I have currently a "DF mini player" that is connected to an XH-M543 amplifier over the DAC gpios.
I have another project with A2DP that is connected to an external decoder board (see picture below) and is also connected to a separate XH-M543 and that works to. (LGR is connected)
Now my question is... Can I connect those two sources to one amplifier with only one esp32? I prefer to keep this amplifier. I could wire them together i think... Do I need a DC blocking cap and a voltage divider to do that. Or are there other, better ways to do that?
