You can find the instructions to revert to the stock firmware here in biktorgj's repo.
Edit: You can also try switching out just the ADSP firmware as mentioned here. You are probably on 01.003, stock is 01.002. That's the closed source part which I think is more likely to be responsible for problems than the open source part of the custom firmware.
