That is config option already. Did you set value? If yes, then there is driver bug. If not, then add value.
demod_write(4d, [91]) demod_write(4d, [91]) no demod_write(56, [00]) YES
driver bug

Two clear driver bugs, 1 case unclear and the rest should be programmed earlier.
So hard code those bugs, if you already didn't, 0x33=0x99, 0x56=0x00, 0xfd=0x46 and make test. Do that same to find out all buggy registers until it performs as it should.
