Sound Issue

[fuego3048]

Hey everyone, hopefully someone has an answer to this one. On my 6700 I was talking with someone on the phone and then randomly they couldn't hear me anymore. My sound on the phone doesn't work at all unless someone calls me, even then I can only hear the ringtone. I answer the phone and nothing. I was using a wm6 rom at the time so I flashed stock verizon 2.XX aku and that did nothing. I then tried the latest stock rom 3.3 and that still did nothing. Any ideas? I really don't want to have to get another phone.
