Ultimate RGB/Audio cable for turboR

Over the years, I think the way turboR mixes PSG/SCC/MSX-Music has more or less become the standard of how things should sound on MSX. So, for an MSX musician a turboR with SCC and Music Module is more or less an ideal setup - if only it could be connected to a home stereo.

Of course, you can alter the RGB cable to connect the audio out to a cinch cable, but as you all probably know the turboR (and many other computers) produce a lot - and I mean an awful lot - of background noise.

My question is simple, but I fear the solution might be very hard. How do I eliminate this background noise completely (or as much as possible) without butchering the sounds of the PSG/MSX-Music/SCC? Can it be done with something as simple as a resistor/capacitor, should I get the ground signal from something other-than-the-MSX or do I need to get a hardware tech guy to adjust things directly on the motherboard of the turboR?

Has anyone every tried to accomplish something like this? Is it even possible?

It's a thing in your computer: clicky

Maybe some hardware expert would like to sell a service of fixing this?

Ah, it's good to see that I'm not the only one bothered by this. Question that remains is

- How should I (let someone) reroute the +5V/GND stuff inside a turboR (GT)
- Has anyone ever actually done this? Were the results satisfactory?

As for those "but you can easily use an emulator!" ppl I can only say "Yeah, but I really want to do it on a real MSX!" ^_^.

The most important thing is that you don't connect ground to Audio ground in DIN8 (pin 1) but connect it to the shield of DIN8. The audio ground pin is bad on MSX tR.

...and doing so will make the sound 'better but not perfect'?
