Can the Mono example use only DAC_CHANNEL_2 and pin 26, since pin 25 is composite video? #8

I noticed that the Mono example uses pin 25 and it initializes both channels, which makes this sound driver incompatible with the approach to untie the two DACs and use one for composite video, the other for audio. However from the video I was left with the impression that the ULP approach was a way for the sound not to be interrupt-driven and offload some of the work to the ULP.

Can that Mono example be modified to use pin 26 instead of 25 and leave the composite video channel unaffected?
