I want to know why my "Stereo mix" input on my windows 7 does not pick up any sound, but sometimes it does, usually after a computer reboot once.
is there any software just like the windows volume mixer (right click the speaker icon > open volume mixer), but allows you to define keys on your keyboard to increase or decrease the volume of a program (and press multiple keys at once to lower one input and increase the other), and keys that you can press to auto-fade out an input (meaning, when you press it, it will mute the input but instead of just muting it, will slowly fade the slider down) and another key to do the opposite?
So it's like a audio mixer, only it is software-based on screen
In my experience, installing the Realtek CP and running through the audio config settings improved my sound quality and solved a few problems (like very low volume levels). I'm not saying it's guaranteed to solve your problem, just that it's worth a shot.
