Default Digital noise from speakers in flight simulator (X-Plane)

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.

Neither of my monitors have an HDMI audio output jack.

QUESTIONS:

Should I try an HDMI pass-through with audio extractor?

The soundcard has SPDIF output. But I am having trouble finding an
inexpensive SPDIF input preamp for the powered speakers.

Thanks.





Could you solve the problem by now?


Just out of curiosity, I searched in Duckduckgo.com

video card dac audio interference

you might want to do the same and check out some of the resulting pages,
e.g.

Somebody mentions having solved it by removing software (Dolby stuff),
or updating drivers, somebody mentions unplugging a cable from the aux
input they were not using...

BTW you didn't mention what motherboard it is.

And... I think I've gone through each post in this thread but now,
sorry, I don't remember: could you check out the SPDIF output eventually?
