I will be testing Oneiric my desktop machine to I see this issue are reproducable with latest Beta2 release. If not reproducable this issue, need fixing this problem only with Lucid branch.

Attila

Ok, I looked my desktop machine with latest Oneiric daily live CD.
The interesting think Oneiric producing equals issue with I experienced in Ubuntu Lucid 10.04.3 live CD. If I using my multimedia keyboard the volume up button, the volume meter right setted, and I hear sound.
The interesting think I compared the original generated amixer output and new generated amixer output after I increasing the volume, and diff not found differences the two text file.
Both two situation I generated following command the text file:
amixer >sound1.txt (this text file containing volume meters value before I not increased master volume)
amixer >sound2.txt (this file containing volume meters values after I increased master volume my multimedia keyboard volume button.

Attila

Ok, I looked again what volume meters are muted default when I booted
with Ubuntu 10.04.3 live CD.
I only doed following:
1. After the desktop presented my screen, I opened GNOME Terminal, and
ran amixer >sound1.txt command to store original mixer values with a
text file.
2. I launch Sound preference tool, and uncheck only the mute check box,
not increased volume meters.
3. I ran again with amixer >sound2.txt command to generate new changed
volume meters with an another text file.
4. I ran diff -u sound1.txt sound2.txt command to generate a diff style
output what volume meters status are changed from off to on after I
unchecked the mute checkbox in Sound preference tool.

I attaching the sound1.txt, sound2.txt, and
sound-volumes-differences.txt files.
To easyest your work, I copyed diff output:

After I done this three file generation, I reboot with live CD, and look
in terminal what volume meter status change resulting sound turning on
this sound card resulting I hear sound again.
When I ran amixer set 'LFE',0 on command, I hear sound again, because my
machine only have connected two speakers.

I experienced very similar issues with an other machine with Ubuntu
10.04.3 live CD, with an Intel N10 soundcard related, see Bug 867287
bugreport with following link:
https://bugs.launchpad.net/bugs/862287

With the Intel N10 sound card related little different volume meters are
muted by default, but amixer set 'LFE',0 on command result sound turning
on too if two speakers are connected this other sound card.
I try making a patch with merging this two bugreport fix with one patch.
When I done this fix, generating a custom live CD and testing two
machines the patch.
I attaching future this bugreport the patch, or the other bugreport?
What type fix you are accept future?

Attila

Hy,

Please review this patch.
I generated a custom Ubuntu 10.04.3 live CD with containing the patched alsa-utils script in /sbin directory.
When I booted this custom live CD, my Nvidia soundcard is not muted by default. I am absolute sure this patch will resolve the mute problem for an other bugreport reported Intel N10 soundcard too. I added both the Intel N10 soundcard experienced muted channels and the Nvidia soundcard experienced muted channels with the patch.

I have got a question if you accept this type fix with final patch and perhaps commit this fix Lucid and Oneiric branch:
What method are better to fix this problem? Use the switch_control method to only switch the muted status from off or on, or use the unmute_and_set_level method this new channels and setting for example with a 80% volume value?

Attila

I try assigning this bug, if you are reviewing my now sent patch, and perhaps tell me what can I need changing my patch to you final commit my fix.

I looked again a full updated custom Oneiric live CD what volume meters
are default muted, following volume meters are default muted with my
desktop machine this sound card:
Master, Headphone, Front, Surround, Center, LFE, Side.
I working now with an Oneiric alsa-utils package compatible patch.
I doed already the patch, but I would like testing my desktop machine
the result before I attaching this report.

Attila

I maked a patch for Oneiric alsa-utils package, with turns on following playback switches:
Front Playback Switch, Surround Playback Switch, Center Playback Switch, LFE Playback Switch, Side Playback Switch, Headphone Playback Switch

Please review this patch. I tested the patched alsa-utils package with my custom Oneiric live CD, and I hear sound by default after the live CD booted.

Attila

Hy,

Can I doed a mistake to fill Assigned field for me if I not have commit
permissions?
Anybody possible reviewing the attached patches and if this patches are
good committing proper repositoryes?
I make future similar patch for Precise related package?
I welcome doing the patch if anybody future will be reviewing.

I used the patched alsa-utils package for Lucid 10.04.3 custom live CD
with my J&W Minix M1200 netbook, with have built in Intel N10 type sound
card. Mute issue is not happening if I booted the modified live CD,
similar my desktop machine and other five machines with default
producing the described bug.
