Well , I ve been serching every where but could not find a solution to my problem , wish someone has one..

Well , I am using Gnome 2.8 on Debian.I ve a creative soundblaster live 5.1 card and 5.1 speakers.I use Alsa (emu10k1 driver) and xmms to play mp3 files like many others do.

Whenever i mute the gnome system sound and xmms ' sound , i can still hear it from my back 2 speakers.And when i try to turn the volume on , only the sound coming from front speakers increase. And wheni turn it down , only the front speakerssound decrease.

I have tried to configure my alsamixer.There are lots of channels on it but when i turn of three of them , i can mute the sound.(pcm , wave surround and wave center).

All I want to do is , make all the sound mute when i press my mute button on my keyboard and increase or decrease all the sound by pressing the increase or decrease button.

What i need is something that will control those 3 alsamixer channels .Or something else that will do the job...

Is there a way to do that?

Thanks alot for now...

My computer does something like this to. only the pcm level controls the volume (no surround enabled) but wave channels would be pcm as well. I use aumix to adjust the pcm level:

mute:

aumix -w 0

up:

aumix -w +10

down:

aumix -w -10

I set my system up to run these commands when I press my media keys.

First of all , thanks for your reply johnson_steve..

I ve tried to run the mute command that u said from console , but still the same thing happens.I still can hear the volume from the back 2 speakers and the center speaker.

I think there must be an "alsa" way to do that..

Thanks again...

try this

mute:

aumix -w 0 && aumix -W 0

if you end up finding a way to remap the thing with alsa let me know

Still the same thing, it only mutes the front left and front right speakers..
I ll let you know if i find a way to do that, dont worry..
Thanks..

Try this, I think will work...

to mute:

to unmute:

you can also put a number after PCM ( use range 0..100 ) for the regulation of the volume...


Yatta!!!

well , i ve used the commands you told , it works but mutes or unmutes only the front 2 speakers..
I can still hear the sound from the back 2...
You can see what i are the messages after i used those commands

As i said before there must be an "alsa way" to do that.. or an amixer command to mute or unmute all 5 speakers..

Thanks for the help though..
