Petty little question that I have been unable to find a solution for (if one exists)... I have set up different users for my kids on our Mac so that I can control their usage time, and when they are logged in they are almost always using headphones so I don't have to hear their annoying game sounds . They use a headset attached via a USB port. I like to listen via a set of speakers attached via the headphone jack. The issue is whenever I log into my user, I have to switch the output sound source. (They do too!) Is there a way to set a default source based on the user?
