§1 Fixing Disappearing Sound:

If your sound, goes silent after a certain time or early in the game - Make sure you have the following sound settings (without applying any filter/sound enhancements to "make it sound better"):

Stereo - 16bit - 44100 Hz

The following software are known to cause conflicts with Supreme Commander or the FAF client:

Steel Series GG Software Suite
Steel Series and Corsair Driver Packages
Creative Speaker Drivers
Killer Audio/Networking
Citrix Systems
Overwolf Overlay
Sophos VPN
Asus GPU Tweak III

The following hardware may cause conflicts:

Intel Core stability issues in 13th and 14th Gen Processors (Discord Thread About The Issue: Link)

It's important to note that Forged Alliance was developed before 5.1 or 7.1 surround sound technologies became available, and as such, they are not compatible.

Example to change it:

§2 Fixing Crashes Related to Sound - SND: Error, XACT: Invalid arg, XACT3DApply failed

Verify sound as the root cause, test the game without sound (shouldn't cause crashes), and inspect for UI or SIM mod issues.

How to disable the sound properly:

FAF Launcher ⇾ Options ⇾ Forged Alliance Forever ⇾ Command Line Format for Executable ⇒ add /nosound behind the "%s"

2.1 Uninstall FAF and Supreme Commander completely and remove any leftover files, so we can begin with a 100% working environment.

Make sure no leftover files are in: (Path may be different, if you have the GOG version, or you have selected a different installation path.)

C:\Program Files (x86)\Steam\steamapps\common\Supreme Commander Forged Alliance

C:\Users\%username%\Documents\My Games\Gas Powered Games\Supreme Commander Forged Alliance

C:\ProgramData\FAForever

%LOCALAPPDATA%\Gas Powered Games\Supreme Commander Forged Alliance\

2.2 Install the latest client release from FAF:

https://github.com/FAForever/downlords-faf-client/releases (Or go to https://www.faforever.com/play)

Install Supreme Commander via Steam or GOG

Test for sound issues with a new installation. If problems persist:

Ensure Windows is updated.
Configure sound card to stereo mode.
Set sound card to 44100 Hz / 16 bit; consider 44100 Hz / 24 bit
Disable sound enhancements for your sound card.
Deactivate unrelated sound devices (restart PC).

If you have a USB sound card like Focusrite and other devices, disable everything except your primary sound card (e.g., NVIDIA and Waves SoundGrid). If you're not using your onboard sound card, consult Google or your motherboard manual to deactivate it through the BIOS.

Example: In this image, NVIDIA and Waves SoundGrid were deactivated:

- 3.1 Uninstall Sound Software & Try Alternate Speakers for Testing

Consider using other audio devices, such different pairs of headphones/speakers or audio hardware. Uninstall any additional software that applies filters or effects to your sound and stick to using basic drivers to avoid potential problems. Avoid high frequencies and bit depths (Example: 96000+ Hz / 32 bit).

- 3.2 Delete Sound Files Responsible for Crash

Head into your steam folder for SupCom:FA and delete both music files (The .xwb and the .xsb)

C:\Program Files (x86)\Steam\steamapps\common\Supreme Commander Forged Alliance\sounds

- 3.3 Reinstall Everything

Reinstall Windows, do not install any third-party software and try only with FAF and Supreme Commander.

- 3.4 NVIDIA Broadcast/Virtual Audio Cable

Conclusion:

The cause of the disappearing sound error is unknown (Well, it is a ~20-year-old game engine) and there is no guaranteed solution, even after many years. It may be related to numerous factors, which makes it difficult to determine the root cause, but it is related to the sound card or other software/hardware that affects sound in some way.
