Dual Soundcards

If I install two identical sound cards in my computer, is there any way
to separately identify them so that one Windows application would always
use one of them (the same sound card each time) and a different Windows
application would always use the other one?

And yes, this is relevant to a K3 application I have in mind.

Thanks es 73,
Dave AB7E

Re: Dual Soundcards

On my machine running WinXP Pro, Windoze identifies the two different sound
cards separately, and most sound software also has an option somewhere to
select the sound device. Only one of my programs doesn't let me choose the
device and I can't remember which one that is - I guess it just picks the
Windoze default sound device.

Two identical cards will probably be listed with the same name twice in
sequence in device manager, sound manager etc. One may perhaps have a (2).
Otherwise, you will just have to remember which is which.

It's good to be able to leave Windoze on the default sound card & speakers,
and MMTTY/MMVARI etc. using the extra sound card plugged into the K3. This
way, I don't transmit "You've got mail", or the "critical" noise when
something crashes. And these config settings are saved.

Yes, Windows XP will work with several sound cards. I can't answer for
Vista or Win7.

Re: Dual Soundcards

Yes, I agree that Windows will work with multiple sound cards, including
virtual ones like Total Recorder.

However, let's assume that I have two identical sound cards installed
... same manufacturer, same model number, same drivers, etc. Windows
shows both of them with the exact same title in Device Manager, and any
particular application will simply show both identical descriptions in
their respective drop down setup menus. Is there any way I can
separately identify them so that I can connect them to different
external hardware and know which is being used for what?

Thanks again,
Dave AB7E

Re: Dual Soundcards

Really good question. I installed a second sound card of the same type in my
computer recently, and expected to have this problem -- but for some reason,
it came up with a slight variation on the name, so I could distinguish them.
Nevertheless, I'd be very interested in any knowledgeable responses to this
query.

On the current version of Mac OS X, every sound device has a unique "device UID" that identifies the specific location of the device in the USB tree, Firewire port, or the built-in audio location of the sound card.

This unique ID is therefore persistent not just across sleep/wakeup cycles, but also through reboots. You identify a sound card once (e.g., plugging and unplugging it) and it is good "forever."

An example of a device UID on Mac OS X is

"AppleUSBAudioEngine:microHAM:microHAM CODEC:fa222200:2,1"

Windows must have the same thing. In both OS, you are however at the mercy of the software author whether he has implemented this level of detail :-).

Dave,

Bring up the mixer (volume control) and you can switch between the sound cards under
Options>Properties>Mixer Devices. Mute one and see if it works for the device you
want it to.

Round about, but should work. I think Windows will list them in the order they were
installed.
