How to find out which process and user is using the winaudio service?

Question

Windows Server

Good afternoon, sometimes a black screen is displayed on the terminal farm when the user logs in and that's it, restarting the win audio service helps. There is nothing particularly interesting in the windows log "Timed out (60000 ms) while waiting for a transaction response from the "Audiosrv" service.
How and with what can I monitor the service in more detail? (which process and user is using this service).
