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?


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?
