I had an issue where fedora was not detecting my headphone when connecting to the front headphone jack, I only heard a noise from the headphone, but no audio. I was able to fix this by adding options snd-hda-intel model=,no-front-hp to /etc/modprobe.d/alsa-base.conf, but the noise is still there.
It’s hard to tell if it’s something to do with the system or if it’s a hardware issue, but does anyone have any hints as to what the problem might be?
Is your headphone just that, or is it headphone with mic?
I think you probably have two jacks on the front of your pc, one for headphone and one for mic. A headphone with mic that has only one plug on the cord (4 barrel) is not compatible with a jack that is headphone only (3 barrel).
The difference is seen by the number of barrels on the plug. A headphone with mic will usually have either 2 plugs (one 3 barrel and one 2 barrel) or one plug with 4 barrels. A headphone without the mic will only have 3 barrels on the plug.
I have both, a headset with a mic and only one plug, and a headphone without a mic. Both have this noise. And I only hear noise when I play some audio or when I open the audio section in the gnome settings, when I stop the audio or close the gnome settings, the noise goes away after a while.
The problem seems to be on the front panel itself. I was trying to transfer something to a flash drive and noticed that every time I wrote something to it it interfered with the noise I was hearing, so I unplugged the flash drive and a wireless USB mouse I had connected to the front panel and the noise stopped.
I installed windows in dual boot to see if I would have the same problem and the noise was there every time I plugged anything but my headphone into the front panel, so its not a GNU/Linux issue, it seems to be a hardware issue.
Ah, so is this a desktop? if so then it is quite possible there is a short between wires to the headphone & USB on the panel. That can often be fixed with a little bit of patience in opening the system and tracing wires. Especially looking closely at the panel connectors themselves where it is most likely the wires are very close. If they are really close or touching then simply using something small like a knife point or toothpick to separate the wires/connectors should fix that.

Front panel connectors commonly do this, especially if you have USB 3.0. USB 3 creates a lot of electromagnetic interference if the cable isn’t shielded well, and most front panel cables are cheap and aren’t shielded well at all.
