I'm looking for a way to automate the procedure of switching from one audio device to another. Typically, this involves going to the control panel --> sound and audio devices --> audio --> default device --> etc etc

Is there any way to create a script that will automatically change the device, run a particular program (for example, tv tuner software that is incompatible with my USB audio out), then change the audio device back to what it was originally...?

Any suggestions or help would be very much appreciated!

I actually use AHK for switching between my two soundcards.
My script is for WinXP, so if you have another OS, you may need to change window titles etc.

Great script procyon! Thx for sharing.
Sidenote tho, the !A-command is irrelevant as the simple enter-press does apply aswell as close the window. Makes it all slightly faster Smile

Also, why use the sleep-command when you will be waiting for the window to emerge anyway?

The most easy and non-obstructing way to do this is via RegRead and ReadWrite.

Windows stores the default playback device under the "HKEY_CURRENT_USER\ Software\Microsoft\Multimedia\Sound Mapper\Playback" key.

Doing something like this will switch between my onboard realtek and creative audigy se sounds cards that I have on my rig:

Thanks, this will help me when I get around to making a script that will detect when I plug my HDMI cable into my laptop and change the default playback device for me! Too bad I'm so lazy or I'd have done it by now Embarassed

I think this is pretty efficient. The sound dialog pops up, but for a split second only.

Here I've set it to F5 setting the first device on the list as default and F6 setting the second as default. Tweak it as needed.

I just updated to windows 7 and needed a toggle version of this script. I mixed and matched what I had with the above posts and came up with this.

This will set the first device active if it isn't already.
If the first device is active then it will activate the 3rd device.

Additionally once a device is picked it plays a sound so you know which device is selected.

Unfortunately playing with the registry didn't help me. I guess it is because I have a single sound card and I'm just trying to switch between 2 ports (front and back). So I went back to use the following GUI automation.

The function below takes "device" as it appears in mmsys.cpl and looks for it in the combobox. If it finds it it changes the device and returns true. Otherwise it returns false.

I do use the registry first, however, to check whether the current device is the one we are trying to switch to since, while setting the registry value doesn't change the real sound device, changing the sound device DOES reflect in the registry.
