IsMute() for Vista - a start

[Steph]

Hi All,

I want a function to check whether a Vista computer is muted or not. I found this thread, which works on XP machines and started trying to adapt it for Vista. This is what I've got:

run("sndvol.exe","")
winwait("Volume Mixer")
$mute_query= ControlCommand ("Volume Mixer","","[TEXT:&Main Mute]","IsChecked" )
If $mute_query=1 Then
    msgbox(1,"","Audio is muted.")
Else
    msgbox(1,"","Audio isn't muted.")
EndIf
WinClose("Volume Mixer")

The problem is with the ControlCommand line, in the XP version the mute is a check box which can be checked, in the Vista mixer it is a button which I can find using the ControlCommand as shown above but can't check if it is checked or not, when you press it a small red x in a circle is added to the button, but it doesn't seem to be checked as such.

Any ideas what I could do next gratefully recieved.

Thanks,

Steph

Hi,

this works on XP SP2

$re = _isMute(1000)
If @error Then ConsoleWrite(@error & @CRLF)
ConsoleWrite($re & @CRLF)

    If $ex = True Then WinClose('[CLASS:Volume Control]')
    Return $retVal
EndFunc  ;==>_isMute

Thanks,

That's the same technique as in the thread I linked to earlier, unfortunately it doesn't work in Vista where sndvol32 has been replaced with sndvol and instead of a check box which can be checked for easily as in the code you posted there is a button. The button doesn't seem to have a pressed state, instead when you press it the picture changes as I describe in the original post. So I'm wondering if there is another way to check whether the sound is muted or whether I can check the button in some other way.

Thanks,

added this to audio.au3. Thanks Xenobiologist!

Beware that it is a semi-professionel solution and I only tested it on XP SP2.

Perhaps you can check for a certain pixel's colour?

If the picture changes, there must be at least one pixel which changes colour, so if you see what colour that pixel is in the muted and unmuted states, and then just use PixelGetColor, you'll know whether it's muted or not.

Hi,

using Pixel functions the window needs to be visible which is ...
