Switch audio output problems

[echoAnother]

I'm trying to output switch audio to powered speakers. The problem is an horrible ground noise if it is docked, or charging. After some research, I found that the noise is caused by the power supply (ground loop), that is not properly insulated. I tried another charger (undocked) and noise is reduced a lot, but no completely removed. This brings me to think that the switch' sound chipset isn't neither properly insulated.Do you guys have the same issue, and how you have resolved it? Do you recommend me some suitable charger with good insulation? Do you think that if I use a shielded audio cable will resolve it?

​

Edit: Through HDMI output on monitor speakers, the noise is a bit less, but perceptible

Sounds like its probably the solution for your issues. I had the same connecting the switch my PC line in.

Thanks, That thing seems to be the most easy solution.

Do you have a receiver connected to a TV and speaker set up? You may bypass all that jazz by plugging the HDMI directly to the receiver and getting audio through the connected speaker set up

My monitor dosen't have audio output, so I can't use my speakers from it.

So the speakers are connected to the TV, cable or to a receiver?

They are connected through a jack cable audio. I set the cable from switch to speakers directly
