headset mic problem

[dualshift]

Has anyone ever encountered a headset mic problem? Using the dongle that came with the TP, and trying 2.5, 3.5 and the original usb headset HTC bundled with the TP, no one can hear me through the mic.

I actually had a more general problem where the internal speaker was busted as well. I went to sprint and told them about the two problems. They replaced my entire screen section which fixed the speaker(great cs), but it looks like the headset problem is still there.

I'm just wondering if its more likely to be a busted usb port, or a busted dongle. I can still start a data connection..
