I have a HifiBerry DAC + (RCA) purchased end of June, paired with a Raspberry Pi 3 B+ purchased in May. I'm using Volumio 2.806 and primarily using it as an AirPlay receiver. It worked fine for several months.
One of the channels has been dropping out. It varies from distorted to just gone.
Here's what I've done to troubleshoot:
If I disable the DAC and use the headphone out, it works fine.
I reflashed a new SD card with a fresh install of Volumio; the problem still happens.
It seems like the board might be toast. Any suggestions?
