Toggle "Mute" for Line in

[XmangiaX]

My co worker and I share speakers through our line in's. So if I want to listen to what hes playing I unmute my line-in. If I want to listen to my winamp I mute his line in. I was wondering if there is a way to toggle the little mute box with a handy little script.

Any ideas?

Thanks for any assistance given.

I have this piece of code:

; Get Wav Sound Volume
; Author gafrost

#include <GUIConstants.au3>

MsgBox(0,"", _SoundGetWaveVolume())

Func _SoundGetWaveVolume()
    Local $WaveVol = -1, $p, $ret
    Const $MMSYSERR_NOERROR = 0
    $p = DllStructCreate ("dword")
    If @error Then
        SetError(2)
        Return -2
    EndIf
    $ret = DllCall("winmm.dll", "long", "waveOutGetVolume", "long", -1, "long", DllStructGetPtr ($p))
    If ($ret[0] == $MMSYSERR_NOERROR) Then
        $WaveVol = Round(Dec(StringRight(Hex(DllStructGetData ($p, 1), 8), 4)) / 0xFFFF * 100)
    Else
        SetError(1)
    EndIf
    $Struct=0 
    Return $WaveVol
EndFunc;==>_SoundGetWaveVolume

It's for GET and not SET volume, so take it as way to go on...

I will play with this code to see what I can come up with.

Thanks, but Im looking for a toggle for mute on "LINE IN" and not a volume level number. We each have our own volume controls. Is it possible to do what I want?

I know about LineIn WAV differrence.

My example was for you as start for searching.

WINMM.DLL has these functions:

so you must start search MSDN and look for right one ...

Thanks again!

I found some usefull links about mixer:

I think best one is commandline utility volumeline - from the above last link.
