Today I docked my Steam Deck for the first time, tried it for 30 mins and it worked well. I go to undock it and turn it on, as soon as I do it blasts this extremely loud sound that scared the living hell out of me and my girlfriend, it was so loud I didn’t even know the Steam Deck could do that.

It was like a siren or something. After that I restarted it and everything looked fine, except the audio crackled a couple of times when I used the home screen.

I have not seen this reported much and it seems like a more recent issue? Because the other posts I see about this don’t go further than 50 days ago.
