I'm having Some trouble with my microphone, When I record or talk to someone Voip there is a really high pitched noise and the speech comes out kind pf jumbled. Its just a cheap mic and I think it has a few years on it. So...It could be that. It is hooked into the back panel and the front panel is muted. It almost sounds like feed back, but no matter where it is it doesn't matter. If anyone can help...thanks, Phil.
