I am experiencing low volume output from my RPI 3B running the latest version of Runeaudio. When I first installed the image about a month ago I would listen comfortably at about 25% volume on my stereo system. After correcting a channel swapping issue I reinstalled the image and now the volume output is such that the stereo has to be at roughly at 75% for decent volume. Important to note the setup is RPI3B, 16gb SD card, Dac+, into Sunfire Preamp, then two Carver Amps. If I connect Chromecast or any other device volume output is very strong. I've read some posts back from 2014 but can't imagine that fix would be relevant today. So what am I missing?
Thoughts?
Thanks,
Allen
