Pinpointing cause of noise problems on Node 304 Chassis audio output

post #1 of 24
Thread Starter 
Hello.

My new rig has problems when using the audio output of the front panel. I experience horrible noises (interference?), especially when moving the mouse pointer.

Things I've already tried:
- happens with different headphones
- when using the output on the motherboard it works fine
- this on is interesting: the problem only occurs if the usb (2.0 or 3.0) from the front panel is connected to the motherboard
- reseated the cables and checked that they are not loose
- happens in Win 8 x64 with newest drivers and also in Linux
- tested without dedicated GPU and without the front panel LEDs

FRACTAL DESIGN NODE 304 M-ITX BLACK
Asus P8H77-I
SAMSUNG 840 SERIES 250GB SSD SATA/600 TLC
Silverstone Strider 550W Silent Modular 80 Plus Gold
Intel Core i5-3570K Ivy Bridge - Box
Corsair 16GB DDR3 1600MHz (2x8)Vengeance

Have read other people having problems with the front panel of their chassis (something along the line of grounding issues on the circuit board or bad quality on the cable shielding).

What do you guys think?

Sounds like broken ground/shield to me.

Do you mean on the chassis?

Cause I have gotten in touch with the reseller who recommends getting a replacement for the front panel. I'm not able to test the chassis or motherboard separately.

This might be the PSU do u have another one to hook up?

If it is a pitch noise, especially when moving the mouse it is electrical (cpu) intereference over the bus of the mb

It can be really anything but big chance it is the PSU.

If u have one u can Always try

I was able to test with another PSU today, but no luck.

Seems they will be sending a replacement part for the chassis. And when I get the replacement it probably turns out it's the motherboard ...

I just tested and it did not work with a new replacement part for the front panel!

So it now seems it must be something wrong with the actual motherboard. I assume it's not likely to be caused by the cpu or ram chip.

Quite interestingly I got the feeling when receiving the motherboard that they had sent me a demo product. If this is true I was not told of this and don't think it's appropriate?

Well, the new motherboard didn't work either, so I have no clue what to do now. Any ideas what the problem is?

You are not alone on this. I saw this thread and did some testing. When I am using a USB device on the front ports there is a noticeable whine that takes place. When I have music turned up the whine is not awful, I can barely hear it but if there is no music it is quite clear. I have tested with the front ports hooked to USB 2 and USB 3 on the motherboard and the same effect is taking place. There is no issue when I use the rear port.

My gut reaction is that this is from a poor design on the front header and there not being enough shielding between the jacks and the ports.

I'm with both of you. I have some static noises. When I move my mouse around it get's noticeably worst.

Is your mouse on the front USB ports? Also is this when using the front headset jacks?? Sorry if dumb question but it is not common for me to hear of someone using the front USB for a mouse.
