It may be worth trying the system outside the case.

Bad grounding can cause audio interference too, if you don't have any of the
board's grounded mounting holes making contact with the case it could be causing
issues. I have seen this with some cases that use anodized/painted standoffs.
The same applies to the power supply itself, if it isn't grounded to the case
it may cause interference. Now that I am thinking about it, maybe also check to
make sure your actual power outlet is properly grounded and that your power cable
is grounding correctly too.

I have built more than a few audio workstations over the years, in almost every
instance I had interference issues it turned out to be either a bad ground or
a noisy (electrically) PSU.

It shouldn't be caused by the board itself as it has an isolated portion of the PCB
dedicated to audio explicitly to prevent noise/sound contamination. If it is
happening with the built in audio then it's highly unlikely to be the USB ports
as the sound portion of the board is physically isolated and shielded from the
rest of the board. ]]> Wed, 03 Jun 2026 05:11:13 +0000 https://forum.asrock.com/forum_posts.asp?TID=113529&PID=201587&title=audio-interference-with-the-b860l-wifi#201587 https://forum.asrock.com/forum_posts.asp?TID=113529&PID=201585&title=audio-interference-with-the-b860l-wifi#201585 Author: Juergen

Severe Audio Interference with the B860L WIFI Motherboard

My B860L motherboard, paired with a Core Ultra 5-235 processor, is producing severe interference noise at the audio output. The noise intensifies when the processor is under load?”for instance, when a program is launched or the mouse is moved.
I have tried several different ATX power supplies, but the noise persists.
I also tested two separate sound cards as an alternative to the motherboard's integrated audio output; it appears the interference is being transmitted via USB.
This situation is particularly frustrating, as I use this PC for music production.
Is the motherboard defective? Or is this a design flaw?]]> Wed, 03 Jun 2026 03:22:34 +0000 https://forum.asrock.com/forum_posts.asp?TID=113529&PID=201585&title=audio-interference-with-the-b860l-wifi#201585
