Do you have mods enabled?

Description
I am running an Alienware 17 R4 - All drivers are up to date

When I launch HOI4, I have no music or sound. This happens during start up and during gameplay.

Logs report the following;

[09:37:58][pdx_entity.cpp:126]: Couldn't find sound effect: "infantry_move_animation"
[09:37:58][pdx_entity.cpp:126]: Couldn't find sound effect: "infantry_move_animation"
[09:37:58][pdx_entity.cpp:126]: Couldn't find sound effect: "infantry_rifle_attack"
[09:37:58][pdx_entity.cpp:126]: Couldn't find sound effect: "infantry_rifle_cartridge"
etc etc

I have removed all mods, and done a clean re-install - no change

When I rollback to Collie 1.10.5 - the music and sound works ok

I have no issues with music or sound when running EU4 or CK3 on the same PC

I have run DxDiag - no issues reported

I have also spun up a Windows 10 VM in the Azure Cloud - this has no issues running the same HOI4 build, so I suspect that this is hardware related.

Steps to Reproduce
Launch HOI4
