Hello, everyone: I'm trying to enable sp/dif (digital) output with my new Fedora Core 4 (x64) install, and I'm having a heck of a time trying to get it to work. Here's my basic setup: * Gigabyte K8VM800M motherboard * Realtek ALC655 on-board audio * Logitech Z-5500 surround speakers I'm able to get sound via the analog outputs without problems, but nothing comes from the digital output. As this is the first setup with digital outputs I've ever tried, I'm at somewhat of a loss were I should even begin. One interesting thing I did notice. My speakers have an lcd control panel which can show if it's detecting a digital signal or not. Normally, this shows "No Input Detected" when using the optical (digital) input on the speakers. However, after playing around in alsamixer, I noticed that if I changed the setting for IEC958 from "IEC958 In" to "Analog In", my speakers detect a signal, though there's no audio coming out. IEC958 Output is set to "00" (with no way to change it. IEC958 Playback AC97-SPSA is set to "100" (also, when I move this slider up and down, I hear an audible "pop" through the speakers). External Amplifier is set to "off," and I can't seem to change that setting either. So, I'm stumped. Any advice on how to proceed would be appreciated. Mark
