Dumb question time: Are you sure both jacks are outputs? Did you check the slider level for the IEC958? Did you check to see if there is more then one IEC958 entry? Did you try configuring mplayer to use the spdif output? You may want to post the output of "aplay -L" and "aplay -l". You may also want to try using aplay from the command line to play a sound file. A .wav file is a good choice. (aplay does not play mp3s.) From the web site: (with slight modification.) aplay -D ALSA:spdif something.wav Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
