You guys need to try out streaming from PC and/or PS5 to Steam Deck. Technically everything runs on the SD in this scenario. I’m playing FF7 Rebirth on the SD via my PS5 right now, and it is glorious. Helldivers 2 via the gaming rig is also pretty sweet.
Steam’s built in Remote Play and Chiaki4Deck are the best!
I have this issue as well :( I have PTT in Helldivers 2 bound to one of the back buttons, when I hit it the >)) mic icon lights up on the HUD, but no one can ever hear me. Hopefully the community can provide a fix, or some more clarification from Valve would be nice also
