After Win10 Anniversary update, SetDefaultEndpoint (change default sound device) is no longer working

[fisofo]

Not sure if anyone knows what might be up, but I've looked around and haven't found anything yet. A snippet of the code in question is this:

Func _SwitchToDevice($sId)
    Local $oPolicyConfig = ObjCreateInterface($sCLSID_CPolicyConfigClient, $sIID_IPolicyConfig, $tagIPolicyConfig)

    Local $hResult
    $hResult = $oPolicyConfig.SetDefaultEndpoint($sId, $eConsole)
    If $hResult = $S_OK Then $hResult = $oPolicyConfig.SetDefaultEndpoint($sId, $eCommunications)

    Return $hResult = $S_OK
EndFunc   ;==>_SwitchToDevice

It *looks* like it is working, but the default sound device doesn't actually change. I'll attach my source code for anyone that wants to review it/help out. Code is courtesy Trancexx and KaFu.

Try changing IID_IPolicyConfig:

Global Const $sIID_IPolicyConfig = "{6be54be8-a068-4875-a49d-0c2966473b11}"

Thanks for the response and sorry for the delay! I expected an email notice and didn't get one.

In any case, doing that causes an error in the SetDefaultEndpoint line of "Variable must be of type "Object""

Prior, I had the variable set like this:

Global Const $sIID_IPolicyConfig = "{00000000-0000-0000-C000-000000000046}"

Any ideas?
