I am running an Amp2 on a RPi 4 with Q Acoustics 3020i. Everything was working nicely until I switched from Moode to Volumio. On the first startup, somehow the volume was set to 100. After turning it down, the sound is terrible. Sounds all distorted and fuzzy. Am wondering if I have blown the unit. I do notice that whenever I plug the power in, I get a number of sparks, but that has always happened.
Any ideas, or do I need to order a new one :-(
