Are you currently running Linux on it? If so, what kind and what is your experience so far? I am on a Fairphone 4 myself. Content with CalyxOS, but mobile Linux as daily driver is definitely where I want to go. My impression is that not all features work reliably yet. I would need regular phone functionality (incl 5G), GPS and camera to work at least.

Ok, thanks. I don’t want to name (and shame) them before they’ve had a chance to provide other options, and I’ve been happy with the support from them before. But I know it doesn’t help you help me. I’m pretty sure it is not integrated based on the way they describe it. I could try to open it later and see if I can identify it. A decade of Macbooks, and the prospects of opening a laptop seems scary somehow, even though I’m an engineer and have regularly opened up much more expensive equipment in my work… though not computer related.

From the way they describe it in their answers to me, it seems they believe the fault is in a subboard that can be replaced (although with the possibility of a fault in the mainboard as well). If it’s just connected with a ribbon connector, is that something you generally would be able to replace yourself? I might still end up having to send it in, but the wait time is in this very moment unbearable.

I do have a USB audio interface that I use when “docked” at my desk, and I use a headset when I am on the go (which is seemingly not affected at all by this, I suspect there is a connection to the speakers themselves that is affected). This is mainly a problem when using it somewhere else in my apartment, and especially in the sofa where it is moved a lot while on it.
