When bot is moved to another voice channel while playing, stops playing audio (code: 4014) #30
Description
Hi, when I move bot from channel to channel during active audio playback (doesn't matter if manually or via JDA) player is updated with a new endpoint, token, etc. but does not play audio.
I did a little digging in the code and noticed that this is due to the interception of the WebSocketClosedEvent event. Suggesting by error codes it appears that bot has disconnected from the channel (which is logical, since it connects to another one).
is Message.EmittedEvent.WebSocketClosedEvent -> {
// These codes represent an invalid session
// See https://discord.com/developers/docs/topics/opcodes-and-status-codes#voice-voice-close-event-codes
if (event.code == 4004 || event.code == 4006 || event.code == 4009 || event.code == 4014) {
logger.debug("Node '{}' received close code {} for guild {}", node.name, event.code, event.guildId)
// TODO: auto-reconnect?
node.destroyPlayerAndLink(event.guildId.toLong()).subscribe()
}
}

When I remove the 4014 code it seems to work properly (it does not remove the player and link, and player on the lavalink server is updated and playing audio)
if (event.code == 4004 || event.code == 4006 || event.code == 4009) {
logger.debug("Node '{}' received close code {} for guild {}", node.name, event.code, event.guildId)

This above solution is not very useful, because it won't capture in this way voice channel removed event, kicking bot from server event and finally doesn't remove player from the Lavalink server.
I wonder if the player is definitely updated with the new Discord sound gateway. My guess is that correctly one would have to delete player and create a new one. Is there any plan to implement changing the channel during audio playback function? If not how to handle this other than removing error code from if statement.
