Audio crackling after switching GPU (pipewire / pulseaudio).

Ateku · 2025-12-14 11:42:22

Hello,
I did upgrade my PC from RX 6600 8GB to RX 9060XT 16GB graphic card, and I noticed that when anything graphical happens, like switching tab or launching game, the audio crackes for a split of the second. This did not happen on the previous GPU (I did switch it back to check if that's what was causing it to confirm it). The CPU I'm currently using is R5 5500.
What I tried doing:
- Changing settings with pulseaudio with or without pipewire ex.: changing clock min and max quantum.
- Setting CPU power to governor performance.
- Doing a fresh install of Arch Linux.
- Tried to check if power cable connected to GPU could cause any interference (moving it around).
- Disabling Resizeble-Bar in BIOS.
- Downgrading packages for pipewire.
- Changing the Jack that my headphones are using from front to back of the case.
What I observed:
- This only happens under GPU load. If the HDMI cabel is not connected to the GPU, the issue does not happen.
- Bluetooth works fine.
- The load on GPU is irrevelant. Playing demanding games can or cannot cause it.
- This might had happen on Windows 10, but I'm not 100% sure, because on Arch I can fairly easy see it by changing tabs in Qutebrowser.

For time being, I will use BT solution, but it is not ideal.

- This only happens under GPU load. If the HDMI cabel is not connected to the GPU, the issue does not happen.
- The load on GPU is irrevelant. Playing demanding games can or cannot cause it.

How do we square that?
Also, do you playback audio via HDMI or using some line-out or headphone jack on the board or a usb headset etc et pp?
If there's no HDMI cable attached the the GPU, what kind of output are you using?

with pulseaudio with or without pipewire

Sanity check

systemctl --user status pipewire wireplumber pulseaudio

Ateku · 2025-12-14 21:20:14

The audio is played via headphone jack.
About GPU load, I did some testing around it with playing under high GPU usage vs at low GPU usage, and it does not matter when it will happen. It is mostly noticable when switching tabs in quick succession, but it not even happen for one second, as long as the tab is not switched or anything new is opened, the audio plays fine. I do have Qutebrowser as my default browser which lets me to change tab to last used by holding the keybind by which I hear that it still happens after all fixes and research done online.
What I meant by "with pulseaudio with or without pipewire" is that I tried to use pipewire with pulse - pipewire, pipewire-pulse, wireplumber - or just pulseaudio.

The output of the command:

I did play around it a little bit more, and strangely enough, the problem is solved temporarly if I change the volume of the headphones using ncpamixer (ex.: from 60 to 61 back to 60). After reboot, the problem resets.

seth · 2025-12-14 21:45:58

There's been some other thread about poor sound w/ low volumes, https://bbs.archlinux.org/viewtopic.php?id=310368

=> See https://wiki.archlinux.org/title/PipeWi … 30%_volume
Ignore the context but nb. that "alsa_card.name-of-device" is a placeholder (the other thread should allow you to come up w/ a proper value)

This doesn't explain it being somehow related to the HDMI cable, do you have other means of attaching a monitor?

Ateku · 2025-12-14 21:59:45

I did the conf file, restarted pipewire wireplumber and pipewire-pulse, but did not help.
I tried to change the volume in alsamixer, but it did not help even temporarly, only using ncpamixer.
The volume level does not matter, 60 is just what I'm using, but on 100 it still happens.

I only have HDMI cabel right now. I will order DP cabel, either way, I will have use for it even if it will not help.

seth · 2025-12-14 22:08:06

What are you currently doing when not using the HDMI cable and is the sound reproducibly better then?
If yes using the SW mixer won't systematically help and your previous experience might have been a fluke.
It would then also not be https://wiki.archlinux.org/title/PipeWi … ample_rate

Can you move the headphones or monitor around to spread out the cables?

Ateku · 2025-12-14 22:18:50

If you mean what I did when I removed the HDMI cable was the same test what I'm doing to check if crackling sound happens - switching tabs. The crackling sound does not happen if I remove the HDMI cable.
Just in case this is important. The HDMI input for GPU is directly under the JACK connection for motherboard, BUT the headphones JACK is connected from front.
About context.properties, I did it when I searched for solution online. Nothing helped when changing pipewire or wireplumber config files.

I did moving the cables around. I tried to plug the headphones to motherboard from back of the case, or changing the monitor, or monitor settings.

About ncpamixer, the app needs to run in the background to work, otherwise, it will revert to the previous state if I refresh any of the pages or launch any app like Discord.
If the first thing I start when I boot my system is ncpamixer, the crackling sound stops when playing audio, as long as ncpamixer runs in the background.

Edit:
Added the hack in Hyprland config to launch the ncpamixer at start, and works fine so far:

exec-once=ncpamixer

But how do you see anything? Do you attach the monitor to another GPU or another monitor via VGA etc?

About context.properties, I did it when I searched for solution online.

https://bbs.archlinux.org/viewtopic.php … 9#p2261679
And does "pactl list sinks" currently list "api.alsa.soft-mixer = "true"" for the relevant device?

Just in case this is important. The HDMI input for GPU is directly under the JACK connection for motherboard, BUT the headphones JACK is connected from front.

If it's leaking EM that might interfere w/ the signal enough - was the old GPU/output in the same spot?

Ateku · 2025-12-14 22:53:18

If I unplug the HDMI cable, the GPU is not connected to any external sources. I use the same keybind as when the HDMI cable is plugged, so there is no issue knowing the tabs are switched. The keybind is switching between current one and last used by just holding the keybind, it happens multiple times in a seoncd.

The "pactl list sinks" lists "api.alsa.soft-mixer = "true" for the only output I have (my headphones).

The older GPU did have the HDMI connection further away by far from motherboard. I just thought, it might be relevant.

seth · 2025-12-15 20:07:18

Can you move the GPU to a different PCI slot?
x-ref, https://bbs.archlinux.org/viewtopic.php?id=311020

Edit: the other user gets good audio *via* HDMI?
Can you confirm that?

Ateku · 2025-12-15 21:11:20

I only have one PCI express slot for GPU as it is micro ATX motherboard, so cannot change the GPU slot.

Not sure what it means by other users, but if you mean other accounts on the PC, then the answer would be that it is the same, because I did format my Arch install, and I have experienced the issue before format.

seth · 2025-12-15 21:13:24

Not sure what it means by other users

See the link in #11

Ateku · 2025-12-15 21:24:51

If I connect the headphones directly to my monitor (expect for some white noise, because it's not the best monitor), the audio works fine as the other user said.

Different boards.

If you only boot the multi-user.target (2nd link below) and from the console play "mpv thunderstruck.mp3", do you get any artifacts (crackling)?

Ateku · 2025-12-15 22:43:16

I tried the commands from the 2nd link, but the GUI still launches, even when isolating graphical.target, when I login by exec Hyprland script. From `systemctl get-default` I got that it changed to multi-user.target.

The mpv output runs fine, without any issue.
I ran "sudo journalctl -b | grep -i DMI" again after reboot the system and the output looks the same as Ateku:

That message probably appeared earlier today when I was changing some settings to try and fix the audio.

seth · 2025-12-15 23:03:44

The mpv output runs fine, without any issue.

But not on hyprland?
startx some xterms and try there…

@Ateku, isolating the graphical.target means to start it.
Add "systemd.unit=multi-user.target" to the kernel parameters and reboot or "systemctl isolate multi-user.target" !!!which will probably kill your hyprland session!!!
