<div>I had a heck of a time getting SPDIF to work as well. Turns out that my ATI chipset was not supported by default int he Fedora Core 6 rpm install of ALSA. So I had to go to the ALSA website and download/install from source with a "--" option that turned on ATI support.
</div>
<div> </div>
<div>Once I had that done, I had to unmute the IEC958 in alsamixer, then turns it's volume to zero - AND - I had to umute IEC958P and set it's volume to 100%. I've never seen any documentation note the IEC958P so I guess it's unique to my chipset.
</div>
<div> </div>
<div>if you have an ATi chipset let me know, I have the instructions on how exactly I got mine working written up somewhere - I'll dig it out for you.</div>
<div> </div>
<div>Now that it's working though, the sound is beautiful. MythMusic even splits my MP3's into a surround-sound like effect despite the fact they are only in stereo. I have no idea why or how it does this as I didn't configure my alsa setup to do anything of the sort (I used defaults all the way through).
</div>
<div> </div>
<div>My only complaint is that at times, when I fast forward or rewind I'll lose sound. Pausing and resuming play fixes it. Sometimes I get some pretty loud crackle when pausing and resuming too. I'd love to know how to fix that as it annoys the girlfriend to death.
