SteamOS 3.7.15 brings fixes for ROG Ally, Legion Go, wake-on-bluetooth returns for Steam Deck LCD and more

Valve released SteamOS 3.7.15 stable bringing improvements for the Steam Deck, Asus ROG Ally, Lenovo Legion Go and lots of security issues fixed. Overall it seems like Valve solved a real number of really annoying issues with this release.

The Steam Deck and Lenovo Legion Go S are still the only officially supported devices, but you can still try it on basically anything. Bazzite is still likely your better Linux option for other handhelds though.

Here's all that's changed:

General

• Fixed power and clock limits sometimes getting reset after sleep
• Fixed a case where WiFi would fail to connect after sleep
• Improved battery charge time estimation

Bluetooth

• Re-enabled experimental wake-on-bluetooth support for Steam Deck LCD, including support for LE peripherals

Accessibility

• Enabled multi-language support for the screen reader. The screen reader will default to the language configured under Settings->General.
  • The screen reader language may also be manually configured under Settings->Accessibility

Audio

• Fixed volume jumping to 100% upon removing 3.5mm headphones
• Fixed USB audio devices not being automatically switched to when connected
• Removed non-functional "Pro Audio" profile setting in desktop mode, which would disable audio until deselected
• Fixed audio glitches in Ori and the Will of the Wisps
• Fixed audio distortion with the Steam Deck microphone in game recordings

Non-Deck

• Fixed grip buttons after sleep on the original Asus ROG Ally
• Improved support for the Lenovo Legion Go when using controllers detached in FPS mode
• Added support for updated Legion Go Controller Firmware

Misc

• Fixes for security advisories CVE-2025-55188, CVE-2025-6021, CVE-2025-6170, CVE-2025-49794, CVE-2025-49795, CVE-2025-49796, CVE-2025-6395, CVE-2025-32989, CVE-2025-32988, CVE-2025-32990, CVE-2024-23337, CVE-2024-53427, CVE-2025-48060, CVE-2025-49014, CVE-2025-8067, CVE-2025-8067, CVE-2025-7425, and GHSA-f946-j5j2-4w5m
