Audio Mixer Fails to Swap Audio Devices when Starting Game in PIE or Stand Alone Modes

Hi, I’m using UE5 v5.7.4 and I’m having issues with audio playback with my RME Babyface Pro FS interface. I can hear sounds perfectly well in the editor but I do not hear audio while testing my project using PIE or in Standalone. When checking the output log I receive this error message:

LogAudioMixer: Warning: FAudioMixerPlatformSwappable::CheckThreadedDeviceSwap PostDeviceSwap() failed

If I plug in headphones directly to my computer after the PIE is started the sound then works correctly in the headphones. Once I remove the headphones the sound then works properly through my RME audio interface. Closing the PIE and restarting results in no sound as before.

Any ideas on what may be going on and how I can fix it? Is there an option to prevent the engine from trying to swap audio devices? If that’s required then I wonder if I can get the engine to try again after it fails? I can supply my output log if that would be helpful, thanks!
