Re: ATEasy driver for accessing Core Audio APIs from Windows XP/7

Hi,

Can someone help me?
I need to control the Master Volume and Audio Balance programmatically from ATEasy under Windows XP/7.
I've been busy studying the issue a little bit.
For Windows XP, it seems OK to use the winmm.dll library with the mixerOpen(...), ... , waveOutSetVolume(...) functions (nothing related to the Audio Balance, though), but for Windows 7, I don't see how can I use the MMDevAPI.dll... Importing this library to ATEasy and using its data types/procedures is an awful thing for me...

Any help/idea is welcome! Thank you.


Regards,

Paul T.

Never tried it either, but it looks like you need the functions from the AudioVolume interface.

Try importing in Audioclient.h as per http://msdn.microsoft.com/en-us/library/windows/desktop/dd316531(v=vs.85).aspx

Hi Victor!

Already tried this, but no use. Actually, it requires many more header files aside AudioClient.h, and after I manually set the path to them, I can't use any of the procedures described in the API. It imports me some structures having Procedures as their members and I cannot use them...



Regards,

Paul
