Motherboard to front panel connections

Guest · Sep 19, 2015

Hi. So I recently migrated my dell xps 8700 to a phanteks enthoo pro. And I connected my front panel into the 11 pin I/0 slot right below where the gpu goes. I connected it the same way you would a 9 pin slot but I keep getting a buzzing nose when I plug my headphones into the output Jack. Did I plug my audio leads to the wrong pins? If so how do I do it properly? (There are no diagrams on Google)

you plugged front audio into number 23?

No, each cable connecting to the front panel is only 1 pin wide. I assume I have to group them together but idk where to do that.

you mean the power,reset,hdd led etc cables

if so number 15 on that diagram but will have to look really closely at the board to see where each one goes

Yeah. I just assumed that the audio jacks go with it. I also assumed it went into 18 since that was labeled "f_panel"

sorry 15 was a typo doing too many things at once--18 for power,reset,hdd led etc cables

23 for audio

So theoretically, the buzzing would stop if I moved my audio jack connection to 23? That's the only problem I have.

should do 23 definitely says F_AUDIO1

mcnumpty23 :

Ok I had it wrong. The audio cable was going to slot 23 the whole time.

sorry. But the buzzing still occurs. I tried lowering the audio quality. But that doesn't help. I've read that installing a dedicated sound card helps. Thoughts?

mcnumpty23 · Sep 20, 2015

does it buzz if you use the rear audio jack?

Guest · Sep 20, 2015

mcnumpty23 :

Those don't work at all.

mcnumpty23 · Sep 20, 2015

not having much luck are you

did the rear audio work before putting it in the new case?

Guest · Sep 20, 2015

mcnumpty23 :

I never used them before. I never had a need to.

not familiar with dells but other than getting a sound card

only other thing i can think of look in the bios for a disable onboard sound option

vaguely recall some older pc bios having something like that

if there is one make sure onboard audio is enabled

I'm not at home but I'll try that. Remind me how to enter the bios again? I've only done it once.

different for each maker usually press del or F1 or F2 when pc is starting

Guest · Sep 20, 2015

mcnumpty23 :

Everything is on and still no change. How does a dedicated sound card cancel the buzzing? I read that it does but how does it work?

mcnumpty23 · Sep 21, 2015

because it by passes the built in audio i presume

like when i plug in my sound bar to my tv the tv speakers no longer work

Guest · Sep 21, 2015

mcnumpty23 :

Gotcha. I'm also getting a headphone extender to reach the back panel. Isolating the cord to the sound port hasn't worked. Isolating any devices that cause magnetic interference didn't work. I have wireless headphones but they can be choppy and cut out sometimes. :
