I decided to update the library to the latest version which I did already, and there is an issue.\nTo thansmit the music data to the voice channel the bot is connected to, I just push the FFMPEG data output to the VoiceNext TransmitSink via TransmitSink.WriteAsync method. But now the is noting in the bot audio output. Maybe I am missing something and/or there is more to do with the workaround between FFMPEG and TransmitSink, but I cannot find any similar issues on the issues and discussions tabs.\n\n### What version of the library are you using?\n\nv5.0.0-nightly (make sure you are using the latest nightly!)\n\n### What .NET version are you using? Make sure to use the latest patch release for your major version.\n\n.NET 9.0\n\n### Operating System\n\nWindows 10\n\n### Reproduction Steps\n\nConnect the bot to the desired voice channel:\n```\nvar guild = CommandContext?.Guild;\nif (guild is null)\n{\n    return;\n}\n\nif (_guild != guild)\n{\n    return;\n}\n\nDiscordVoiceState? state = CommandContext?.Member?.VoiceState;\nif (state is null)\n{\n    return;\n}\n\nulong? id = state.ChannelId;\nif (!id.HasValue)\n{\n    return;\n}\n\nDiscordChannel? channel = await guild.GetChannelAsync(id.Value);\nif (channel is null)\n{\n    return;\n}\n\nTask\u003cVoiceNextConnection\u003e task = channel.ConnectAsync();\n_ = task.Wait(2000);\nVoiceNextConnection? Connection = task.IsCompletedSuccessfully ? task.Result : null;\nif (Connection is null)\n{\n    return;\n}\n\nwhile (Connection.TargetChannel is null)\n{\n    await Task.Delay(1);\n}\n\nwhile (true)\n{\n    try\n    {\n        Connection.SendSpeakingAsync(true).Wait();\n        break;\n    }\n    catch\n    {\n        await Task.Delay(1);\n    }\n}\n```\n\nPush the data to the transmit sink:\n```\nVoiceTransmitSink TransmitSink = Connection.GetTransmitSink();\n\n// The player logic is too complicated, and I tried to use the direct data preparation\n\nconst int durationSeconds = 5;\nconst int sampleRate = 48000;\nconst short amplitude = 15000;\nconst double frequency = 440.0;\n\nvar totalSamples = sampleRate * durationSeconds;\nvar pcmData = new byte[totalSamples * 4];\n\nfor (int i = 0; i \u003c totalSamples; i++)\n{\n    double time = (double)i / sampleRate;\n    short sample = (short)(amplitude * Math.Sin(2 * Math.PI * frequency * time));\n\n    int byteIndex = i * 4;\n\n    pcmData[byteIndex] = (byte)(sample \u0026 0xFF);\n    pcmData[byteIndex + 1] = (byte)((sample \u003e\u003e 8) \u0026 0xFF);\n\n    pcmData[byteIndex + 2] = (byte)(sample \u0026 0xFF);\n    pcmData[byteIndex + 3] = (byte)((sample \u003e\u003e 8) \u0026 0xFF);\n}\n\nusing var memoryStream = new MemoryStream(pcmData);\n\nmemoryStream.Position = 0;\nbyte[] buffer = new byte[3840];\n\nint bytesRead;\nwhile ((bytesRead = await memoryStream.ReadAsync(buffer)) \u003e 0)\n{\n    if (bytesRead \u003c buffer.Length)\n    {\n        Array.Clear(buffer, bytesRead, buffer.Length - bytesRead);\n    }\n    await TransmitSink.WriteAsync(buffer, buffer.Length);\n    await Task.Delay(20);\n}\n```\n\n### Trace Logs\n\n```log\nOn application start:\n\n[2025-10-04 12:49:30 +00:00] [DSharpPlus.DiscordClient] [Info]  DSharpPlus; version 5.0.0-nightly-02551+39527ed9f52a75c332df24d3b854e6f42d8751c9\n[2025-10-04 12:49:30 +00:00] [DSharpPlus.Net.Gateway.ITransportService] [Debug] Connected to the Discord websocket, using zlib-stream compression.\n[2025-10-04 12:49:30 +00:00] [DSharpPlus.Net.Gateway.IGatewayClient] [Debug] Received hello event, starting heartbeating with an interval of 00:00:41.2500000 and identifying.\n[2025-10-04 12:49:30 +00:00] [DSharpPlus.Net.Gateway.IGatewayClient] [Debug] Identified with the Discord gateway\n[2025-10-04 12:49:31 +00:00] [DSharpPlus.Net.Gateway.IGatewayClient] [Debug] Received READY, the gateway is now operational.\n\n...\n\nOn command execution:\n\n[2025-10-04 12:50:09 +00:00] [DSharpPlus.DiscordClient] [Debug] Timer accuracy: 10000000/50000 (high resolution?
