I have a Fujitsu Siemens 3230T monitor, which offers HDMI input and can play sound, albeit badly, over internal speakers. There is also a 3.5 audio jacket that I thought was to direct the sound from the HDMI signal through to an external sound system.
As I have trouble getting sound to play over the external sound system (not understanding the menu structure), it leads me to suspect that it is not a line out but a line in audio jacket, so that one could play sound over the monitor's inferior internal speaker from an external source.
I am lacking a 3.5 to 3.5 cable so I cannot test myself to be sure.
Can somebody clear up if the monitor has a line in or a line out?
