I`ve got Infrasonic Quartet PCI Soundcard and use Ubuntu 13.04.
The card has 2 analog stereo outputs. I use both outputs to connect my headphones and speakers to each other.
But I suddenly cannot manage the outputs with alsamixer: I can mute only Output 1/2.
Output 3/4 is always "On" whatever I change in Alsamixer.
Here is my /proc/asound/cards: 



0 [HDMI           ]: HDA-Intel - HDA ATI HDMI

                      HDA ATI HDMI at 0xf7e60000 irq 45

 1 [Quartet        ]: ICE1724 - Infrasonic Quartet

                      Infrasonic Quartet at 0xc080, irq 18


Can someone tell me how to make alsamixer manage both outputs ?



UPDATE.
Here is the amixer -c 1 scontents output:

Could anybody explain what this output means? Why playback channels are mono?



Here is my alsamixer screenshot:enter image description here
Output 3/4 is off but both outputs are playing sound now. And I can`t switch it off.

The problem is solved.
Thanks to CL. I tried to solve it with PulseAudio.
First of all I installed pavucontrol. Then I made ~/.asoundrc (Alsa config file) and pasted the following into the file :



pcm.pulse {

    type pulse

}

ctl.pulse {

    type pulse

}

pcm.!default {

    type pulse

}

ctl.!default {

    type pulse

}


It makes PulseAudio to be used by default.
And after that I can manage both outputs of the soundcard separately with pavucontrol. Now it`s possible. Finally Otput 1/2 is named Analog Output , Output 3/4 - Digital Output in Volume Control.
I used https://wiki.archlinux.org/index.php/PulseAudio/Examples#Advanced_ALSA_Configuration for information.
