Hello, I'm now a proud owner of the X470 Taichi. The only thing that annoys me is that I'm hearing EMI in my headphones. Doesn't matter if plugged-in in the front or rear. Is there anything I can do? What I can tell is that the GPU is causing this if it gets load. Would a PCIe risercable to vertical mount the GPU help? Or would a external Soundcard like the ASUS Xonar U7 MKII a better deal? Would like to hear some ideas from you guys. |

What audio drivers are you using? X370 Taichi should have identical audio solution, I never hear any noise from the rear output, and only some slight hiss through front output in my very sensitive IEMs. I'm using default MS drivers on Windows 10 1903. -------------

I'm using the one that are provided by ASRock on the Support page of the X470 Taichi. I also contacted asrock via facebook and they told me that this shouldn't happen and I should contact the support which i already did. |

I'm suggesting you to remove that driver and see if the issue is still there. After installing Windows 10 1903 I found that default MS drivers work perfectly fine and I don't need to lurk for new Realtek drivers somewhere, unless you need both front and rear audio outputs to work at the same time through Realtek control panel. I tried X470 Taichi drivers from ASRock page on my X370 board because they were more recent, and I had issues with sound. -------------

By "at the same time" I mean as 2 identical outputs. MS drivers still provide working outputs but only as separate devices. -------------

| So I uninstalled the driver but there is still a Buzzing when the GPU is at full load. So the audio is then not properly shielded I guess |

I installed my XONAR DGX and the Humm/Buzzing is gone. So what to do next? I already contacted the ASRock Customer Support via Facebook they forwarded me to an email address. They told me that the audio on the board is galvanic separated and it only could be a ground fault. I hope I translated it correctly cuz I'm from germany and I contacted them in my native language |

Are you sure your PC is properly grounded? The sound on Taichi is great and better than most ALC1220 based solutions when working properly, no need for external sound card for normal use. X470 Taichi's dynamic range is a bit lower than on X370 Taichi, but it's a very little difference. -------------

I might be wrong about good quality on X470 Taichi, I looked in one review, then another, and they weren't pleased with quality in the latter https://www.techpowerup.com/review/asrock-x470-taichi-ultimate/8.html -------------

My previous board also had a ALC1220 chip on it. It was ok for me I'm no audiophile. My PC is grounded good. Every Mainboard which was in there doesn't had the issue. The Taichi is definitely the fist one. |

| Will wait until the ASRock Support will get in touch with me. If I have a chance to RMA it then I will do it. Just to point out whats the problem. If this doesn't fix it I will go dig deeper |
