I've been searching for days now trying to figure out how to solve this problem. I am running SuSE 10.1 and can't get any audio out of my spdif output. I know this topic has been covered before but none of the solutions work. The analog output works fine, I plug in my digital speakers in the orange output of the card and no sound. I tried alsaconf to reset my sound card and went through alsamixer, used kmixer to enable/disable Audigy Analog/Digital Switch, I've tried setting the IEC958 sliders to 0 as previously suggested, I've tried setting up alsa through xmms. I'm running out of ideas. As it stands now.. the only way I can get audio is through the analog outputs setting IEC958 Optical Raw switch off and Audigy Analog/Digital Output to ON. I hope someone out there has a solution to this frustration. I'd appreciate any suggestions. Thank you.

My setup is a bit different, but in order to get optical out of my hda mystique I had to mute the IEC958 L(loops) slider in alsamixer.
