I have just fixed it. Don't ask why this worked, because I have no idea. I changed from coaxial spdif to optical spdif output on my frontend. The optical worked properly with AC3. So I changed back to coax to verify that this was the problem. The coaxial digital output then also worked properly! I am now unable to get it to fail, I didn't touch the cable from the coax output on the pc, and I used a diffeent input on the amp for the optical output. So really I haven't physically changed anything. maybe it's an intermittent fault with the onboard sound? I have noticed that smetimes if I use aplay to test 22khz file using the mixed-digital plug, the first time I play it it plays fast, if I repeat the excercise it is OK. weird huh?

I was having the same problem with my amp and dolby digital. I solved it by removing my .asoundrc file and using ALSA:spdif as the output device. Then go into KMix and mess with the settings until it works. I discovered this through pure trial and error, but it now works properly and I don't mess with it. Hope that helps.
