According to my MB manual, they are both outputs. > Did you check the slider level for the IEC958? There's no slider. It can only be muted. As far as I know, you can't change volume level of a digital output. Volume control is done at the external amplifier. > Did you check to see if there is more then one IEC958 entry? There's only one.
