gitadora: arena cab volume change prevention (#478)

## Link to GitHub Issue, if one exists
#477 

## Description of change
Arena cab has two sound cards and it uses `WrappedIMMDeviceCollection`
to set the volume to 100% on boot on both, instead of the typical
`GetDefaultAudioEndpoint`.

## Testing
Testing Delta, testing other games as well as they are affected.
