Alsamixer extra volume control

Psyce · 2011-03-10 10:05:15

Hi @ all,

I got a problem with archlinux and the .asoundrc file. I want to create an extra volume control for MOC. This is my .asoundrc.

pcm.snd_card {
    type hw
    card 0 
    device 0
}

ctl.snd_card {
    type hw
    card 0
    device 0
}

# Das dmix-Plugin wird definiert.
pcm.dmixer {
    type dmix           # pcm.NAME: der Name jedes Gerätes kann angepasst werden
    ipc_key 1024
    ipc_perm 0666       # Andere Benutzer können ebenfalls dmix gleichzeitig nutzen
    slave.pcm "snd_card"
    slave {
        channels 2
    }
}

ctl.dmixer {
    type hw
    card 0
}

# Das dsnoop-Plugin, welches es erlaubt, mehrere Programme gleichzeitig aufnehmen zu lassen.
pcm.dsnooper {
    type dsnoop
    ipc_key 2048
    ipc_perm 0666
    slave.pcm "snd_card"
    slave
    {
        channels 2
    }
}

# Dies definiert unser Fullduplex-Plugin als Standard für alle ALSA-Programme.
pcm.duplex {
    type asym
    playback.pcm "dmixer"    #natürlich muss dann auch das passende Gegenstück angepasst werden
    capture.pcm "dsnooper"
}

pcm.!default {
    type plug
    slave.pcm "duplex"  
}
# phonon
pcm.phonon {
    type plug
    slave.pcm "phonon_vol"
    hint {
        show on
        description "Alsa" # Anzeigename in den Phonon-Einstellungen
    }
}

# phonon-Lautstärkeregler

pcm.phonon_vol {
    type softvol
    slave.pcm "duplex"
    control {
        name "phonon_vol"
        card 0
    }
}

# ctrl for phonon_vol
ctl.phonon_vol {
    type hw
    card 0
}

I have a onboard snd_hda_intel and usb headset. The USB Headset is the default sound output device without using .asoundrc.
Then I set up this .asoundrc file to get the extra slider to control the volume but alsamixer doesn't show it. After some testing why it doesn't show it, I thought ok letz switch the onboard as default card.

So I changed it in the .asoundrc file. What I got was soundoutput on my snd_hda_intel card without the switch but the usb headset was stil alsamixer -c0. When I used LMDE for a few days there it switched and showed everything extra control and hda_intel was alsamixer -c0. What I am doing wrong.

this is not a solution, but can you simplify your life. try pulseaudio is mature, DE-indipendent and updated with latest audio technologies (your usb headset)

this is only a suggestion

Can u add virtual volume controls to pulseaudio? Cause thats the issue i have atm.

i don't know about virtual devices, but pulseaudio goes over alsa, so pulseaudio add feature, and you continue also to use alsa features.....

I'm not sure this is related to your problem, but I have a system with a PCI soundcard along with a sound chip on the motherboard. Which sound device that would show up as Card 0 and Card 1, would change on almost every boot, until I modified some /etc/modprobe.d/ files.

If you install pavucontrol you get a mixer with a volume control for every program that uses pulseaudio.
