Summary:

After joining a voice channel, if there is no outgoing audio (e.g., when you are not speaking) for three minutes, incoming audio (other speaking participants) will cut off and will only return if (a) you speak, (b) if you rejoin, or (c) if someone else joins.

Using standard Discord client does not cause this issue.

To reproduce:

Join Voice Channel > Be able to hear participants > Mute mic for three minutes > Participants are no longer heard

To be able to hear participants again, either (a) speak/unmute, (b) rejoin, or (c) another participant joins.

Things I've tried: Turn off idle detection, increase idle detection, force opus codec, use different accounts.

Workaround: Let your mic auto-unmute every 2-3 minutes for a brief duration (I use 50ms) using hotkey script.

Event log: Ends at "Voice WebSocket connected". No additional logs even when incoming audio is cut.

Version: 0.4.28 - 0.4.29 (Windows and Linux)

Theory: It could just be a problem with my internet refusing to stay in the connection properly if there is no data being sent. There is no issue with standard Discord client so this may not be true.

I tried this for 30 minutes and it didn't happen.

I should add that people have reported this at various times, but I've never been able to reproduce it.
