Exception occurred when decoding incoming audio data

Created by: maxymoo22

Summary

An exception occurs when DSharpPlus runs my VoiceReceived event handler. The error is along the lines of:

The given keys cannot be found in the dictionary at DSharpPlus.VoiceNext.VoiceNextConnection.ProcessVoicePacket(Byte[] data)

Details

I'm using the latest nightly build of DSharpPlus

Console output:

[2019-11-30 11:31:37 +13:00] [VNext RX] [Error] Exception occured when decoding incoming audio data
System.Collections.Generic.KeyNotFoundException: The given key '1' was not present in the dictionary.

Event fired.

System.AggregateException: Exceptions occured within one or more event handlers. Check InnerExceptions for details. (The given key '402299820825509899' was not present in the dictionary.)

   --- End of inner exception stack trace ---

The code I am using for the event handler:

static async Task HandleVoiceData(DSharpPlus.VoiceNext.EventArgs.VoiceReceiveEventArgs voiceData)
{
    if (voiceData.User.IsBot) return;
    Console.WriteLine("Event fired.");
    
    var stereoBufferArray = voiceData.PcmData.ToArray();
    foreach(byte b in stereoBufferArray)
    {
        bufs.Add(b);
    }
}

Where bufs is a: List<byte>

There is no other code in the event handler so far as I cannot get this part to work.

Notes

Every once in a while, no exception will be thrown. This usually happens when I don't have var stereoBufferArray = voiceData.PcmData.ToArray(); or the foreach loop in the code.

Also, in the second part of the error it cant find the key 402299820825509899 in a dictionary. I then realized that 402299820825509899 is my discord user id`
