[Q] Bad radio - can't track down the answer topic

Hi everyone, hope someone can point me in the right direction. Flashed OmniROM on an HTC desire (bravo) and it's working great. Only problem is when making a call, no sound comes out of the earpiece. If I put it on speaker phone it's fine, and apparently when it's not on speakerphone the mic works fine, people can hear me on the other end, but I can't hear a thing. Suspect the radio is the problem here so need advice on which radio to use (especially for internet use too) and how to install it. I have Ext4 bootloader installed too. This is my interim phone after my Samsung Galaxy S2 died completely (will not power up since it died during normal operation), which looks like it would need a JTAG burn to fix, right after I successfully replace the USB board. Anyway, any help appreciated. Thank you.
