[help] Any way to detect a audio mixer change?

Recommended Posts

zone97

I have a script that creates hot keys for volume change. It works perfectly, except when the mixer changes. IE: if im using the built in sound card then plug in an HDMI cord and the audio changes to the hdmi, I have to close and reopen my script to get it to work again. What I would like is the program to detect when the mixer changes and restart. anyway this can be done?

That script will never work to do what you want. GUICtrl* functions only work on AutoIt created controls running in the same script. Then you have the option set GUIOnEventMode, but you don't have a GUI. Then you're using GUIGetMsg, which even if you had a GUI wouldn't work because you have OnEvent mode set and you can't use both in the same script at the same time.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
