ALSA w/ ICE1724-simultaneously playback via analog & digital

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello List-Users,


..after some more hours with how-tos and man-pages I'm now able to hear
with the default wrapper directly to both devices (as written down
below) .. when I choose the dmixer-solution my audicious won't start to
play :\

..but how I'm gonna use dmixer with that solution to hear simultaneously
playback via analog & digital ??

I got no clues anymore... :\

Best regards,
Eike

my asound.conf at -this- moment...

1) generic device sets

*Code:*

pcm.snd_card {
    type hw
    card 0
    device 0
}

pcm.optical {
    type hw
    card 0
    device 1
}



2.1) default wrapper directly to both devices

*Code:*

pcm.!default {
     type plug
     slave.pcm dispatcher_2ch
     ttable {
       0.0
       1.1
       0.2
       1.3
     }
}




2.2) default wrapper directly to dmixer

*Code:*

pcm.!default {
     type plug
     slave.pcm dmixer
     ttable {
       0.0
       1.1
       0.2
       1.3
     }
}




3) dmixer

*Code:*

pcm.dmixer {
    type dmix
    ipc_key 1024
    ipc_perm 0666
    slave {
        pcm dispatcher_2ch
        period_time 0
        period_size 1024
        buffer_size 8096
#        rate 44100
    }
    bindings {
        0 0
        1 1
    }
}



4) dispatcher to bring up two devices in one

*Code:*

pcm.dispatcher_2ch {
        type multi

        # analog
        slaves.a.pcm snd_card
        slaves.a.channels 2

        # optical
        slaves.b.pcm optical
        slaves.b.channels 2

        # analog
        bindings.0.slave a
        bindings.0.channel 0
        bindings.1.slave a
        bindings.1.channel 1

        # optical
        bindings.2.slave b
        bindings.2.channel 0
        bindings.3.slave b
        bindings.3.channel 1
}




5) misc

*Code:*

ctl.dispatcher_2ch {
        type hw
        card 0
}

ctl.dmixer {
        type hw
        card 0
}
