Summary0013178: Playback silently grays tracks or Freeze UI
DescriptionWhen Windows essential Audio Services are missing MWM silently fail to playback file and in worst cases freezes MMW UI.

Error it throws is "AUDCLNT_E_SERVICE_NOT_RUNNING", the services are called "Windows Audio" and "Windows Audio Enpoint Builder", both should be running as automatic.

We should throw Error dialog letting user know it have System wide problem with either driver and/or system Audio services.

For two users correcting "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Audiosrv\" Key "DependOnService" was set to contain only
"AudioEndpointBuilder
RpcSs"

and not third line with "MMCSS" resolved the issue.

For one user only way to fix this was to use "sfc /scannow" command as both "Windows Audio" and "Windows Audio Enpoint Builder" services was missing.

Forth user needed to choose non WHQL driver (strange but true) as Microsoft one had bad buffering DLL which resulted in artifacts when playing 24/96 FLAC files.
