How to unmute, muted middle speakers with 5.1 config?

[deathxxx123]

My sound card have alwayis muted middle sound with any distro by default. So I need unmute in alsamixer, but in this OS, does not have alsamixer. How to do that?

[deathxxx123]

Don't have amixer too.
Only have pulsemixer, but this program do not have ability to mute/unmute only Center speaker. Only can do that on all speakers, but that will not unmute the Center speaker.
Only Alsamixer and Amixer can do this.
Sound Card: Auzentech Prelude 7.1 (with Creative X-Fi [20K1] chipset)

I search for some help in the web and find something that can help:
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/677067/comments/4

I need add the:

[Element Center/LFE]
switch = mute
volume = merge
override-map.1 = center,lfe

To analog-output.conf , so i can mute/unmute just center/lfe from pulsemixer i guess.

But i do not see the:
/src/modules/alsa/mixer/paths/analog-output.conf

[deathxxx123]

I found how to clear this bug(enable alsamixer):
sudo pacman -S alsa-utils
Then i can open alsamixer in terminal and unmute my center speaker!
Also i found the analog-output.conf
in
/frzr_root/deployments/gameros-18_a89413e/usr/share/pulseaudio/alsa-mixer/paths
and add the

[Element Center/LFE]
switch = mute
volume = merge
override-map.1 = center,lfe

as root, save and exit. (because for my card, center channel is not called Center, LFE or CLFE like other cards, but it's Center/LFE instead. So, because that is missing in analog-output.conf , the center sound are always muted after clean install.)

After edit, analog-output.conf looks like this:

`
[General]
priority = 99

[Element Hardware Master]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

[Element Master]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

[Element Master Mono]
switch = off
volume = off

[Element Front]
switch = mute
volume = merge
override-map.1 = all-front
override-map.2 = front-left,front-right

[Element Rear]
switch = mute
volume = merge
override-map.1 = all-rear
override-map.2 = rear-left,rear-right

[Element Surround]
switch = mute
volume = merge
override-map.1 = all-rear
override-map.2 = rear-left,rear-right

[Element Side]
switch = mute
volume = merge
override-map.1 = all-side
override-map.2 = side-left,side-right

[Element Center/LFE]
switch = mute
volume = merge
override-map.1 = center,lfe

[Element Center]
switch = mute
volume = merge
override-map.1 = all-center
override-map.2 = all-center,all-center

[Element LFE]
switch = mute
volume = merge
override-map.1 = lfe
override-map.2 = lfe,lfe

[Element CLFE]
switch = mute
volume = merge
override-map.1 = all-center
override-map.2 = all-center,lfe

.include analog-output.conf.common`

Now i have center sound in 5.1 sound configuration!
SOLVED by Me! Hehe :)

I guess, you can include this:

[Element Center/LFE]
switch = mute
volume = merge
override-map.1 = center,lfe

in analog-output.conf by default, to fix muted center speaker for others who have Creative X-FI cards.
And also include alsa-utils package, so others can use alsamixer.
This will be great and unique update, because there are no other Linux distro, that have this!

I will include alsa-utils in the next release, but I am not sure how the proposed configuration will impact other users.

I think that will not harm anyone. If you edit the analog-output.conf to fix X-Fi cards Center, to get sound with 2.1, 4.1, 5.1, 7.1 and any configuration that uses Center/Subwoofer.
That is just miss mapping Center speaker for X-fi cards. Maybe the devs can finally add this in analog-output.conf by default, like other cards.
I can report the bug to Alsa-devs by myself, but i don't know where exactly i need to report.

[deathxxx123]

Great news. Looks like they will merge this change to pulseaudio or whatever.. So this cards will finally have a better support!

Closing since there is no further action to take. Thanks!
