Disable/Enable Playback Devices

[Sori]

I need a way to disable/enable playback devices.

The method I use now is right clicking on the speaker icon, selecting playback devices. Right clicking on the device and selecting disable.

I want the same effect, but via coding.

I have found things such as disabling the drivers via device manager, but it seems that it does not work, or I don't know how to do it correctly.

I tried looking up APIs but not really sure which one would mess with such an item.

Any assistance would be much appreciated.

 

 

P.S.

Why?

Skype does not have an option to use the system default device. I often switch between my headphones and speakers. Through a bit of experimentation, I found that if you disable the device that skype is using, it will automatically fall back to the other device.

Try Registry in HKLMSOFTWAREMicrosoftWindowsCurrentVersionMMDevicesAudioRender.

There will be some devices and you have to figure wich one do you want.

Then inside each one you have a DeviceState, if you insert 1 you enable, if you insert 8 you disable.

Inside the device folder you will have another one called proprieties where the name of the device is there.

 

Windows 8.1 x64 ***EDITED***

I hope this helps.

Cheers

The registry edit appears to be working. If I disable my speakers, playback devices as well as Skype no longer see it as an option.

I will have to make the program and run some tests before I can fully verify.

Thank you very much ^ ^

Global Const $devHeadset = "{32337b5a-4178-4619-b2f3-79d8bf7598b4}"
Global Const $regPath = "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\"

EnableHeadset()

Func EnableSpeakers()
    ;Enable Speakers
    MsgBox(0, "Pre Speakers", RegRead($regPath & $devSpeakers, "DeviceState"))
    RegWrite($regPath & $devSpeakers, "DeviceState", "REG_DWORD", "1")
    MsgBox(0, "Post Speakers", RegRead($regPath & $devSpeakers, "DeviceState"))
    ;Disable Headset
    MsgBox(0, "Pre Headset", RegRead($regPath & $devHeadset, "DeviceState"))
    RegWrite($regPath & $devHeadset, "DeviceState", "REG_DWORD", "8")
    MsgBox(0, "Post Headset", RegRead($regPath & $devHeadset, "DeviceState"))
EndFunc

Func EnableHeadset()
    ;Enable Headset
    MsgBox(0, "Pre Headset", RegRead($regPath & $devHeadset, "DeviceState"))
    RegWrite($regPath & $devHeadset, "DeviceState", "REG_DWORD", "1")
    MsgBox(0, "Post Headset", RegRead($regPath & $devHeadset, "DeviceState"))
    ;Disable Speakers
    MsgBox(0, "Pre Speakers", RegRead($regPath & $devSpeakers, "DeviceState"))
    RegWrite($regPath & $devSpeakers, "DeviceState", "REG_DWORD", "8")
    MsgBox(0, "Post Speakers", RegRead($regPath & $devSpeakers, "DeviceState"))
EndFunc

According to the program... everything is changing.

According to Windows... Nothing has changed.

(I did also try to give RegWrite the full path without variables, yielding the same result)
