Valve released SteamOS version 3.8.5 Beta on May 21, 2026. This update addresses specific hardware issues across supported gaming handhelds. The patch targets the Steam Deck OLED and ASUS ROG Ally platforms.
Latest patch resolves speaker loss issue on Steam Deck OLED and improves ROG Ally support for users enrolled in the beta channel.
The primary fix resolves an audio bug on the Steam Deck OLED. Rebooting the device occasionally caused a complete loss of speaker output until performing another reboot cycle. Valve also improved video memory management for discrete GPU platforms in this release.
Users must enroll their devices in the Beta channel to receive these changes. The update is available globally for compatible hardware. Valve has not announced specific pricing or availability windows beyond the beta distribution method.
The patch includes fixes for Desktop Mode application retention issues. A regression from previous 3.8 builds caused control misbehavior on the ASUS ROG Ally after resuming from suspend mode. These changes aim to stabilize core functionality across supported handhelds.
