I’m not sure if both have a separate audio board. I’ll try with my Senfer DT6 as well, those are great and relatively cheap. I also have some other in-ears and headphones, to confirm that the impedance is the important factor.

I’ve tested a few pairs of earphones and a pair of headphones (Very noisy: Sennheiser IE80, no noise: Philips Fidelio X2HR, Phonak Audeo PFE 112) and it looks like ones with 16 Ohms impedance exhibit a lot of noise, while 30 Ohms and up ones are silent.

I expect all of them to have the awful static on the headphone output. I sounds exactly like there’s a common ground between the system and audio hardware. I have this exact same problem with other hardware, it is a design fault.

For storage devices to work properly you need to change a setting in the BIOS. I don’t remember which setting exactly, but if you do a search in this subreddit it will probably turn up.

I don’t expect you could swap out the boards, a lot of the components have changed.

I’m quite sure this isn’t a software problem. My official Sony PSOne display and MiSTer FPGA have the same noise and it is caused by the grounding problem I mentioned.

Should it be the headphone wires inside picking up the noise, a shielded cable might fix it. But I don’t expect that to be the cause of the problem.

I just checked and I have the same thing on my 512GB OLED. This is a hardware bug. Sounds like system and audio grounding haven’t been properly separated.

It sounds quite bad, makes me wonder how this made it past QC.

One, not really acceptable solution, is to use a USB-C to headphone adapter. I just tried the cheap Apple one and it works perfectly. My Zorloo Ztella also works. My passive OnePlus cable doesn’t work, unsurprisingly.

Downside of that workaround is that the adapter will consume a little bit extra power.

Grip, haven’t gotten it to work yet myself, look here: https://steamcommunity.com/app/396900/discussions/0/1652169858536175563/#c1644295067080498033

These are Unreal Engine settings, so it might work for other Unreal-based games, or you could borrow well working settings from other Unreal games.

Mentioned settings might not be perfect for the Deck, I don’t know if the exact HDR standards the Deck is using can be found anywhere yet.
