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.

Code:
Run, mmsys.cpl
Sleep, 100
WinWait, Sounds and Audio Devices Properties
IfWinNotActive, Sounds and Audio Devices Properties WinActivate, Sounds and Audio Devices Properties
WinWaitActive, Sounds and Audio Devices Properties
Send, ^{Tab}
Sleep, 100
Send, ^{Tab}
Sleep, 100
WinWait, Sounds and Audio Devices Properties
IfWinNotActive, Sounds and Audio Devices Properties WinActivate, Sounds and Audio Devices Properties
WinWaitActive, Sounds and Audio Devices Properties
Send, {Down}
Sleep, 50
Send, !A
Sleep, 100
Send, {Enter}


As a sidenote - this script switches between two audio devices and I don't have a clue which device it would select if you have more.

SoundSet
--------------------------------------------------------------------------------
Changes various settings of a sound device (master mute, master volume, etc.)

SoundSet, NewSetting [, ComponentType, ControlType, DeviceNumber]

If this parameter is omitted, it defaults to 1 (the first sound device), which is usually the system's default device for recording and playback. Specify a number higher than 1 to operate upon a different sound device.


Might be of interest.
Cool

SoundSet only changes volume etc. of a selected device, but it does not change which device is active.

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:
Code:

; Toggle Sound Devices
!+s::
    RegRead, Device, HKEY_CURRENT_USER, Software\Microsoft\Multimedia\Sound Mapper, Playback
    if(Device = "Realtek HD Audio output")
    {
        RegWrite, REG_SZ, HKEY_CURRENT_USER, Software\Microsoft\Multimedia\Sound Mapper, Playback, Sound Blaster Audigy
        Device := "Audigy"
    }
    else
    {
        RegWrite, REG_SZ, HKEY_CURRENT_USER, Software\Microsoft\Multimedia\Sound Mapper, Playback, Realtek HD Audio output
        Device := "Realtek"
    }
   
    ToolTip, % "Sound Device: " Device
    SetTimer, ResetToolTip, 1000
return


; Clear the ToolTip
ReSetToolTip:
    ToolTip
    SetTimer, ReSetToolTip, Off
return



Change the "if(Device = ...)" line with your sound card names.

Unfortunately I haven't found a way to make windows update all the programs running with the new default sound card device. That way even if I change the default by hand I have to restart my processes to update them with the new sound device.

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
