Yep, T2P design with hybrid digital/analog multi-function knob.
Our official firmware will only control the headphone volume of headphone jacks and line our with fixed out.
And it’s still possible for knob to control the output of line out via adjusting the volume register of ES9038Q2M DAC. And in that case, there will be two types volumes:
- DAC volume(digital) for both LINE OUT and Headphone Jacks
- Hardware volume(analog) for Headphone Jacks only
But we think two volumes will be too much complex for most users, so we just disable the keep the DAC volume as MAX(highest performance), and only keep the hardware volume for Headphone Jacks.
We might release dedicated firmware to support the DAC volume for line out for specific users in the future in needed.
Good day!
