Z370 Taichi - EMI From GPU heard in Headphones

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I've got a Z370 Taichi running with an i7 8700k and an EVGA Geforce GTX 1080 TI.  The power supply is a high quality "Seasonic 1050".  Today I plugged in a pair of Audio Technica ATH-A900 headphones (fairly expensive high end headphones) into the green "Line Out" port on the back of the motherboard.  The result was less than ideal.  I could hear my graphics card.  If I move the mouse, I'd hear a tiny "shhhhh / eeee" noise.  If I drag windows around, same thing.  Anything graphical that occurs on screen makes a noise.  Even if I didn't interact with the machine in any way I could still hear a fuzzy background noise.
Some googling suggested that this is caused by electro-magnetic interference (EMI) from the graphics card getting into the sound system on the motherboard.  Is there anything I can do to correct this?  Because in it's current state I can't stand it.  The motherboard advertises high end audio with gold components, shielding, high signal / noise ratio, etc, but it seems mine isn't delivering on that.

Thanks,

Jonny K

	I recently built a new rig and have been experiencing similar issues as you describe. Build: i5-8600k Asrock Z370 Fatality Gaming K6 EVGA FTW2 1080 Seasonic Focus Plus 650W I first noticed noise coming through my headset the other night while playing PUBG. It almost sounded like an RC car and both the in/out (green/pink) on the back of the motherboard were picking this noise up, as my friends were also able to hear this buzz via Discord. This noise was more noticeable in-game while my video card was under load. When going back to the main menu of a game, the noise would almost disappear... Although I could also hear a slight "eeee" noise as you describe when sliding windows (i.e. a browser for example) around on my screen. I would also like to know of a possible solution. Thank you, Kubie Note: If I do find a solution else where, I will post it here as we are having a similar problem.

	bumping this from ages ago to agree. hopefully these are bad boards and not a problem with the entire line (typing this out with a z390 machine)

	This problem never was resolved, sadly. I normally wouldn't care so much about on-board sound, but ASRock advertised about how amazing it was supposed to be so that's exactly what I expected. It was not amazing.

	I have the same issue, literally people in discord were saying that every time I spoke it buzzed. I just moved my headset to the front jacks and it works perfectly. I'm not happy about this but it did resolve the issue. Seems to me that if this is the case, then something is not properly insulated.
