realtek alc662 3stack-6ch -- NO 5.1 only stereo

[gdoteof]

I have a Vostro 220 from Dell, E7300. Realtek ALC662 integrated 5.1 audio. I could not get the sound working but eventually found
ALSA Upgrade Script which got my sound working.

Now, I am trying to hook up my 5.1 but am only getting 2 channels. I have tried

Oh yeah: Ubuntu 8.10 64 bit version

have you rebooted each time you edit the "alsa-base" file to make it take effect....
also try adding "index=0" to the end of the file ie

options snd-hda-intel model=3stack-6ch index=0

to give it first priority
and also after trying the snd-hda-intel options and rebooting goto the speaker icon on top panel right click >open volume control> preferences > tick all options... in this volume control look at > playback and in any other tabs look for switch... something like spdif (forget exact name ) and tick it... there may be other switches just experiment... i remember reading something about this before,..well i hope this is of some help

I had a similar problem where I only got 2-channel sound out of my Audigy card. I solved it by editing /etc/pulse/daemon.conf.

; default-sample-channels = 2
uncomment the line and add more channels. I put a 4 there, but I guess you would need a 6 for 5.1

After a reboot the issue was solved.

I was so excited to get two responses of things I haven't tried but neither worked. =(

I have rebooted after each edit of alsa-base.

[neu2buntu]

have you tried the iec958 switches to see if they work? also have you looked at the settings in > syste3m > preferences > sound and check that you have alsa mixer as default (sometimes the settings here override the other mixer in panel)

[gdoteof]

yes they don't seem to do anything. it is the s/pdif output (i think) which comes out of my mother board but i am not using it

In my case I have to adjust the volume on "PCM Center", "PCM Front", "PCM LFE" and "PCM Surround" to get anything out of the other speakers. I noticed that you did not have them available in your volume control. See if you can enable them and unmute them.

i had it there before, i had changed it just trying to fiddle with it

Sorry, I am out of ideas.

But I found the link to the page that helped me to get my surround working.

Perhaps it can help you. GL
