I would like to get Hardware Volume control working in the latest Volumio using the Khadas Tone Board. I can see the functionality was added with Tone Board firmware V1.04 which I have, and I can see reports that it was working ok. But also reports that since at approx V2.657 of Volumio this isn’t possible any more.
I have Volumio 2.777 on rpi4 with the Tone Board over USB3 and I can’t see ‘Hardware’ as an option for volume control - only ‘software’ and ‘none’
But I can’t use software volume as I am using the DRC plugin.
Does anyone have any ideas or suggestions?
