Hello everyone,
I’ve bought a new (second-hand) PC and simply installed the hard drives from my old laptop into the new machine. Everything works perfectly (go Linux 
), except for the speakers.
Old system: HP Probook, new system: HP 27 aio.
The Bang & Olufsen speakers produce a crackling sound. To check if they’re faulty, I tested them with the original Windows 11 – they work, and playing music without crackling was no problem.
The headphone jack works as well. I can plug in headphones and get sound - no crackling.
I’ve already searched the internet for the sound card and drivers, but none of the solutions worked, the crackling don’t go away.
The sound card is an Intel Cannon Lake PCH cAVS, as recognised by the kernel. Under Windows 11, it was displayed as Realtek VLC255.
Soundserver is pipewire.
Kernel 6.18.18-1
Here are the outputs from the various programmes:

Does anyone have any advice for me on where or what else I can look for to track down the fault?
Thanks …

I had it work once, but I didn’t understand why. Because I’d been in suspend mode beforehand. Who would think of that 
?
