Z370 Extreme4 Audio Crackle / Static

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

Hello, 
I have been experiencing an annoying audio crackle / static sound since I built my new computer.  This sound happens randomly when playing audio via web browser and also for in game audio.  This sound can be reproduced by sliding the volume control on youtube videos back and forth and also every time I shutdown or restart my computer it will make a quick static sound right before it shuts down.  

Things I have tried:  

1. installed / uninstalled manufacturer suggested Realtek audio drivers.  
2. disabled all audio enhancements
3. changed between audio bit rates / hz properties 
4. enabled / disabled application to take exclusive control of audio 
5. updated to latest bios 
6. set Ram speed back to auto 
7. disassembled and reassembled my PC to check motherboard standoffs and screws
8. blew dust out of audio jack
9. plugged headphones into front and rear audio jacks 
10. tested with second pair of headphones

Any suggestions on how to fix this problem would be much appreciated because the static sound is driving me insane.

	>1. installed / uninstalled manufacturer suggested Realtek audio drivers. Did you download the audio driver from Asrock website ? Are you overclocking anything ? Edited by badbri - 28 Mar 2018 at 9:09am

	This is not uncommon on Win 10 and or with Realtek HD audio. It's not likely your motherboard. It happens on Asus and Gigabyte as well and there are threads all around about it. One official response from Asus pr in their forums is that it has to do with how Win 10 handles HD audio, and or along with the Realtek drivers - i'm paraphrasing here. It's not specific to any chipset or codec as posts about the same issue go years and years back. I did have some static on my new build with k6, mostly with windows "sounds". My audio bit rate was defaulted to 24bit 44100Hz, i dropped it to 16bit 192000Hz studio and the crackles went away. Eventually i would rather be able to use 24bit if i so chose though. I record and mix on my pc and it worked fine in Win 7 with z77 and Realtek drivers. That's really just one variable but seems to be common. It could also be a latency issue, and or Nvidia drivers as well, which is also not uncommon. When you install Nvidia drivers i recommend only install the driver and physx. Do not install the hdmi driver if you can help it. And also check your system latency with latency mon. If you do a web search you can find threads about it. Edited by MKVII - 29 Mar 2018 at 12:52pm
