INFORMATION:
The JBL LSR305s make great PC speakers, zero noise, except when
playing a flight simulator (X-Plane).
Tried two different video cards, PNY GTX980 and MSI GTX960.
Tried built-in audio and Creative Rx soundcard
Tried a different speaker cable.
The noise corresponds to what is displayed on the screen. It
changes when a menu choice is selected. Sounds like an oscillator.
You may need one or both of: a bigger psu in the pc and a set of inline
insulation transformers that keep pc's ground and audio playback systems
grounds separate.
Neither of my monitors have an HDMI audio output jack.
QUESTIONS:
Should I try an HDMI pass-through with audio extractor?
No, I don't think it is gonna save your day, I think, but I do not know
this, that the supply voltage(s) in the pc are modulated because of the
videocards current requirements.
Kind regards
