My LED Steam Deck recently started to increase volume on its own. Even when I turn it down, it goes back up to max right away. Rebooting the system seems to fix the issue for a while, but sooner or later the volume starts increasing again. One time, while rebooting the system, the Steam Deck entered the BIOS, which makes me suspect that the issue might be hardware (audio board) rather than software. Can anyone provide any guidance on this issue?
Also, if the issue is the audio board, does anyone know if iFixit is planning to start selling the audio board for LED Steam Decks (F7A) again? At the moment, the only available Steam Deck audio board is the F7B which is not compatible with LED Steam Decks.
Thank you!
