SteamOS 3.7.15 Beta has just been released. The latest version of the Steam Deck’s operating system is now available for Steam Deck Beta and Preview channel users. To access this on a Deck, tap the Steam button on your handheld, navigate to Settings > System > Software Update, then change your channel.

The new beta comes with a pretty solid amount of fixes, many focused on sleep/wake improvements and fixes to audio settings. There’s also multi-language support for the screen reader accessibility feature. On top of all that, non-Deck handhelds (the ASUS ROG Ally and Lenovo Legion Go) also get some notable improvements.

SteamOS 3.7.15 Beta patch notes

Prior to this update, the ASUS ROG Ally had an annoying sleep/wake-up issue on SteamOS. If you left the device to go to sleep (or put it in sleep mode), and then later woke it up, the back grip buttons simply wouldn’t work. The Legion Go gets improvements to controller firmware and FPS mode (when the controllers are detached); this update comes just as Lenovo Legion Go 2 pre-orders went live.

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

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

Although SteamOS only currently comes installed by default on the Steam Deck and Lenovo Legion Go S, it is possible to install the Linux-based operating system on other third-party handhelds. Valve put out a guide for this, and support is slowly but surely being improved for these alternative AMD-powered handhelds, which generally ship with Windows 11 installed.
