I'm using 10.3.9 on an eMac. I'm also using external speakers. When trying to set the output sound device within System Preferences to either the built-in speakers or the external speakers I run into the following problem. If I don't have the external speakers plugged into the headphone jack the Preference sound output window will show the built-in speakers choice. However, when I plug in the external speakers that choice is replaced by Headphones-built-in audio. Does 10.3.9 allow for choosing between output sound devices? Mike Gantz mgantz at frontiernet.net
