Fix Slay the Spire 2 No Sound Issues

You launch Slay the Spire 2 expecting music and effects, but you are met with total silence. It is incredibly frustrating when you just want to play, and this usually happens because the game is defaulting to the wrong audio output or your hardware settings are out of sync with the game engine.

Why this happens

Most audio issues in this game are caused by the game failing to handshake with your active audio output or a conflict with high-frequency audio sample rates.

Steps

1. 01
   Open the in-game settings menu and navigate to the sound tab to ensure that the master volume and individual sliders are not muted or set to zero.
2. 02
   Click the speaker icon in your Windows taskbar and open the Volume Mixer. Ensure the output device is correctly set to your active speakers or headset, as the game may be routing audio to a disconnected monitor or secondary device.
3. 03
   Right-click the speaker icon in the taskbar, select Sound settings, and click More sound settings. Right-click your active output device, go to Properties, open the Advanced tab, and set the Default Format to 24-bit, 48000 Hz to resolve compatibility issues.
4. 04
   If the game is still silent, open Steam, right-click Slay the Spire 2 in your library, and go to Properties. Select Installed Files and click Verify integrity of game files to repair any corrupted audio assets.
5. 05
   If you are currently using a Bluetooth headset, disconnect it and switch to a wired connection. Bluetooth devices often experience driver-level audio drops with this game engine.

Still not working?

If you have verified the files and checked your output settings but still hear nothing, check your Windows Device Manager to ensure your audio drivers are up to date. If other games produce sound but this one does not, try disabling any third-party audio enhancement software or spatial audio wrappers, as these can conflict with the game's audio driver calls.

Frequently asked questions

Will verifying game files delete my save progress?

No, verifying your game files only replaces missing or corrupted installation files and will not affect your save data or progress.

Why does Bluetooth audio have so many issues with this game?

Bluetooth audio uses a different connection protocol that can time out or enter a power-save mode, which often causes the game engine to lose the connection to your headset.
