This is the only fully documented method I am aware of.

Technically the correct method of setting the default audio device in OS >= Win98 would be using the SetupAPI Functions when the audio device is installed using the SetupPreferredAudioDevices keyword in the driver INF file. The Microsoft philosophy regarding default audio playback/record is that it should not be changed progmatically by user applications. I guess my point was that modifying the registry directly was less of a hack when OS is XP or less.

Well, the author was simulating keystrokes to navigate/invoke Windows XP >= control panel extensions. For that reason, I have not tried to reduce everything to its most abstract state, but rather just presented a clear example of a method which can be used as a guide to design your own specific solutions to similar problems. The value of this coding example is the compact and generic method it demonstrates for acquiring the handles to the various controls in the applet from Managed C++.Ĭlearly, this example is specific to a particular task and applet. cpl files.Īs you can see, the concept is extremely simple.

exe files, everything else is the same as for. Only the launching method is different for.

A drop down list appears showing the audio output devices available on your machine for sound playback. Launch the "Sounds and Audio Devices Properties" applet from the Control Panel, go to the "Audio" tab, and click on the "Sound playback" combobox. The first thing you need to do is determine which two audio devices you want to switch between. The solution is small enough that its adaptation to other applets (. This general method can, of course, be extended to manipulate any applet or application, it's not limited to just the "Sound and Audio Devices Properties" applet. Changing the audio device this way is better (in my opinion) than directly modifying the Registry, which is always error prone because it's never exactly clear which Registry keys are involved. The panel actually appears on the screen briefly, but that's not a problem. We programmatically launch the "Sounds and Audio Devices Properties" applet and manipulates the panel using the messaging system. OK, having those four caveats out of the way, here is the general idea. Because we are switching between audio devices, and the actual audio devices available on your machine are almost certainly different from my machine, you must supply a bit of machine dependent information to get the solution to work on your own computer.

I'm not aware of any reason why the solution will not work under Vista, but verifying the solution's operability under Vista is left as an exercise for the reader. Your own applications don't have to mimic this limitation (wink).

Any third party application which outputs to the sound playback audio device, such as the Windows Media Player, has to be re-launched after the audio device has changed, because they usually consult the Registry and configure themselves only once at application launch time.

Precisely because Microsoft did not want you to do this, this solution is by definition a kludge, a workaround.

Backgroundīefore going further, a few things should be stated: This is a Managed C++ solution (.NET), but the method used here can be adapted easily to other languages. Have you ever wanted to switch the active audio output device (sound playback) on your Windows computer programmatically? Have you noticed that Microsoft (by design) has made it almost impossible to do this? Well, here is a solution to that problem.
