DAVE support?

[aymendirar]

Summary

It seems like discord's changed their API and are enforcing DAVE encryption on voice channels. The library currently can't connect/send any audio to voice channels and I see these errors when trying to use the voice API:

[ERROR : vws-i @ 2026-04-15 03:27:38.181] VWS error: E2EE/DAVE protocol required

I can repro the same error running this script:

  # Usage: DISCORD_TOKEN=... CHANNEL_ID=... ruby repro.rb
  #
  # Reproduces: [ERROR : vws-i] VWS error: E2EE/DAVE protocol required
  # Requires: gem install discordrb

  require "discordrb"

  bot = Discordrb::Bot.new(token: ENV.fetch("DISCORD_TOKEN"))

  bot.ready do
    channel_id = ENV.fetch("CHANNEL_ID").to_i
    puts "Attempting to join voice channel #{channel_id}..."
    bot.voice_connect(channel_id)
  end

  bot.run
