buy a small outboard audio mixer..many available..Beringer makes one for about 40.00..get a decent mic..patch from the line out on the mixer into the mic in or line in on your pc's sound card..there ya go..now you can talk over your music when played over the net..doesn't matter what software is being used..or browser..you will need a host to channel the show out to the web..sites like Ustream, Livestream, or Justin tv..there are many others..those are the most used..it's free to use as well...up to a point..Livestream, where I do a show gives you space for up to 50 listeners at any given time at no charge....that's more than some AM radio stations have...lol Cost of a mixer and a decent mic..around 150.00..have fun
