Hardware Mixer Volume Control

[jimbiggins]

First, a thank you: Snapcast is awesome and I've found it to be extremely stable and efficient. Thanks for the effort to build and maintain these projects.

The Android app doesn't seem to have the ability to control the hardware mixer volume level. It would be great if there was a way to do that. My application is a "headless" install of the Snapdroid app running in the background of an Android tablet operating as a kiosk. To make a long story short, I need other Snapcast clients and the local user interacting with the kiosk app on the foreground to be able to change the volume of this device. The Snapdroid app only changes a software mixer volume and local commands from the kiosk user to the hardware mixer are fighting each other. The kiosk users cannot interact directly with the Snapdroid app on the Android device. I need one volume control which I believe would have to be the hardware mixer so the hardware volume controls on the kiosk hardware control the sound properly. Am I missing something or is this the way it is supposed to operate?

I'm running V0.28.0.2 on Android 13.

Thanks!
