Setting record mixer properties inside app

[billiam904]

I need to be able to automatically adjust recording mixer properties from inside my app such as making sure that "Line In" is selected versus Microphone or other device, set record volume to 50% and make sure left/right balance is set to 50%. I have looked at the mixer functions but n ot sure how to proceed. Can someone give me some sample code please? Thank you very much. Bill Dennis Orlando, FL
