Hello,
I'm hoping that someone can help here.
I am trying to find the link between the Endpoint information used in a WDM
Audio Driver and the Audio Properties for an endpoint.
When the driver is installed, the AddReg section in the .inf file causes the
EndPoint names top be written to
HKLM\System\CurrentControlSet\Control\MediaCategories\{EndpointGuid}\Name.
The Audio Control Panel gets all its information using the MMDeviceApi which
gets all its information from
HKLM\Software\Microsoft\Windows\CurrentVersion\MMDevices\Audio.
There was a problem in our .inf file which meant that in the update to 1903 the
EndPoint Names weren't added to the registry. All endpoints were given a
default name of "Digital Output" or "Digital Input" in the Audio Properties.
This is now what is retrieved by the MMDeviceAPI and displayed in the Audio
Control Panel.
Reinstalling the driver with a corrected .inf file writes the names correctly
to the MediaCategories section of the registry, but the MMDevices is not
updated.
I'd like to write a simple command line program to correct the names but I can
see nothing in the information returned by the MMDevicesApi which links to the
MediaCategories section to be able to retrieve the intended names for the
endpoints.
Am I on completely the wrong path? Is there a better way of updating the
endpoint names in the MMDevices section?
Many thanks in advance
Ed Tottenham
