Hi Kent,
I have the PDF manual of the M100, it's not helpful in the least. There is a selection button. It has optical, coaxial and USB in and when using it with moOde I have always selected the correct inline. But the M100 is a bit odd, it has 2 USB in for 5V, but only one is marked as an input.
So, I did what you asked. I hooked the M100 up to the external power supply and to a different output, specifically optical from a Chromecast Audio powered by a backup-battery. Which is then in turn hooked up to my powered computer speakers. I set up the CCA, and everything worked. So, it looks like it is a bum USB input on the M100. I may have broken it somehow, because this is actually the first time I have used it.
The CCA DAC is no slouch. But I need RCA out because my receiver and CD don't have coaxial or optical in. I also have a about 1TB of FLAC files, and nothing on Android will handle that library efficiently or responsively. I found moOde.
I did try the bare RPi 4 with the M100 and still got:
I don't think I am wrong in assuming I need a new DAC, at least for the purposes I need.
It's looks like a Topping D50 with my RPi 4 would fit the bill.
Any insights?
