Sound.au3 - _SoundVolume Returning @error 1

Recommended Posts

I've added this function to the Sound.au3 UDF

Func _SoundVolume($aSndID, $iVol)
    If Not( 0 <= $iVol <= 1000 And IsInt($iVol))Then Return SetError(2, 0, 0) ; invalid Volume Factor
    If Not __SoundChkSndID($aSndID) Then Return SetError(3, 0, 0) ; invalid Sound ID or file name

    __SoundMciSendString("setaudio " & $aSndID[0] & " volume to " & $iVol)

    If @error Then Return SetError(1, @error, 0)
    Return 1
EndFunc

It should change the volume of the audio file but it returns @error 1.

What am I doing wrong?

T0M50N,

I can only suggest that there is a problem using that command on sound files - it does state " Digital-video and VCR devices recognize this command", and not waveforms. :(

RazerM and I looked into providing a volume function many years ago (see >here) but as you can see decided that as it was not something we wanted to add for the same reasons as I mentioned above, even though that solution worked on sound files when tested. ;)
