Hi All,

I have just installed a clean copy of Fedora Core 5,...and seem to be having problems with the S/Pdif "Headphone outlet". No sound is coming out from the damn thing !! and the funny thing is that my onboard speakers work fine :confused: I have been trying to find a solution to this for the last two days and have nearly given up all hope. So now its up to you guys/gals to help me solve this....

I dont know much about your hardware setup. I experienced sound problems with clean FC5 install. The best thing to do would be goto http://www.alsa-project.org/ find your sound card and see what problems have been reported. Downloading the lastest ALSA may help solve your problem.

Does your motherboard uses nforce chipsets? On my Asus a7n8x deluxe I installed the nforce drivers from nvidia (the nvsound module) and s/pdif works fine. I know it's an oss driver but it works fine for me.

I dont know why but it seems to have detected two devices.

1:Intel Hda using the Alsa mixer
2:Realtek ALC880 using the oss mixer

Both have the same effect on the S/pidf output.

This is my audio card :
00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04)

Then, as SouthPaw suggested, you might want to try the latest alsa drivers from the alsa project website.

I finally got this to work.

This is what I did.

1. Got the latest alsa devel drivers]
2. Installed them
3. After install do the following vim /etc/modprobe.conf

I commented out the old info I had in the file and pasted the lines below the comments.

#alias snd-card-0 snd-hda-intel ----old
#options snd-card-0 index=0 --old
#options snd-hda-intel index=0 --old
#remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r –ignore-remove snd-hda-intel--old
#Below is the new info
options snd-hda-intel model=z71v position_fix=1
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-card-0
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

Then reboot!!!
After reboot open a terminal and type alsamixer and check for devices that are muted and unmute.

It works like a charm
