voice receiving ends with not apparent reason

[micr0tubule]

Summary

receiving voice works only for a short amount of time

Reproduction Steps

For reconstructing the problem join a voice channel together with the bot and start to speak until the voice data doesn't get printed anymore

Minimal Reproducible Code

import discord   
import io 
from discord.sinks import WaveSink as PycordWaveSink, Filters, AudioData
 
bot =  discord.Bot() 

class WaveSink(PycordWaveSink): 
    
    @Filters.container  
    def write(self, data, user):  
        if user not in self.audio_data:
            file = io.BytesIO()
            self.audio_data.update({user: AudioData(file)})

        file = self.audio_data[user] 
        file.write(data)     
        print(data) 


@bot.slash_command(guild_ids=[GUILD_ID])
async def join(ctx):  
    await ctx.author.voice.channel.connect()  
    await ctx.respond(f'listening to {ctx.author.name}', ephemeral=True) 
    bot.voice_clients[0].start_recording(WaveSink(), lambda x: x)     


bot.run(TOKEN)

Expected Results

continuous voice receiving until it gets manually stopped

Actual Results

the voice receiving ends after a short amount of time leaving no stacktrace at all

Still having this problem on both the release and the development version

It appears the voice client loses connection after not sending data so my solution is playing silence to keep the connection alive.

class SilenceAudioSource(AudioSource):
    def read(self) -> bytes:
        return b'0' * 3840

self.vc.play(SilenceAudioSource())
self.vc.start_recording(
