Hi, I’m newbie in the world of sound processing so I might not know even basics. I’m sorry, I didn’t find this problem described here so I’m posting it.
I installed newest Volumio on RPi3 and added HiFiBerry DAC+ and official display. Now I am able to output audio through DAC and additional USB creative soundblaster. It works when I use regular PC speakers, bluetooth speaker (using jack cable). But if I plug it to stereo system (Yamaha crx-040) audio quality is terrible, both from DAC and Soundblaster, even RPI3 jack. This may sound like hardware issue but previously I used RuneAudio in this configuration and it worked just fine. Rune lacks Youtube support like in volumio though.
What can I do to fix that audio quality? Volumio has some audio settings, but I don’t know which one to choose.
