Solved: Hardware volume control on Topping D10

@Tim Curtis

Ah, yes, the trailing space!

I don't know the details of the Topping D10, but as described on the Topping website, there's more than a passing similarity in system design to that of the Khadas Tone Board I have. 

In particular, they both use the XMOS XU208 to implement the USB-to-I2S interface. I wouldn't be surprised if their XMOS firmware was based on the same understanding of some XMOS "reference" code or even if the writer of the first (likely Topping) implementation was then hired to write the second.

Just a random musing over first cup of coffee for the day.

Regards,
Kent
