Wired headphones produce a small and continuous hiss while the Deck is powered on. Hiss is very soft in volume, and increases in volume whenever any action is done (whether scrolling or highlighting a button, even if action doesn’t produce a UI sound).
My headphones: sony wh-1000xm5
How to reproduce:
- Plug-in headphone and cable. Leave headphones powered off.
Where/when this issue DOESN’T occur:
- When headphones are plugged into my Steam Deck LED model in the same manner
- When headphones are used with bluetooth
- When headphones are powered on (regardless whether Active Noise Cancellation is on or off)
In desktop mode, changing audio profile from “SOF Vangogh” to “Off” eliminates the hiss. Hiss remains missing when profile change is reverted, though only up until a UI sound activated the Audio Coprocessor. Of course, this isn’t a true solution.

I should also mention that the hiss appears to correlate with UI movement. Note the following:
- Hiss is constant
- Hiss increases in volume when cursor floats above element.
- Hiss increases in volume when pop-up element appears
- Hiss returns to base volume when cursor doesn’t move
- Hiss, again, increases in volume when pop-up element expires and fades out
- Hiss, again, returns to base volume after fade-out animation ends
Please let me know if anyone of you have this issue as well.
that’s bad then, there’s a ton of ppl reporting this issue.
