This is getting extremely frustrating. People most of the time can not hear me, yet i can hear them perfectly. I had recently rooted and flashed CM6 on my hero, and i had not been experiencing any problems. I flashed a new radio, uncapped kernel, a nightly build, no problems. Then one day people are not able to hear me during some of my phone calls. I would be on the phone with one person, perfectly fine, and then hang up, 20 minutes later get a call from someone, they cant. I would re-flash the custom rom, re-flash the same then different radios, but it seems to have been progressively getting worse. Last night i ran an RUU update, completely wiped everything. Rooted, installed CM6 and nothing else, tried making a call to no success. My next step i guess is to run an RUU update wiping everything completely and try without a custom rom, but i dont think its the custom roms fault. Any suggestions?
