Hello
The Raspberry PWM features 2 PWM Channels (PWM0_0 & PWM0_1). These can be remapped to be used as Audio with the help of audremap overlay. (with some additional HW filtering)
Now I have a use case where PWM0_0 is already in use for a backlight PWM circuit.
It would be very nice to now just use PWM0_1 alone as single channel mono Audio. Is this possible? I just see pair wise stereo operation in the audremap overlay parameters.
Or is this a use-case where I'm better off with an external MAX98357 I2S Amp?
