Hey, my bot plays audio locally but I can’t hear it in Discord help?

Hi everyone! I’m working on a Discord bot called DMortal1 using @discordjs/voice, and I’m stuck on an issue where the bot seems to play audio fine on my end (logs say it’s working), but I can’t hear anything in the voice channel. There’s also a yellow "User maybe having trouble connecting to the call" warning next to the bot in Discord. I’ve been trying to troubleshoot this for a while and could really use some advice!

Here’s what’s going on:

- I’m running Node.js v22.14.0 on Windows, and the bot is hosted on my PC (IP: 192.168.4.29).

- I’m using @discordjs/voice (latest version), prism-media, and ffmpeg-static for audio.

- The bot joins the voice channel okay (signalling → connecting → ready in logs).

- It generates audio with ElevenLabs, and FFmpeg processes it (Audio buffer size: 72724, logs show Audio is playing! and Audio playback finished).

- But I can’t hear the audio, and I don’t see any "speaking" or "debug" events in the logs, so I think it’s not sending the audio to Discord.

- I’m using Opus encoding with FFmpeg (-f ogg -acodec libopus) and set inputType: 'ogg/opus' for createAudioResource.

const transcoder = new FFmpeg({
  args: [
    '-i', 'pipe:0',
    '-ac', '2',
    '-ar', '48000',
    '-f', 'ogg',
    '-acodec', 'libopus',
    '-b:a', '128k',
    'pipe:1',
    '-loglevel', 'debug'
  ],
  shell: false,
  path: ffmpegStatic
});
const outputStream = audioStream.pipe(transcoder);
const resource = createAudioResource(outputStream, { inputType: 'ogg/opus' });
player.play(resource);
connection.subscribe(player);

const transcoder = new FFmpeg({
  args: [
    '-i', 'pipe:0',
    '-ac', '2',
    '-ar', '48000',
    '-f', 'ogg',
    '-acodec', 'libopus',
    '-b:a', '128k',
    'pipe:1',
    '-loglevel', 'debug'
  ],
  shell: false,
  path: ffmpegStatic
});
const outputStream = audioStream.pipe(transcoder);
const resource = createAudioResource(outputStream, { inputType: 'ogg/opus' });
player.play(resource);
connection.subscribe(player);

I’ve got a hunch it might be a network issue, maybe my router or ISP is blocking UDP ports (50000–65535)? Another bot I use (Pulse) that’s hosted on a remote server works fine in the same Discord server, so I think it’s something local to my setup. I’ve tried a few things already:

Fixed an inputType typo (was ogg_opus, now ogg/opus).
Added debug logging for "speaking" and "debug" events, but I’m not seeing any output.
