New Z87 Mobo - Hissing Sound? Advice please

post #1 of 4
Thread Starter 
Hi Guys,

I need some help please.

I just purchased the MSI Z87 GD65 + 4770k and have hissing in my headphones.

I have installed the correct realtek drivers and have Roccat Kave 5.1 headphones correctly plugged in but there is a faint but audible hissing noise in both ears.

Has anyone had similar experience? what could this be caused by
Is this maybe static from the Mobo?
Is there any way to remove it without going for a new discreet soundcard?
If not, are any of the following cards any good (these are in stock at my local computer store):

By the way for those that are interested, I got my 4770k to 4.4Ghz stable at 1.225V. Max temps are 79-81c with my pump running at it's slowest speeds. Not impressed with the OC potential thus far but the chip sure is faster than my old D920 smile.gif I would like to get it to 4.7 and will need to experiment with increased voltage when I've sorted the sound out.
Also got my fairly cheap ram to 2000 mhz CL9, haven't tried any faster but will do soon.

Any help will be greatly appreciated guys biggrin.gif

Which port are you connecting your headphones into? Speaker? Keyboard with LEDs? I/O Panel? Front header?

I have my headphones connected to the IO ports. The headphones come with 4 x Jacks and 1 x USB for Mic. I've got them matched by colour and when I do the 5.1 test the headphones produce the correct direction of audio.

FYI, the hissing didnt exist on my old setup (sigrig)

It might be the motherboard producing the hiss. From what I know, having a wireless mouse USB dongle in the back of the I/O panel produced a hissing noise. When I received my new LED-backlit keyboard with integrated USB and audio and mic jacks, I replaced that mouse with a wired one. The hissing went away, temporarily.

The hissing came back, whenever I connected my headphones to my audio jack through the keyboard. I found out that the components controlling the LED programming was causing the hissing (I found out when i set my LEDs to flash mode).
