When the game shows a recording but you cannot hear it, investigate output and playback before changing microphone input or reinstalling Packs.

Record a short, obvious line and note whether the game shows a saved take before changing the audio device.
Select the speaker or headphones you expect to hear, then restart after an output change before retesting playback.
Temporarily avoid Discord capture, OBS monitoring, virtual devices, extra adapters, and surround-routing changes while you test a basic speaker or headset path.
Repeat the same record-and-playback check in the No Gameplay Demo so Packs and game-mode settings are not part of the diagnosis.
OBS or alternate-output suggestions can be documented as experiments, but they are not a guaranteed or official solution.
Ready for a first round
Quick answers
Keep playback routing separate from microphone capture.
Next step
Install one known source Pack, restart, and run a short round before changing the rest of the show.
