Mitch,
I wonder if you could tell me how to differentiate between multiple
endpoints of the same type, say a card with four or eight general
purpose line inputs? I'd like to be able to call them Line Input A,
Line Input B, etc., or some such thing that correlates with the
physical input connectors.

driver wave devices
Device names, or more correctly "Audio Endpoint" display names are
derived from bridge pin friendly names. These friendly names come from
"Name" GUID in the KSPIN_DESCRIPTOR of each bridge pin. If you are
writing an adapter driver, then this is in your PCPIN_DESCRIPTOR tables.
The "Volume Control" string corresponds to the name GUID
KSAUDFNAME_VOLUME_CONTROL. You should probably change that to
KSNODETYPE_SPEAKER.
Here are our recommendations for the pin categories and names of bridge
pins that represent jacks or USB endpoints:
For speakers:
category = name = KSNODETYPE_SPEAKER
For headphones:
category = name = KSNODETYPE_HEADPHONES
For microphone:
category = name = KSNODETYPE_MICROPHONE
For line in or out:
category = name = KSNODETYPE_LINE_CONNECTOR
For SPDIF in or out:
category = name = KSNODETYPE_SPDIF_INTERFACE
For headset microphone:
category = name = KSNODETYPE_PERSONAL_MICROPHONE
For headset earphone:
category = name = KSNODETYPE_COMMUNICATION_SPEAKER
WRT to the last 2, note that in Vista, the following 2 lines have been
added to ksmedia.h
#define KSNODETYPE_HEADSET_MICROPHONE KSNODETYPE_PERSONAL_MICROPHONE
#define KSNODETYPE_HEADSET_SPEAKERS KSNODETYPE_COMMUNICATION_SPEAKER
In Vista it is important that you get the pin categories correct because
it determines what and how devices show up in the audio APIs, control
panel, etc.

Subject: [wdmaudiodev] Vista Build 5270 + friendly names for audio
driver wave devices
Hello,
I have just tried Vista again to see wether the devicename issues have
beed fixed or not.
It seems that the friendly names are not set automatically. All devices
are named:
"Volume Control"
If you open a Windows audio app (e.g. Wavelab) you can select the audio
device from a list of devices which are all called "Volume Control".
The funny thing is that you can change the name of each device if you go
to:
Control Panel -> Sound and Speech Recognition ->Audio Devices and Sound
Themes -> Audio Devices
By double clicking on each device I'm able to set individual
devicenames.
My question is if it is possible to set the devicesnames from the
beginning within the driver or the .inf file.
The friendly names which are also set in the registry are not recognized
by vista.
thanks,
Uwe
