In Falsus No Sound / Audio Not Working: Fixed

A rhythm game with no sound is unplayable, and the "no audio" problem is one of the recurring complaints in the In Falsus Steam community. The good news: one fix has been confirmed by players to resolve it for a whole class of audio setups, and it takes about thirty seconds.

The community-confirmed fix: increase the audio buffer size

At least one Steam discussion thread reports the fix directly: increase the audio buffer size in the game's audio settings. Look for a buffer-size or latency option in the game's settings (check the Audio section), raise it one or two steps, and restart the track.

Why this works: some DACs and audio interfaces — especially external USB DACs and higher-end motherboard audio — need a larger buffer to keep a continuous stream. With the buffer set too small, you get silence, crackling, stuttering, or audio that cuts in and out. A larger buffer adds a few milliseconds of latency, which brings us to the rhythm-game trade-off.

For a rhythm game, keep the buffer as small as your hardware allows. Increase it only until the audio is clean and continuous — going much higher can make chart timing feel off. In Falsus lets you calibrate timing, so if you do need a bigger buffer, re-run the offset calibration afterwards; our rhythm guide covers how judgement timing works.

Check for a sample-rate mismatch

If the buffer fix does not help, check what sample rate Windows is feeding your output device. A mismatch between the game's output and the device rate can produce silence or distortion:

1. Right-click the speaker icon in the system tray → Sound settings (or Sounds → Playback in the classic panel).
2. Open your active output device's Properties.
3. Under the format settings, try a different sample rate — 48000 Hz (24-bit or 16-bit) is the most broadly compatible choice.

Also confirm the game is actually sending audio to the device you are listening on: check the per-app volume mixer and make sure In Falsus is neither muted nor routed to a different output.

Disable Windows "exclusive mode"

Windows lets applications take exclusive control of an audio device, and conflicts over exclusive mode are a known cause of one app going silent. In the same device properties window, look for the advanced settings and uncheck both "Allow applications to take exclusive control" boxes, then apply and relaunch the game. Players report this resolving silent-game issues across many titles, not just this one.

A word about Bluetooth

If you are playing over Bluetooth headphones or earbuds, be aware of two things:

• Stability: Bluetooth audio stacks are more prone to dropouts and to "connected but silent" states. If the game is silent only on Bluetooth, test once with wired output to isolate the problem.
• Latency: standard Bluetooth codecs (SBC, AAC) add 100–300 ms of delay. Even when audio works perfectly, that lag makes precise rhythm hits nearly impossible and can fool you into thinking your calibration is broken. For serious play, use wired or low-latency (aptX Low Latency / LE Audio) output — this is standard advice across the rhythm-game community, and it applies doubly to In Falsus's judgement windows.

Quick checklist

• Raise the in-game audio buffer size — the community-confirmed fix.
• Set your output device to 48000 Hz.
• Disable Windows exclusive mode for the device.
• Check the per-app volume mixer and output routing.
• Test wired audio to rule out Bluetooth.

Still stuck?

If you have worked through the list and still hear nothing, post in the In Falsus Steam community discussions with your audio hardware (DAC/headset model, wired or Bluetooth) and which steps you tried — the existing audio threads are where players have been trading fixes, and your case helps confirm which solutions hold up. Once your sound is back, see our demo guide for what to play first.
