Just hooked up a set of Dell AC411 speakers to my Dell Precision T7600. I know the speakers work because I can hear the tone when I press the power button off an on - (the light also comes on)
But no audio is coming out from the CPU through the speaker- both when I play audio or the speaker test tone
Have tried using the "devices and printers" but itt will not add the speakers there - or under the sound tab under control panel.
Our apologies that you have not received a response from our Audio users. Did you ever get this AC411 issue resolved?
