Adjusting master volume

[Kerno]

Hi,

I have searched this and other forums and I am unable to find any code that works correctly, I am trying to detect if the users volume is set to mute and if it is I want it to turn the sound on. I also need to adjust the volume levels.

I have found this code that toggles the mute on/off but I need to detect if it is already muted

I know it has something to do with API's but I am not sure how to access these

Thanks for your help

Good morning Kerno

There's a piece of code here from KeepITCool which seems to work like a treat. Copy it into an empty module, and use this formula to call it :
=GetMasterMuteState()

Hi dominicb,

Thanks for your reply, the code to adjust the volume up or down works great but I cannot seem to get the code to check the mute state,

to call the function but i get a series of compile errors stating
'User defined type not defined' for the following

Dim mxc As MIXERCONTROL
Dim mxl As MIXERLINE
Dim mxlc As MIXERLINECONTROLS
Dim mxcd As MIXERCONTROLDETAILS
Dim mxcdMute As MIXERCONTROLDETAILS_BOOLEAN

do I need to add any additional 'References' to accept the MIXER types above

Thanks for your time

No, you don't need need to check any references, but you do need all the additional code that comes before the actual function. Thiis states all the constants that are required and cals the APIs to find them. Here, with all due credit to KeepITCool, is the code from this thread :

Use this to call it from VBA, which will return the boolean value of TRUE / FALSE.
