Unfortunately OpenTK (The library ocicat uses) does not provide any native binaries for OpenAL. Most Linux distros and MacOS provide OpenAL binaries out of the box, but for Windows you will need to get them manually.
Important
The official OpenAL redistributable WILL NOT WORK! (probably) Your best option is to use OpenAL-Soft.
OpenAL-Soft is available for download here. Download the Win64 and Win32 binaries.
Copy the files:
- router/(Platform)/OpenAL32.dll
- bin/(Platform)/soft-oal.dll
into (Your Project Path)/bin/(Your build mode)/net8.0/runtimes/(Platform)/
Platforms:
- win-x64/Win64 - 64-bit Windows
- win-x86/Win32 - 32-bit Windows
