Hi there, happy new year

The original content of /etc/asounf.conf :

Code:

# ALSA system-wide config file
# By default, redirect to PulseAudio:
pcm.default pulse
ctl.default pulse

Well i want to configure my file /etc/asound.conf for my pc, i don't use pulseaudio, i just purge it, because i really don't like it.

i need :
1) Playback from Multiples Streams to my four speakers.
2) Control Volume for Each Application using the device
3) Capture for multiple devices (Mix, Mic, Line)

Reading -> https://www.alsa-project.org/wiki/As...rc_file_format

Code:

cat /proc/asound/cards
 0 [AudioPCI       ]: ENS1371 - Ensoniq AudioPCI
                      Ensoniq AudioPCI ENS1371 at 0xdc00, irq 19

Code:

i had put the follow on my new /etc/asound.conf :

Code:

pcm.!default {
    type plug
    slave.pcm {
        type softvol
        slave.pcm "plug:dmix"
    }
}

# Diviendo el sonido hacia las 4 Cornetas ( Surround 4.1 ) :
pcm.dshare {
    type dmix
    ipc_key 2048
    slave {
        pcm "hw:0"
        rate 44100
        period_time 0
        period_size 1024
        buffer_size 8192
        channels 4
    }
    bindings {
        0 0
        1 1
        2 2
        3 3
    }
}
pcm.frontx {
    type plug
    slave {
        pcm "dshare"
        channels 4
    }
    ttable.0.0 1
    ttable.1.1 1
}
pcm.rearx {
    type plug
    slave {
        pcm "dshare"
        channels 4
    }
    ttable.0.2 1
    ttable.1.3 1
}

pcm.mixin {
        type dsnoop
        ipc_key 5978293 # must be unique for all dmix plugins!!!!
        ipc_key_add_uid yes
        slave {
                pcm "hw:0,0"
                channels 2
                period_size 1024
                buffer_size 4096
                rate 44100
                periods 0 
                period_time 0
        }
        bindings {
                0 0
                0 1
        }
}

Well right now i don't had audio playback xD LOL

I want to configure too the equal for alsa but well i am confused xD which i should do now with this:

Code:

ctl.equal {
	type equal;
}

pcm.plugequal {
    type equal;
	slave.pcm "plughw:0,0";
}

pcm.equal{
    type plug;
    slave.pcm plugequal;
}

If you have no sound, let me point you to this on the page you shared:

Quote:

Neither the user-side .asoundrc nor the asound.conf configuration files are required for ALSA to work properly. Most applications will work without them. These files are used to allow extra functionality, such as routing and sample-rate conversion, through the alsa-lib layer. The actual reason that most applications will work without these user-side custom config files is that usually a default install of alsa-lib provides a sufficiently capable setup

You only have one device, which should mean it should be the default output. I have no .asoundrc/asound.conf, and everything works fine in ALSA with ALSA defaults, which includes mixing output from applications. I would start with an empty config file, and figure out why you have no output and go from there.

After i add the equal to the configuration file and restart, the sound works again with the most common applications except with wine xD.

Well i am deleting /etc/asound.conf and making "$HOME/.asoundrc" for the configuration

Code:

pcm.!default {
    type plug
    slave.pcm {
        type softvol
        slave.pcm "dshare"
    }
}

# Diviendo el sonido hacia las 4 Cornetas ( Surround 4.1 ) :
pcm.dshare {
    type dmix
    ipc_key 2048
    slave {
        pcm "hw:0"
        rate 44100
        period_time 0
        period_size 1024
        buffer_size 8192
        channels 4
    }
    bindings {
        0 0
        1 1
        2 2
        3 3
    }
}
pcm.frontx {
    type plug
    slave {
        pcm "dshare"
        channels 4
    }
    ttable.0.0 1
    ttable.1.1 1
}
pcm.rearx {
    type plug
    slave {
        pcm "dshare"
        channels 4
    }
    ttable.0.2 1
    ttable.1.3 1
}
control {
          # Definir el nombre del controlador de Volumen (Actualmente es PCM)
            name PCM
          # Establecer la tarjeta de sonido predeterminada (La 0)
            card 0
          #Arreglo para el sonido de bajo volumen
            min_dB -5.0
            max_dB 20.0
            resolution 6
}

pcm.mixin {
        type dsnoop
        ipc_key 5978293 # must be unique for all dmix plugins!!!!
        ipc_key_add_uid yes
        slave {
                pcm "hw:0,0"
                channels 2
                period_size 1024
                buffer_size 4096
                rate 44100
                periods 0 
                period_time 0
        }
        bindings {
                0 0
                0 1
        }
}

ctl.equal {
	type equal;
}

pcm.plugequal {
    type equal;
	slave.pcm "plughw:0,0";
}

pcm.equal{
    type plug;
    slave.pcm plugequal;
}

Dunno If i want volume control per application like in this screenshot of pavucontrol :

https://i.postimg.cc/ncGD7pD6/Pavucontrol.png

But using ALSA, why on internet everyone understand "How i can enable softvol plugin" instead "GUI for Volume Control per Application with ALSA"?
