Description

Summary

When attempting to connect to a voice channel using voiceChannel.ConnectAsync(), the application throws a System.InvalidOperationException with the message "Discord does not support xsalsa20_poly1305".

Steps to Reproduce

1. Create a Discord bot using Discord.NET
2. Attempt to connect to a voice channel using:
   var audioClient = await voiceChannel.ConnectAsync();
3. The exception is thrown during the connection attempt

Expected Behavior

The voice connection should establish successfully using a supported encryption method.

Actual Behavior

The application throws System.InvalidOperationException: Discord does not support xsalsa20_poly1305 and fails to connect to the voice channel.

Additional Information

1. This error occurs specifically during voice channel connection
2. The error suggests that Discord.NET is attempting to use an unsupported encryption method
3. The issue may be related to libsodium dependencies or Discord's supported encryption methods

Possible Solutions to Investigate

1. Automatic fallback to supported encryption methods
2. Better error messaging indicating which encryption methods are currently supported
3. Documentation updates regarding supported encryption methods
4. Dependency checks for libsodium compatibility
