I have an older 2013 Dell Optiplex 3010 computer, running Ubuntu Linux 20.04. the built in DAC sounds really good. I am shocked actually. Says it’s an Intel HDA 6 Series/C200 Chipset Family High Definition Audio Controller .
Once I got the internal speaker routed correctly, the simple line out on the back of the computer, not the headphone, it sounded great. How is this possible? It’s really as good as my Schiit Modi, how can this be? Maybe I am hallucinating?
