Hi Aravisian, it happens regardless of the extension
What is your terminal output for
sudo lshw -C sound
There you go!

For this we have:
I believe that this is your monitor:
This is your integrated motherboard sound:
What is this mystery item? Looks like it may be an Amplifier?
You have two generic drivers - I do not see anything that is vying for control over sound:
Things you can try:
When the sound cuts out, load alsamixer:
alsamixer
tap F6 and look through the hardware output for MM (Muted) on any channels that are for speaker output. See if something is Automuted.
Use pavucontrol
sudo apt install pavucontrol
Launch:
pavucontrol
Go to the Output tab and check the drop down menu for what is set as output.
See if that changes after the sound cuts out.
The mystery item is an audio interface.
Alright, I will try when this happens again, thank you!
This might be due to the sound service suspend-on-idle.
More info:
If you still have issues with audio cutting out, you can try editing /etc/pulse/default.pa.
Change:
### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle
To:
### Automatically suspend sinks/sources that become idle for too long
# load-module module-suspend-on-idle
And edit /etc/pulse/system.pa.
Change:
### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle
To:
### Automatically suspend sinks/sources that become idle for too long
# load-module module-suspend-on-idle
Then issue:
pactl unload-module module-suspend-on-idle

Another thing is now happening: the sound is really noisy, it seems like there are interferences, and if I change the audio level it actually applies with some delay... this is really strange
Ps: removing and replugging the displayport cable solves the issue...
Edit: it didnt solve, I had to reboot
2nd edit: it is only happening with the speakers. Restarting pulseaudio solves the issue only 10% of times. Maybe there are problems with the cable? But I doubt this, it was working with Windows...
Hi,
I've tried to apply your solution but I'm still facing the issue reported above.. This is becoming quite annoying
Hi everyone,
does someone know what I can do for this issue?

Did you have any results from this?
Also, check if you have both PulseAudio and Pipewire both installed.
Terminal output:
pactl info
Are you saying it solves the interference noises only, or audio stopping as well?
Instead of displayport cable do you have option to use a hdmi cable to the monitor to test if that helps? (but be aware there are different and directional hdmi cables that can exhibit their own issues).
Hi Aravisian,
after applying what Mr_Magoo said I didn't face any audio cut (I hope it was related and it's not just me being lucky).

Hi! As mentioned above I'm not facing audio cuts for the moment.
Unfortunately I'm not able to switch to HDMI cause of the actual setup (I do have a laptop which is using the HDMI port and it doesn't have the display port plug, so I cannot switch)
Can you please try disconnecting your Webcam (USB) or Microphone (USB) and reboot.
Then test audio.
I'd like to see if the capture device is snagging audio. Some users have had that trouble and needed to set their capture profile to "off' to resolve.
Sound issues are always a headache... I can imagine that this one wants to make you put your head through a wall.
If he does that he will get interference noise from the neighbo(u)rs!

Sorry, I didn't get your point! Should I remove mic/webcam and see if the interference noise happens again?
If this is the case, why isn't this happening when I use the headset, but only when I'm using the speakers?
This is driving me crazy...
You said that your audio cuts out and stops working.
I suggested disconnecting USB devices to see it they capturing audio causing the sound to stop working to speakers.
In terms of 'scratchiness', I have had a similar issue on Antix. The solution? Firstly, I don't use Pulse Audio, just ALSA (Advanced Linux Sound Architecture) and use the application QAS Mixer:
The solution? I turned down Pre-Amp as much as possible - problem solved.
However in terms of sound cutting out it can be because there is more than one device available.
See my advice on creating a blacklist.conf to disable audio sources not needed:
Hi all,
sorry for late reply, been busy with work.
Anyway I'm just facing another audio cut, as an answer to @Aravisian :
Then with alsamixer:

And pavucontrol:
It seems like everything is normal...
EDIT: I figured out there is no need to reboot, terminating the session also works... yet it is a bit annoying
Since you are routing sound through Nvidia:
Which Nvidia drivers are you using? You can check in Software & Updates > Additional Drivers tab.
