While waiting for my DAC to arrive I connected my RPi2 to the Amp with the mini-jack.
This has worked fine for some weeks. But now, for unrelated reasons, I had to reinstall the system fresh.
And now the volume of the mini-jack is suddenly extremely low. I have to put the Amp volume up to 70% to hear that there is indeed some kind of music playing. Where normally 20-30% is enough. Also what I then hear is appalling; lots of noise and cracks.
I played a little with the playback settings; but to no avail.
Also I tested the cable and the amp with another device, and they seem to be just fine.
Any tips anyone?
