[WDMAUD.DRV] Allow enumerating only present audio devices

oleg-dubinskiy · oleg-dubinskiy · commit ff7bf747bf3a · 2025-04-06T17:29:45.000+02:00
- Avoid unnecessary enumerating audio-related device interfaces which are currently not present in the system.
- Do this for MMixer routines, same as it's already done for Legacy ones.
