I dont know if its a Hardware or Software problem but I cannot be heard in the Pal Talk chat rooms.
I can hear others speak and play music and if I blow into the Mic, I can hear me alright.

I have never quite worked out how to play music through the Computer but instead put the Mic in front of the speaker and did it that way but I havent done that since Yahoo closed its Chat Rooms down 4 years ago.

I dont have skype or anything like that which probably woulnt work anyway.
