AEAD AES-256 GCM is reported as not available on Ryzen 9 CPU

[kcrg]

Hi,

I’m encountering a problem where crypto_aead_aes256gcm_is_available() always returns 0 when using DSharpPlus.Natives.Sodium on a Ryzen 9 5900X machine. This results in the exception message:

The current hardware is not compatible with AEAD AES-256 GCM, a requirement for VoiceNext support.

However, Ryzen 9 CPUs definitely support AES-NI instructions, so hardware incompatibility shouldn’t be the issue.

Steps to Reproduce:

1. Use DSharpPlus.VoiceNext in a .NET project with the DSharpPlus.Natives.Sodium package.
2. Run the Discord bot on a system with a Ryzen 9 CPU (e.g., 5900X).
3. Observe the bot immediately crash on startup with the above exception.

Expected Behavior:

• AES-256 GCM should be detected as supported on Ryzen 9 hardware, allowing VoiceNext to initialize successfully.

Actual Behavior:

• crypto_aead_aes256gcm_is_available() indicates AES is not supported, causing VoiceNext initialization to fail.

Workaround:

• Switching to the official libsodium NuGet package resolves the issue, confirming that the hardware is actually compatible and that the error occurs only when using DSharpPlus.Natives.Sodium.

Possible Cause:

• The libsodium native binary in DSharpPlus.Natives.Sodium may be compiled without AES-GCM support or could be targeting an unexpected architecture.

Environment:

• CPU: AMD Ryzen 9 5900X
• .NET Version: 9
• DSharpPlus: Latest version
• OS: Windows 11 x64 (and possibly others)

Thank you!
