I have a project in UE5. When we use streaming to test it, audio plays as intended in both the device and the computer. When we deploy the app to the HoloLens 2 device there is no audio playing. We have checked that the audio has only one channel, even went step by step in the tutorial for spatial sound as described here: Spatial audio in Unreal - Mixed Reality | Microsoft Learn.
Any ideas are welcome.

Hololens doesn’t support Bink codec. You need to change compression type (in SoundWave asset settings) to “Platform Specific”.

I’m also experiencing the same issue in UE5.1.1. While changing the compression to “Platform Specific” worked for unreal 5.0, it does not seem to work in any 5.1.1 project. I’m not sure if the platform settings were not correctly set in the engine or what the deal is, but something seems broken. I’d love to hear if anyone has gotten Unreal 5.1.1 to successfully package a Hololens 2 project with working sound.
Have you gotten 5.1.1 to package a project with sound successfully?
Nope, I didn’t work with HoloLens in 5.1. Have you tried another compression options?
