Noise when connecting with PC?

Eve,

I connected my computer to an older system. This is a loud noise, which partially exceeds the system sound. The problem is that this was not the case with any other source device, neither my phone nor my laptop. The PC has a Realtek ALC892 Sounchip and the system is connected via the rear jack connection. My question is therefore whether it is a hardware or a software-related problem and how can I solve this.

Noise is an irregular process (e.g., in transistors). You can't eliminate them.
Your "older system" produces this. Possibly there's the gain of the power amp set too high, so that what is rushing forward, is highly amplified.

As previously mentioned, this only occurs in conjunction with my PC. Why is there no perceptible background noise on my laptop or mobile phone while my PC immediately buzzes?

Look at the pc volume is not set so high that may or may not be the cause

Whirring is no noise! Now that sounds like disturbances coming from outside. Bad ground connection…
