I need to change volume balance every now and then as my headphones have the right ear too silent (while still very good in all the other criteria) while the built-in speakers are Ok. Unfortunately balance adjustment is hidden so deep in Windows 7 that it annoys me a lot to go there every time (it was much better in XP). Is there an alternative way to change it? Like a handy app just for this, a console/powershell command or a scripting way? I only need to switch between two states: normal and one biased.
UPDATE: Though I have accepted an answer, I am still looking for better alternatives as the app suggested is, as I have said, too unstable.
