Hi!
I'm running moOde on a rpi zero w with hifiberry's miniamp which i integrated in an old bluetooth speaker (gutted the original internals) but i've run into an issue.
When the playback is stopped there's a low frequency hum on the speaker. Could this be because the miniamp stays turned on? Is there a way to add a function to moOde that when the playback stops it then turns off or mutes the power stage of the miniamp?
In the miniamp documentation there's a note that GPIO16 can be used to mute the power stage and GPIO26 can shut down the power stage completely but i have no idea how to add this or which config i would need to edit.
Thanks
