record and play audio

I am trying to do https://github.com/discordjs/voice-examples/blob/main/recorder/src/createListeningStream.ts in v14 with this code:

function createListeningStream(receiver, userId, user) {
    const opusStream = receiver.subscribe(userId, {
        end: {
            behavior: EndBehaviorType.AfterSilence,
            duration: 5000,
        },
    });
    const decode = new prism.opus.Decoder({
        channels: 2,
        rate: 48000,
        frameSize: 960,
    });
    const filename = `./recordings/${Date.now()}-${getDisplayName(userId, user)}.ogg`;
    const out = createWriteStream(filename);
    console.log(`👂 Started recording ${filename}`);

    pipeline(opusStream, decode, out, (err) => {
        if (err) {
            console.warn(`❌ Error recording file ${filename} - ${err.message}`);
            throw err;
        } else {
            console.log(`✅ Recorded ${filename}`);
        }
    });
}

function createListeningStream(receiver, userId, user) {
    const opusStream = receiver.subscribe(userId, {
        end: {
            behavior: EndBehaviorType.AfterSilence,
            duration: 5000,
        },
    });
    const decode = new prism.opus.Decoder({
        channels: 2,
        rate: 48000,
        frameSize: 960,
    });
    const filename = `./recordings/${Date.now()}-${getDisplayName(userId, user)}.ogg`;
    const out = createWriteStream(filename);
    console.log(`👂 Started recording ${filename}`);

    pipeline(opusStream, decode, out, (err) => {
        if (err) {
            console.warn(`❌ Error recording file ${filename} - ${err.message}`);
            throw err;
        } else {
            console.log(`✅ Recorded ${filename}`);
        }
    });
}

I either cannot record correctly or I cannot play back correctly. I think I need the params to play back the file, or how to convert to a usable file. basicly do you know where I can get those for this setup because neither primsmedia docs nor the djs docs explain stuff what try to play the file that doesnt work: cat <file> | ffmpeg -f s16le -ar 48000 -ac 2 -i pipe:0 -acodec pcm_s16le -ar 48000 -ac 2 -f wav - | ffplay - sample recording attached
