Hi Mitch,
I've tried out your suggestion, but I'm still unable to get the speaker
endpoint to be selected as the default endpoint.
Basically, my device has only 1 filter, with 6 pins, in the following order.
1. wave render pin
2. SPDIF-Out bridge pin
3. ac3 render bridge pin
4. wave capture pin
5. mic input bridge pin
6. speaker bridge pin
The filter is registered under KSCATEGORY_AUDIO, KSCATEGORY_RENDER and
KSCATEGORY_CAPTURE
The INF does not have the SetupPreferredAudioDevice entry.
What else can be done to get the speaker endpoint to be selected as the
default? Thanks for any advice.
KS

The class driver shouldn't interfere. When your driver installs, the
devnode will get a new "strong name", which invalidates the existing
endpoints. You can test this as follows:
1) Let the USB class driver install
2) Run mmsys.cpl
3) Dbl-click the SPDIF endpoint and change the name to "test"
4) Install your driver
5) Dbl-click the new SPDIF endpoints. It should have the default
name.

hi Mitch,
I've tried what you say, and also tried on a freshly installed Vista
System. On both system, I still end up having the SPDIF-Out endpoint
selected as the default endpoint instead of the Speaker endpoint.
As my device is a USB audio device, the MS usbaudio.sys driver gets loaded
once before I can install my driver. Would this be a reason why I just
cannot get the Speaker endpoint to be the default endpoint?
Are there any other way to specify to Vista which endpoint should be the
default? It would be nice if it can be specified in the INF file, just like
the way we can specify the default format to be used.

It sounds like you need to get rid of all the endpoint settings so you can
simulate a first install.
1) delete the contents of
HKLM\software\microsoft\windows\currentversion\mmdevices\audio\render
2) net stop audioendpointbuilder
3) net start audiosrv
For step 1 you will have to change the owner of the key to "administrators"
first.

Hi Mitchell,
I've tried
1) Reorder the bridge pins so that the speaker bridge pin is the last pin
2) Remove SetupPreferredAudioDevices from the inf
3) Both 1) and 2)
Nothing seems to have changed. I'm using a usb audio device that exposes
only speaker and SPDIF render endpoint, and the SPDIF endpoint is always
chosen as the default endpoint after installation on all 3 occassions. Using
the MS default usbaudio.sys driver gives the same result. Is there anything
else that I can try? Thanks.

Frank is correct that the speaker is chosen over headphones and SPDIF as the
default if no other endpoint has been explicitly set to be the default
(either by inf or the cpl). However, if your inf has a
SetupPreferredAudioDevices entry for these endpoints, then each will be set
in turn to be the preferred device and when installation is complete the
default device will be the last one processed. The processing order follows
the ids of the bridge pins. In other words if the SPDIF, speaker and
headphone bridge pins are 1, 2, 5, respectively, then the headphone will end
up being the default.
The solution is to remove SetupPreferredAudioDevices from the inf, or
reorder the pins.

The Vista heuristics should pick the speaker automatically. There may be
some problem in how your device is describing itself. For starters, you
should confirm that the form factor property (
http://msdn2.microsoft.com/en-us/library/ms679150.aspx) in the endpoint's
property store is Speakers.

Subject: [wdmaudiodev] How to set Default endpoint for Vista installation?
Hi,
I have an audio device which exposes a SPDIF, speaker and headphone
endpoints as rendering endpoints. Currently, after a fresh installation, the
headphone endpoint is always set as the default endpoint by the OS. Is there
any way in which I can specify for the speaker endpoint to be selected as
the default endpoint instead?
Thanks
KS
