Default [Q] No Sound after 4.4.2 install

So my ATT S3 has completely lost sound. I updated the bootloader to the latest 4.3 leak, the modem, and then I installed a 4.4.2 rom (currently on OMNI, but I've gone flash happy the past few days trying to fix the sound, no chance).

I can't downgrade my bootloader, and for some reason ODIN is not working for me. Am I missing something?
