Hello, gentle beings,
I've being plagued by this issue for years, both with XP and now Windows 7,
and, when I get around to upgrading, probably Windows 8 will offer no help.
It's wild that Microsoft never provides the opportunity to switch between
devices in the operating system using a hotkey, eh?
At any rate, I suggest the easiest solution is, at least in Windows 7, to
have the Playback Devices window open, and we could write a simple little
app to issue keystrokes to the list of available sound devices in order to
select the one you want, and then hit the "Apply" button to activate that
one.
I'm fairly new to scripting, and have done some pretty cool things working
with a free command-line utility to control Winamp from within the
Window-Eyes scripting environment, to set and retrieve bookmarks. This is
why I feel confident that Window-Eyes allows us to do pretty well anything
we want to do.
For me, it's just a matter of time before I learn the best way to switch
sound cards using Window-Eyes.
Good luck to all of us,
Rod Hutton

Thanks Bruce, but this doesn't seem to be related to sound cards and their
specific properties.
BTW, you may be interested to know that in the public beta, the async issue
of WMI which you were having seems to have been solved (although I don't
recall seeing it mentioned in the read me, s I thought I'd mention it ).

Hi Dave and Chip,
This is the standard format for a WMI inside a VBScript. If you have
Power
Shell then the format goes down to a single line command.
Do more search on this to get more properties detail on it.

Hi Dave,
I looked at this, or something like it, in the past and decided I couldn't
do it.
It might be possible to use WMI to do this, but I didn't know WMI well
enough.
If you aren't using VBScript, but you're using some language with access
to
all the Windows APIs, then you've probably got all you need to do it at
that
point, and you can forget WMI; but WMI was the only way I saw for VBScript
to do it.
Hth,
Chip
