Muse Proto: Simple Speaker, unable to set volume

Darkguinito · January 22, 2023, 7:41pm

Hello ,

First, @Raspiaudio team, your work is ( )

I try to use ESP MUSE proto with espressif framework. I gather some code from your various examples using arduino framework and also from squeezelight repository but i can’t figure out how to set volume up.

I try to make this example as simple as possible, it come from espressif get-started package.
I simply add (from espressif template) a custom board matching ESP Muse proto specification from informations i gather in various example.

Everything is working smooth, except than i can’t set volume level.
Following, the source code example, working with espressif esp-adf-v2.4

Can someone help me ?
Thanks for any help!

Hello and thank you for your encouragement !

Muse Proto volume should be controlled by software, so it is really depending on the library you are using but all of them have usually volume for example look at this old example for Proto :

or this one that is the Mn Cast but is more up to date and uses the same volume control :
