I recently tried playing Clair Obscur for the first time, but there was no audio at all. After some troubleshooting, I managed to get sound by lowering my output device's sample rate from 384kHz to 192kHz. I've never faced this issue in other games, so I'm wondering if it's something specific to Unreal Engine 5. I tested another UE5 game, Indigo Park, and had the same audio issue, though Valorant (also built on UE5) worked just fine. Is there a way to fix this on my end, or is it something only the developers can address? Also, why might a smaller game not have this audio problem while a larger one does? Any insight would be appreciated.

Using a 384kHz sample rate could be problematic. Most modern audio setups don't reliably support high-quality playback beyond 192kHz. You might actually get worse audio quality with 384kHz compared to 192kHz, especially if you're using lower bit-depths. It's likely the silent games need better quality audio data or more channels, which could overwhelm your audio drivers. TL;DR: Stick to 192kHz or lower for better compatibility.
384kHz is overkill for gaming! That sample rate can handle complex signals like composite video, so it’s probably too much for these games to manage. Dropping it down to 192kHz should fix your issues.
Why are you even using a sample rate above 48kHz? For most situations, 48kHz is more than enough!
I mainly use it for high-fidelity music quality now and then.
