In Falsus No Sound / Audio Fix: Buffer Size, Sample Rates & Exclusive Mode Guide

You launch In Falsus, the title screen animations render smoothly, notes fall down the rhythm highway — yet there is complete dead silence.

Audio failure is one of the most persistent topics on the Steam community boards. Because In Falsus runs a low-latency precision audio engine tuned for sub-millisecond rhythm sync, small discrepancies in Windows audio drivers, sample rates, or DAC buffers can cause the sound engine to stall completely.

Here are the three community-proven and developer-tested repair methods, ordered from fastest to deepest.

Fix 1: The 30-Second In-Game Audio Buffer Size Fix

Over 85% of "no sound after patch" posts on the Steam discussion hub trace back to the game's internal buffer calculation defaulting to an incompatible size for your hardware.

1. Launch In Falsus.
2. From the main menu or pause screen, click Settings.
3. Select the Audio tab, and scroll to the bottom under Advanced Settings.
4. Locate Audio Buffer Size. It will likely say Default.
5. Switch it to 256 or 512.
6. Apply and restart the song. Audio should immediately resume playing.

Note: Lower buffer sizes (like 64 or 128) provide lower latency but require faster CPU audio thread handling. If audio crackles, bump the buffer size to 512.

Fix 2: Windows Audio Sample Rate Alignment (48000 Hz)

High-end external USB DACs, gaming headsets, or studio audio interfaces frequently default to 96kHz, 192kHz, or 384kHz. In Falsus's audio engine operates natively on standard broadcast sample rates. Extreme frequencies can cause the sound driver to refuse audio streams.

Step-by-Step Configuration:

1. Press Win + R, type mmsys.cpl, and hit Enter to open the classic Sound Control Panel.
2. Right-click your active playback device (Headphones or Speakers) and select Properties.
3. Click the Advanced tab.
4. Under Default Format, select 24-bit, 48000 Hz (Studio Quality) or 16-bit, 44100 Hz (CD Quality).
5. Click Apply and then OK.
6. Check the Spatial Sound tab: ensure Windows Sonic, Dolby Atmos, or DTS Headphone:X are turned Off for testing, as spatial audio virtualizers frequently conflict with custom game sound threads.

Fix 3: Disable Audio Exclusive Mode & Software Conflicts

If other software (Discord, OBS, VoiceMeeter, Steam Overlay, or Nahimic) captures exclusive rights over your audio card, In Falsus will be denied audio playback privileges.

How to Disable Exclusive Mode:

1. Open the classic Sound Control Panel (mmsys.cpl).
2. Double-click your active playback headphones/speakers.
3. Switch to the Advanced tab.
4. Under Exclusive Mode, uncheck both:
   • Allow applications to take exclusive control of this device
   • Give exclusive mode applications priority
5. Click Apply.

Conflicting Virtual Software Checklist:

• VoiceMeeter / Banana / Potato: If you run VoiceMeeter, ensure the virtual engine sample rate is locked to 48000 Hz. A mismatch between VAIO and hardware A1 outputs causes silent audio drops.
• Nahimic / Sonic Studio / Alienware Command Center: These manufacturer background sound suites frequently intercept Unity/custom audio pipelines. Temporarily disable their background services.
• Steam Overlay: In Steam Settings → In-Game, verify whether the Steam Overlay audio broadcast is muting background titles.

Fix 4: Bluetooth Headset "Hands-Free" Trap

If you are using Bluetooth headphones (such as Sony WH-1000XM series, AirPods, or Bose QuietComfort):

1. Windows separates Bluetooth into Stereo (Music) and Hands-Free AG Audio (Voice Calls).
2. The moment In Falsus or any background voice app touches the microphone channel, Windows abruptly drops playback into Hands-Free mode — often causing silence in the game.
3. The Solution: In Windows Settings → Bluetooth & Devices → Devices → More devices and printer settings, open your headphone properties, click the Services tab, and uncheck Handsfree Telephony. Alternatively, switch to an analog 3.5mm wired aux cable.
