Na rozchodnie soft. mixovania treba tento config pre ALSA:

# ~/.asoundrc
pcm.audiophile {
    type hw
    card 0
}

# ICE1712 dmix:
pcm.ossmix {
    type dmix
    ipc_key 1024
    slave {
    pcm "hw:0,0"
        format S32_LE
        period_time 0
        period_size 1024
        buffer_size 5120  # buffer size < 6653, but pow(x, 2)
        rate 44100    # we want to play CDs only
    }
    bindings {
        0 0
        1 1
    }
}

# This is what we want as our default device
# a fully duplex (read/write) audio device.
pcm.duplex {
    type asym
    playback.pcm "ossmix"
    capture.pcm "dsnooper"
}
#######################################
# Everything shall be dmixed, so redefine "default":
pcm.!default {
    type plug
    slave.pcm "ossmix"
    #slave.pcm "duplex"
}

# OSS via aoss should d(mix)stroyed:
pcm.dsp {
    type plug
    slave.pcm "ossmix"
    #slave.pcm "duplex"
}

ctl.mixer {
    type hw
    card 0
}

pcm.analogout {
    type plug
    ttable.0.0 1 # (Out Left)
    ttable.0.1 1 # (Out Right)
    slave.pcm ice1712
}

pcm.ice_spdif {
    type plug
    ttable.0.2 1 # (Out Left, 2)
    ttable.0.3 1 # (Out Right, 2)
    slave.pcm ice1712
}

V mplayeri treba nastavit softverove mixovanie:

cat .mplayer/config

softvol = 1
