I have a K8N NEO4 motherboard with a built in AC'97 sound card. It has a digital spdif output I wish to utilize.



My reciever is a Denon AVR 1709 which supports afaik DTS/AC3 in 44100 & 48000 hz. (It works with ATV2+xbmc+spdif/passthrough).

I have also fiddled around a lot in Unity, pavucontrol, the standard audio settings etc. Nothing seems to help.



At some points in my travels I have managed to get white noise out in the front speakers. I have also once managed to get normal stereo sound out once.



"speaker-test -c6 " sometimes (sometimes as with some certain settings) produces white noise in two channels (never all 6).



I dont have sound out from my normal 3.5mm stereo plugs either, neither front or back.



I have tried reinstalling alsa/pulseaudio many times, also reverting back to complete stock settings with no measurable successes.



Sorry about the images, I cant copy-paste the text properly formatted for some reason.



Is it possible something defaults to use the analog spdif instead of the optical?
Is there some idiot-safe way to get this working? Right now I would be happy to even have a reliable way to produce analog (3.5mm) stereo output just to make sure there isnt something fundamentally broken.

      I have also fiddled around a lot in Unity, pavucontrol, the standard audio settings etc. Nothing seems to help.



      At some points in my travels I have managed to get white noise out in the front speakers. I have also once managed to get normal stereo sound out once.



      "speaker-test -c6 " sometimes (sometimes as with some certain settings) produces white noise in two channels (never all 6).



      I dont have sound out from my normal 3.5mm stereo plugs either, neither front or back.



      I have tried reinstalling alsa/pulseaudio many times, also reverting back to complete stock settings with no measurable successes.



      Sorry about the images, I cant copy-paste the text properly formatted for some reason.



      Is it possible something defaults to use the analog spdif instead of the optical?
      Is there some idiot-safe way to get this working? Right now I would be happy to even have a reliable way to produce analog (3.5mm) stereo output just to make sure there isnt something fundamentally broken.

      I have a K8N NEO4 motherboard with a built in AC'97 sound card. It has a digital spdif output I wish to utilize.



      My reciever is a Denon AVR 1709 which supports afaik DTS/AC3 in 44100 & 48000 hz. (It works with ATV2+xbmc+spdif/passthrough).
