I don't have any other speakers set up, aside from the speakers on the monitor, but they use a headphone jack as well. the green one and the gray one are the jacks I use. [attachment=90816:6conn.gif]
It doesn't recognize: [attachment=90817:speakers-notification.png]
when anything's plugged in or out of the green jack, but it will tell me when I plug in and out of the gray jack. however, neither gives me sound. When I go to "manage audio devices," it tells me there I have nothing plugged in.
I'm running home premium, 32-bit. I've had it three years, the sound was fine up until a few days ago.
before having no sound, I missed an update to adobe flash player and uninstalled a codec pack for (I think) playing videos: http://shark007.net/vistacodecpackage.html
