I was wanting to use an Explorer pHat and Speaker pHat on a Rover project but it looks like there is a conflict.

https://pinout.xyz/pinout/speaker_phat# On the SPKR BCM 19 (I2S) and BCM 21 (I2S)
If disabling the Speaker pHat VU meter will fix it I’m cool with that. My plan was to use the Mini Black hat hac3r kit to mount the two side by side.
