Question Crackling audio under heavy load?

[begix_]

Hi everyone,first of all i don't know if I'm in right section so sorry about that.
My issue is really weird,I'm having random crackling audio or even small pops when I'm playing game with higher graphic for example:Fnaf Security Breach on Ultra.My setup can handle it easilly because I played that game one year ago and there was no problem with audio.However back then i had old headphones just regular ones with minijack port.Month ago i bought Beyerdynamics dt 770 pro 80 ohm and thinks started going crazy.I updated all my drivers,literally evberything,updated Bios,Change powerplans,send back headphones and got new one,change PSU,Change RAM to higher Hz,Checked my ssD,change my MOBO to same model and problem still occured,my focusrite audio device got changed too and nothing helped. I saw a lot really a lot of posts about crackling audio with my CPU amd Ryzen 5 5500 and maybe this PCU is not strong enought to handle better games with those headphones? If someone got any idea what could be wrong with my setup let me know.

My setup:
CPU:Ryzen 5 5500
GPU:RTX 3060Ti 8GB
RAM: DDR4 32GB 3733MHz
MOBO:MSI MAG B550 Tomahawk
PSU:Be quiet 750W
CPU Cooling:Spartan 4
OS:Windows 11

Considering what you've tried already it looks like a specific CPU - Memory issue (your PSU is fine):

As one of the people here say, can you try playing a game with 1 stick of ram only? If that doesn't work try disabling XMP/DOCP in the BIOS to see if the issue goes away when the RAM is not clocked as high

BTW Have you tried another pair of headphones?

Thanks for the reply, i forgot to mension that i also experiment with xmp profiles and it didn't helped same with changing PCiE settings in Bios.I checked the post and well playing with 1 stick of ram and on 2400hZ insted of 3733 will kinda hurt but I will check if this help.

Well i got a new one from store same pair of beyedynamics dt 770 80 ohm because my first thought was that they are broken and that's why they game me secound pair.

I tried doing 3733hz speed on 1 stick didn't work but doing auto speed in that case 2400mhz(auto) on 1 stick worked somehow? I turned on game and it didn't even cracked a bit.But that's really odd my sticks are supported on MSI just checked that and it says 3733mhz speed.Gonna try second speed on 2400mhz and slowly boosting hz up for more till it become unstable i quess.It's really crazy for me.Maybe i should change voltage to higher amount in BIOS?

Okay so apparently when i put second stick the crakling just came back! Holy cow what is going on with this RAM.

What's your DPC latency? Get latencymon and report back with your findings.

On what setup do u want me to use latencymon?
1 stick or 2 and on what mhz?

Both.

Have you been messing around with your audio sample rates by chance?

Both.

No not really when i bought focusrite device It was automatically set on 48000 and buffer size 512.
I remember that i used latency on 2 stick 3733mhz back when i wanted to replace my focusrite audio.It did not show anything, literally everything on green but i will give screns shots when i'm done.

Your memory clock rates won't affect anything because capacity is more important, but it doesn't sound like a hardware issue. It appears to be a software conflict. The trouble with high DPC latency is that it's often hard to pinpoint the root cause because there are so many variables involved. What works for others might not work for you.

A clean install may be the easiest and quickest remedy. Ryzen systems are finicky when it comes to Windows updates. As for your sample rates, those are always best left untouched.

Did latency tests all green giving you screenshots,

At the very least, this is encouraging. What happens when you play audio files or something more demanding, like 4k videos? Any deviation? If not, and you haven't considered a dedicated desktop amp/dac yet, now would probably be a good time. I'm sorry. It's probably not the response you were anticipating.



Having a dedicated amp+dac should resolve the problem. Focusright products try to do too many things at once, and sometimes having a more streamlined solution is best. Make sure your USB cable is connected directly to the CPU and not the chipset. With newer boards, these are typically colored red (10G) for the chipset, and blue (5G) for the CPU. Check your motherboard's manual just to be sure.

In the link I sent in the first reply the guy explains that it has to do with FCLK in the bios.

Then people wonder why Intel has such rabid loyalists. It just works...
