broadcast?
