PeppyMeter and moOde

[zandr]

I've just set up a new Moode instance for music in my home office, running 8.3.7 on:
RPiOS: 11.8 Bullseye 64-bit | Linux: 6.1.21 64-bit
Model: Pi-4B 4GB
Audio: HiFiBerry Amp2

I've followed @fdealexa's excellent guide at least as far as running PeppyMeter from a shell prompt. Everything is working great from MPD, but it appears that when using the AirPlay renderer, the signal that is seen by PeppyMeter is much, much lower than when using MPD. I suspect this has to do with the way Airplay manages hardware volume control. The Amp2 is configured to use hardware volume control.

It's not a huge deal, but I use AirPlay a lot, so if there's a way to configure the airplay renderer differently, I'd like to do that. Any advice?

Thanks for all the great work on Moode and the docs on installing PeppyMeter on a Moode box!
