Error joining voice channels: "failed to join voice channel: establishing connection failed"

This is almost certainly an issue caused by Discord beginning enforcement of end-to-end encryption via the DAVE protocol:

• https://support.discord.com/hc/en-us/articles/25968222946071-End-to-End-Encryption-for-Audio-and-Video
• https://discord.com/blog/meet-dave-e2ee-for-audio-video

There's a songbird issue and PR:

• E2EE/DAVE protocol required serenity-rs/songbird#293
• DAVE support serenity-rs/songbird#291

I'll try out the branch from beer-psi in a branch, but won't close this issue until songbird officially supports the DAVE protocol.

Use the branch from the following PR in the meantime until there's an official release of songbird:
