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 (http://ubuntuforums.org/showthread.php?t=1046137&highlight=alc662) which got my sound working.

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

Any help would be appreciated!

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

[du@dde]

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.

[gdoteof]

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.
http://www.automaticable.com/2008-05-28/how-to-enable-surround-sound-on-ubuntu-hardy/

Perhaps it can help you. GL

[neu2buntu]

maybe "alsa-mixer" is the wrong device for using surround post a screenshot with the volume-control device pull down list open to see what options there are

[gdoteof]

unfortunately that tutorial did not work for me.

[gdoteof]

oops empty post plz delete

[gdoteof]

this?

[gdoteof]

Anyone else have a Vostro out there?

[neu2buntu]

hmmm your mixer options dont show any digital playback. im stumped here unfortunately, try this post it has extensive sound setup options and theres a section on surround too ,,,,
http://ubuntuforums.org/showthread.php?t=843012&highlight=markbuntu+pulseaudio+alsa+jack
the section about "digital output" may also interest you .pay attention to rebooting each time you try any of the digital switches also....

[gdoteof]

I'm not sure I have digital out at all? Isn't digital out a specific type of jack that isn't the same as the normal headphone style ones? If it is, I don't have it.. I will check out that link

[gdoteof]

Your ALSA information is located at http://www.alsa-project.org/db/?f=ee18b7d407f9a73214fc6986215fc61e03c9679d

SOOOOOOOOOOOOOOOOOLLLLLLLLLVVVVVVVVVVVEEEEEDDDDDDD DDDDDDDDDD

In my /etc/modprobe.d/options there was a line that said

options snd-hda-intel model=laptop

I replaced that with

options snd-hda-intel model=3stack-6ch-dig


I also recompiled and uninstalled alsa a million times but this is what fixed it.

[rb-cohen]

Wow, this actually worked! I can't believe how happy having 5.1 again has made me. Anyway, I did the following to get surround sound working with the Realtek alc662:


Followed the (simple) instructions at http://www.automaticable.com/2008-05-28/how-to-enable-surround-sound-on-ubuntu-hardy/

Added the line "options snd-hda-intel model=3stack-6ch-dig" to the end of /etc/modprobe.d/alsa-base

Restarted computer (for step 2 to take affect)

Opened sound preferences, selected ALSA mixer, ticked the newly listed "Center, LFE", etc.

Still under sound preferences, on the options tab I set 'Channel mode' to 6ch.

I used "$ speaker-test -Dplug:surround51 -c6 -l1 -twav" to test all worked, and it certainly did!


The key is step 2, the other steps are all well documented elsewhere.

[dasan]

it was enabled default for me only i need to do was select 6 ch from mixer

you can select it from command prompt too

type alsamixer in command and you will find a channel section select 6ch

[Eeqmcsq]

Thank you thank you thank you thank you thank you!!!
Thanks both to gdoteof for the original solution and rb-cohen for the solution that fit me best. Here's my test scenario for in case others with my motherboard need it.

This was tested using an Ubuntu 9.04 Desktop Live CD, so you can test it before permanently making changes to a real installation.

Motherboard: Zotac GF8200-C-E (aka GeForce 8200 ITX)
Sound: ALC662

1. From a terminal, type "gksudo gedit /etc/modprobe.d/alsa-base.conf". At the end of the file, insert the line "options snd-hda-intel model=3stack-6ch-dig". Save and quit out of gedit.
2. Force the alsa sound library to reload: "sudo /sbin/alsa force-reload". The Volume Control app will probably report that it has crashed. Just click Reload to reload it.
3. Open the Volume Control app, click Preferences. Check Surround, Center, LFE, and most importantly, Channel Mode.
4. Now go to the Options tab. For Channel Mode, select 6ch.
5. Type "aplay -L" to list all available devices. You can pick one of these devices when using the "speaker-test" command.
6. Run a 6 channel speaker test: "speaker-test -twav -c6 -Dsurround51:CARD=NVidia,Dev=0". The 6 channels will come out of the 3 audio jacks in the back of the motherboard.

Other notes:
- If you want pulseaudio to work in more than 2 channels, follow the link in step 1 of rb-cohen's instructions.

So...
I'm wanting to buy this board from newegg. Have you had any other motherboard centered issues? Any other workarounds? Did the SATA recognize and flow without a IDE hard drive?

Thanks in advance for your time.

The instructions in post #23 worked on my Zotac Ionitx-A-U in Xubuntu 9.10.

[mi.k]

Unfortunately post #23 does not work on my ZOTAC IONITX-D-E - NVIDIA ION. I am trying to check Check Box "Channel Mode" (in gnome-alsamixer), but after restart check box is again unchecked :(

Many thanks in advance for your time. Mike

[djmaxmalta]

it was enabled default for me only i need to do was select 6 ch from mixer

you can select it from command prompt too

type alsamixer in command and you will find a channel section select 6ch

by using the quoted method and without retating my wubi, i used terminal with "sudo /sbin/alsa force-reload" gave it my pasward and let it do its work, when terminal was ready i restarted rythembox


and bam my 5.1 labtec Arena 685 all worked (better then in windows)
