I've been using this combo (HiFiBerry Amp2 mounted to a RPi 3A+), running with piCorePlayer, for about 15 months, with no problems whatever. The power supply (fed to the AMP2) is 20V/6A.
A couple of days ago I had to adjust some wiring, and so I had removed the boards from the box they live in, and handled them a bit. (The Pi lives in a ventilated box on the floor behind the speakers.)
The next time I used it, and ever since, playback has been at half speed. I tried reconfiguring pCP to use the headphone jack, and audio works fine in that case. when I configure back to "HiFiBerry DAC+ (and Pro, AMP2)", I'm back to half speed again. I've examined both boards (using a loupe) for damaged/missing components.
Is there any sort of config setting I should be checking? I've run through all of the various update steps in the web UI, just in case.
I'd really rather not have to shell out another $60 to $80 for a new AMP+ board. :(
