Line IN - Remove audio noise?

I have had noise on my Line IN audio input for years that is not coming from the microphone or anything.
My old PC (then 1000 euro) and my current PC (3500 euro) both have the noise. My cheap laptop from what do I know from which century has no piece of noise and everything runs perfectly.

Maybe it has to do with grounding? I really felt like I've tried everything. Restart Windows, install drivers, uninstall and so on.
The noise is always there. No matter whether something is connected to the cable or just loose. But as I said, it's not the cable / mixer / micro or anything.

Maybe the sound card is no good? Thinking about an audio interface?

The old laptop still had a hi-fi input, today's developers do without it. Probably on it.

Z270 GAMING M3 is my motherboard and therefore my pseudo sound card.
Yamaha MGP12X is my mixer that has a USB port for IPods (according to text). So is it an audio interface or does it have one built in?

Dr

Does not seem to contain an audio interface. I suggest an interface from 88 euro at Thomann. From there the interfaces start with decent ASIO drivers.

Dr

I could also imagine that.

Pa

Order me now the "Focusrite Scarlett Solo 3rd Gen" which has an ASIO driver. Thank you for the recommendation. Will let you know if that solved my problem.

Dr

Solo is not a good thing. You can only add mono, not stereo. That is why it is called SOLO.

Dr

Not quite true. Is already 2-channel. But difficult to connect… One XLR and one jack.

Pa

I was going to say ^^ But why connect poorly, I have my mixer and then simply an XLR cable from the stereo output from the mixer to the MIC / LINE interface

Dr

But as I said, actually mono.

Pa

Yes, I also notice right now. I would then get the 4i4 version. Would the audio interface reduce my latency or almost completely eliminate it? At the moment I can clearly hear the delay with my PC mainboard sound card, even with few samples.

Dr

In any case, the latency would be very low. But it doesn't go away completely.

The lower buffer size means lower latency but at some point you will get errors. You have to test it.

Pa

The interface is now there, I have connected it and now I have no more noise.
