Nintendo Switch is buzzing on the pc?

I connected my Nintendo Switch to the PC, but the sound makes a loud buzzing sound. Some games have louder or quieter hum. Can I do something against the hum, maybe buy speakers?

And how did you connect it to the PC?

How to connect it to the TV. Question: Can I add speakers to the Pc, even if the Nintendo Ssitch is connected?

Is there any other way than via the docking point of the USB-C port?

Ie you have the HDMI cable from the dock to the HDMI input from the PC (graphics card or motherboard?) connected…

and what do you expect from it? These are not HDMI inputs

I connected it to the monitor.

No… HDMI can only be output via the dock if an extra power supply is connected. In addition, you should only use the official dock…
