Looks like it is working, but I can't hear output, i think the AKM code needs to be modified to enable FM output

Typo ?

Are you sure YH820 and YH925 have a FM Tuner?

Thanks for the typo. I fixed that.

I am not sure but i have seen several texts that talked about fm support for all yh devices. But i am not sure if all devices got that.
