[CA0106 - CA0106, playback] Background noise or low volume

[Kerry]

Sound has not worked since installing UBUNTU 12.04 while card and speakers worked fine under Win XP.
Have tried adjusting settings, speakers NOT muted, etc but no joy. Not sure what wrong.
Know I have Sound Blaster card. Also tried MoBoard jacks, still no joy.
I hear static from mouse scrolls, keystrokes, etc. as well as 'hum'/static through speakers. Sounds from songs, videos, etc. are preceptible but muffled even with volume high.

Appreciate support..
The issue is still that this system (Duel Core AMD Opteron 175 on MSI 7125 K8N Neo4 mobo) produces no sound in linux (UBUNTU 12.04 Kernel 3.11.0-18-generic) although sound fine on Winxp.

Did have soundblaster audigy sound card installed when reported this problem 2 days ago. Now, trying to resolve or at least make issue less complicated, removed sound card to try just the integrated, onboard sound (7.1 channel audio codec RealTek ALC850 Compliance with AC97 v2.3 Spec. Meet PC2001 audio performance requirement).

Still no sound (everything unmuted, speakers test fine).

Raymond I am having trouble with https://wiki.ubuntu.com/PulseAudio/Log
Maybe I don't understand the instructions...

"You have probably come here because you have a problem with PulseAudio, and someone asked you to provide a PulseAudio verbose log. Here's how to do that:

    Open a terminal, then enter these commands:

echo autospawn = no >> ~/.config/pulse/client.conf #use ~/.pulse/client.conf on Ubuntu <= 12.10
killall pulseaudio
LANG=C pulseaudio -vvvv --log-time=1 > ~/pulseverbose.log 2>&1

    Do what you need to reproduce the bug.

    Switch back to the terminal and press Ctrl-C to stop PulseAudio.
    Open your Launchpad bug and attach the file ~/pulseverbose.log (in your home directory) to that message.
    To return your system to a clean state again, edit ~/.pulse/client.conf with your favorite editor and remove the line "autospawn = no". If the file is now empty, you can just as well delete it. Then log out and log in again.
    Last but not least - thanks for helping out! "

Is that three seperate commands? i.e.
echo autospawn = no >> ~/.config/pulse/client.conf #use ~/.pulse/client.conf on Ubuntu <= 12.10

I tried:
echo autospawn = no >> ~/.config/pulse/client.conf #use ~/.pulse/client.conf on Ubuntu <= 12.10

and got:
kerry@kerry-MS-7125:~$ echo autospawn = no >> ~/.config/pulse/client.conf #use ~/.pulse/client.conf on Ubuntu <= 12.10
bash: /home/kerry/.config/pulse/client.conf: No such file or directory
tried:
kerry@kerry-MS-7125:~$ echo autospawn = no >> ~/.config/pulse/client.conf
bash: /home/kerry/.config/pulse/client.conf: No such file or directory

sorry... i am certainly doing something foolish but don't understand. very sorry.

[Raymond (superquad-vortex2)]

do you get sound from your CK804 analog output when using speaker-test ?

[Kerry (dad-5)]

No sound on speaker test. I am trying your pulse audio recommendation....

[Kerry (dad-5)]

Changed pulse audio configuration tab to Digital Stereo (IEC958) Output (also tried all others). With config set to (IEC958) the visual bar in pulseaudio moving to sound as I play audio file.. :), but still, no sound from speakers....... :(

[Kerry (dad-5)]

Notice in pulse audio when in Configuration tab i set to (IEC958) then go back to Output Devices tab the only "port" available in dropdown menue is "Digital Output (S/PDIF)" whaereas I have just the cheaper variety of speakers what use what I think are analog ports (like 9mm jack).

Other settings in configuration are analog and in Output Device tab allow analog outputs.

Maybe I need to try and buy S/PDIF speakers? Don't know when can get money for that...

[Kerry (dad-5)]

AMD 64 Dual 175 Opteron
MoBoard=MSI K8 Neo4 7125
Speakers: Just standard computer speakers. No amp or other audio device. Work fine in other operating system.
Removed Soundblaster Audigy (24 bit) which wasn't working anyway (with Linux) to maybe simplify as MoBo has integrated Realtek AC97 which is touted as caplable of 7.1 surround. Still, no luck.
.
While it has S/PDIF output jack, I don't have that kind of cable/speakers... just trying to use the small/standard (3.5mm) color coded jacks. Anyway... no output from those, analog outputs.

Sorry can't figure-out myself. Really have been researching on web for days 'til now wit's end. Thanks.

[Raymond (superquad-vortex2)]

you should open another bug if your ck804 is not working

how many audio jack do you MS-7125 have ?

it is strange to find channel mode if you have enough jacks at rear panel for output

Simple mixer control 'Channel Mode',0
  Capabilities: enum
  Items: '2ch' '4ch' '6ch' '8ch'
  Item0: '2ch'

[Kerry (dad-5)]

you should open another bug if your ck804 is not working
     Roger that. Sorry thought I was doing this right.. too new to understand

how many audio jack do you MS-7125 have ?
     It has 7 ( I can send .jpg, but bon't know how to this forumn... anyway

      O -- S/PDIF Out-Coaxial
Line In (in 7.1CH /6CH)---- O
Line Out ----- O
MIC ---- O

O ---- Rear Speaker Out (in 7.1CH /6CH / 4CH)
O ---- Center / SubWoofer (in 7.1CH /6CH)
[ ] ---- S/PDIF Out -Optical (in 7.1CH /6CH)

Again I could post photo... can I do that here?
THANKS! Please don't loose sleep over this just because I am!
GOD Bless

[Kerry (dad-5)]

"it is strange to find channel mode if you have enough jacks at rear panel for output"
   I appreciate the thought... trying to comprehend..

"Simple mixer control 'Channel Mode',0
  Capabilities: enum
  Items: '2ch' '4ch' '6ch' '8ch'
  Item0: '2ch'"

        Again... appreciate the thought, how can I understand/implement? (sorry I don't understand) Sorry dumb questions. Thank-you.

[Raymond (superquad-vortex2)]

The left 3 audio jacks are for 2-channel mode for stereo speaker output: Line Out is a connector for Speakers or Headphones. Line In is used for external CD player, Tape player, or other audio devices. Mic is a connector for microphones. However, there is an advanced audio application provided by Realtek ALC850 to offer support for 7.1-channel audio operation and can turn rear audio connectors from 2-channel to 4-/5.1-/7.1 channel audio. Line In ( in 7.1CH / 6CH) Line Out MIC S/PDIF O

if you have 5 audio jacks at rear panel, only need a channel mode control which change from 5.1 to 7.1 by retaskking line in jack

you need modification of patch_alc850 and alc850_update_jacks

to disable 2ch and 4ch of channel mode

[Raymond (superquad-vortex2)]

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/ac97/ac97_patch.c?id=4235a31784f59c9be5ff71534743c055091f9735

this patch add 8ch support of alc850 but your motherboard don't need those retasking of Mic jack since it have black and orange jacks

[Raymond (superquad-vortex2)]

you have changed the output to analog output of your Ck804 instead of ddigital output iec958

Six Jack Detect pins for automatic jack sensing

alc850 have three registers for Jack sensing

MX66 sense function select
MX68 Sense function information
MX6A Sense detail

[Kerry (dad-5)]

Thank-you. Trying to follow through these recommendation... little worried I will crash system or something since I am relative newbie to Linux. One benefit of problems is require me to learn more.

[Raymond (superquad-vortex2)]

does AC97 register 0x78 show the status of the jacks ?

does it change when you plugged and unplugged five rear panel jacks ?

0:78 = 1c8f
