Question Audio and video stuttering on new build, but not when gaming ?

[DIegoKermit]

Hello! I've been dealing the last couple of days with huge stuttering in audio and video. I just built my pc, and everything was just perfect for about two weeks, and one day suddenly the stuttering began out of nowhere. It does this primaraly in destop, when doing work stuff or whenever there's low usage or stress, I can't play music, videos or streams without stutter, but whenever I play heavy duty games (i.e. Baldur's Gate 3 at ultra) everything works just fine and smooth (low duty games like LoL show stuttering). Sometimes randomly it just fixes and for a couple of minutes everything runs smoothly, but it always come back to stutter

Whenever I turn on my PC everything runs smoothly, but as soon as I start any programa, the stuttering begins. I've even removed the GPU, using the Mobo HDMI port and the stuttering in desktop is still there.

Solutions I've tried (almost everything I've found while searchind the Internet) :
-Fresh W11 instal
-MoBo BIOS update
-Disabling UPLS vía Afterburner
-setting gpu min clock speed 100 mhz lower than máx speed
-downgrading my gpu driver by 2 versions
-clearing CMOS
-physically checked that components were correclty plugged in, and the cpu pins weren't bent.
-ran cpu and gpu benches. Cinebench ran smoothly,


My setup:
CPU: AMD Ryzen 5 7600
OS: Windows 11 (64 bits)
GPU: Sapphire Pulse AMD Radeon RX 6700 XT
PSU: Cooler Master MWE 750 BRONZE V2 80 PLUS
RAM: Corsair Vengeance DDR5, 5200MHz, 32GB (2X16)
MB: MAG B650 TOMAHAWK WIFI

How is audio set up - are you using HDMI or DP for audio, and if so is there a way for you to switch to something else, even some cheap headphones run off the motherboard temporarily? I had all kinds of issues with sound stuttering and cut-out using AMD's audio driver and HDMI out that went away entirely when I switched to another sound device and disabled the AMD sound driver.

Grab LatencyMon and let that run in the background for a while, several hours ideally, though if you're getting big spikes quickly it may not take that long. Then disable the AMD sound driver and see if that helps. If it does, maybe time to get a cheap USB DAC or something.

update the bios of the motherboard to the latest version
7D75v1A
update amd chipset drivers

already did, still stuttering after updating both

I'm using dual monitor, one with DP, one with HDMi. Both audios stutter (I usually plug my headphones to de DP screen). When I plug my headphones to the front plug of my case, audio stutter almost enterely goes away, while video stutter is minimal
.

Running latencymon.

boot with ubuntu live and try video/audio playback

I bet if you get a cheap USB DAC and disable your existing sound devices this will go away. Very good chance it's a misbehaving sound driver. If it's Realtek try rolling back a version or two. Don't use AMD's GPU sound driver, it's dreadful. I got rid of literally all the issues I was having with audio and video playback since switching to a 7900 XTX by using an external DAC.

Did it, and everything worked just fine, no stutters

how did you install windows ?

try ddu uninstaller and reinstall nvidia drivers from nvidia.com
