Another round of Steam Client Beta updates are here with Steam Deck and Desktop PC seeing lots of improvements and bug fixes, and it's especially nice for people using Bluetooth on Steam Deck.
Steam Deck Specific changes:
Show battery information for connected Bluetooth devices under Settings->Bluetooth and in the Quick Access menu.
Added a per-device toggle to Settings->Bluetooth that controls whether a device is allowed to wake Steam Deck from sleep.
Fixed a bug that would cause the UI to show stale data for Bluetooth devices.
Kinda sucks with multi-homed devices like my pixel bud pros because it constantly wakes up the deck until i disconnect them, so this is nice fix being able to toggle devices.
I use my deck every day whether I'm just half playing an idler or plating something more engaging but my power button is struggling. I've done a bunch of the "fix it at home" things so I just hope it doesn't become completely unusable... I could send it back for repair but then I'd be without my deck for weeks...
Maybe try this, in desktop mode make sure the SBC-XQ codec is selected for your headphones, it's night and day difference for me (or can try LDAC if XQ isn't available)
