[SOLVED] USB DAC Issue or Install Issue?

[radiooff]

@radiooff
The M100 has two usb ports, one for power and one for source input.
You are connecting the right USB port to your Pi aren't you?

Yes, I have.

But, it's certainly possible I could have damaged the input port by accidentally plugging in the power supply to it; if that is possible. So, now I wait for the new DAC and power supply.

You shouldn't have any issues plugging a psu into the input as it's input/power anyway. The only reason there's a separate power input is it the device you're plugged into can't supply enough juice to the DAC.
You could try enabling 'USB UCA2 fix' to get a little extra power into your DAC.
I've got an SMSL Sanskritt 10th II and had no issues at all get to g it to work on a Pi3.

Thank you. I have tried that USB fix. It helped me getting my USB hard drive recognized, but not the M100.

This journey has been a bit strange.

I've tried using an RPi3B+. When I use that I can pick between 32bit and the experimental 64bit build. I can specifically enable Bluetooth and Wi-Fi. Whereas, on The RPi 4, I can only pick the 32bit build, not the 64bit one. BT/WiFi are not itemized in the same way as on the Pi3.

I do have the Topping D50 and the power supply for it. I'll rewrite the build and try installing from there.
