Out of curiosity, does it work to control the volume if autohotkey.exe is set to run in compatibility mode for WinXP SP2 ?

Great question. If it does work, I'll add it to the documentation.

I recently installed Vista and have installed AHK too.

I ran Rajat's Volume OSD for the test, with the mixer panel open.

If I run the script, it inserts a new application of which I can only control it's slider. If I compile, it is the same, but if I change the exe to XPSP2 compatability, it adjusts the speaker and all applications, just as if you grabbed the control with the mouse.

I'm glad you suggested this, as I had a couple other applications I was having trouble doing the same with. Girder, and Max10, for use with my mouse remote from X10.

Ran an additional test tonight for corrupt...

Set the ahk exe properties to run as XPSP2 compat, and now I can run the script as I could the compiled script's EXE.

Yes! The sound engine in Vista was completely re-wrote from the ground up.

As I understand it, the engineers behind it didn't follow the guidelines put in front of them, and were let go and replaced by new engineers that could think differently.

Previously, the sound engine was manipulated at the kernal level, now it is manipulated at the user level. Each app's volume can be adjusted independently of all others, whereas previously, you had the master and a single wave control for all apps, unless they programmed a seperate volume control within their own app. The Vista mixer is a new way of thinking for sure, and will take some getting used to.

Thanks for the info. I've revised the SoundSet page to read:

On Windows Vista, SoundSet and SoundGet affect only the script itself (this may be resolved in a future version). There are at least two ways to work around this:

1) In the properties dialog for the file "AutoHotkey.exe" (or a compiled script), change the compatibility setting to "Windows XP".

2) Have the script send volume-control keystrokes to change the master volume for the entire system. For example:

Send {Volume_Up}  ; Raise the master volume by 1 interval (typically 5%).
Send {Volume_Down 3}  ; Lower the master volume by 3 intervals.
Send {Volume_Mute}  ; Mute/unmute the master volume.

Revisions/improvements are welcome.

Oh? I'm able to control the volume just fine with SoundSet on Windows 7 with XP compatibility set for AutoHotkey.exe. However, Vista Audio Control Functions generally work better and with less side-effects.

I solved it with a dirty workaround:

; set Master Sound to 8 (from 50 which is max on my Lenovo T510)
Send {Volume_Down 50} ; go down to 0 (no matter what volume was before)
Send {Volume_Up 8} ; increase to 8

;set Master Sound to 40 (from 50 which is max on my Lenovo T510)
Send {Volume_Up 50} ; increase to 50 (no matter what volume was before)
Send {Volume_Down 10} ; go down to 40

You can use the VA.ahk library which can be found on the forums for anything newer than XP.

I like your little quick and dirty trick, although I suspect it is better to take the sound down to zero (0) before raising the volume.

If you max the volume and then shrink it, if the person is playing a file, it could be hazardous to someone's ear.
