The "hissing" is clearly audible on my Major III, but when using my DT770 Pro headphones (which have considerably higher impedance) the hissing noise is low enough so that it cannot be heard. This is of course no ideal solution, as it is rather an inconvenience, but for now it works.
From a circuitry viewpoint, it might be a possibility that there's some sort of interference (the audio is being affected by the constant electrical signals on the board), which would go along with my initial observations that the hissing is most noticeable when the machine is under some considerable load (i.e. YouTube videos...). So maybe shielding could help with that, right?
Maybe there will be a nifty software solution to this...
I got some traction on this!
1) From the command line, run pavucontrol
2) Click on the "Output Devices" tab.
3) Where it says port, change from "speaker" to "headphone"
That seems to be enough - the sound is much louder and more clear.
