via_82xx + 5.1 + Skype +mpd

Ok ppl hello.

I am trying for hours and hours to make my build in soundcard (Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60)) to work in 5.1 mode and be able to control rear center and front speaker seperately. I ve done this with this config

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

pcm.softvol {
    type softvol
    slave.pcm    "ch51dup"
    control {
        name    "SoftMaster"
        card    0
    }
}

pcm.ch51dup {
    type route
    slave {
        pcm         duplex
        channels     6
    }
    ttable.0.0 1
    ttable.1.1 1
    ttable.0.2 1
    ttable.1.3 1
    ttable.0.4 0.5
    ttable.1.4 0.5
    ttable.0.5 0.5
    ttable.1.5 0.5
}

pcm.duplex {
    type asym
    playback.pcm    "demixer"
    capture.pcm    "routein"
}

pcm.demixer {
    type dmix
    ipc_key 1028    
    slave {
        channels     6
        pcm         "hw:0,1"
        period_time    0
        buffer_time    0
        period_size    1024    
        buffer_size    4096    #8192    
        rate        48000
    }
    bindings {
        0 0
        1 1
        2 2
        3 3
        4 4
        5 5
    }
}

pcm.routein {
    type route
    slave {
        pcm    "sdsnoop"
        format    S16_LE
    }
    ttable {
        0 {0 0.5}
        1 {0 0.5}
    }
}

pcm.sdsnoop {
    type dsnoop
    ipc_key 1133
    slave {
        pcm        "hw:0,1"
        period_size    256
        periods        16
        buffer_size    16384
    }
    bindings {
        0 0
    }
}

pcm.dsp0 {
    type plug
        slave.pcm    "softvol"
}

pcm.dsp {
    type plug
    slave.pcm    "softvol"
}

ctl.demixer {
       type hw
       card 0
}

I can also play Quake3 and listen to music in the same time. But i cannot use skype and it seems i cannot have any input from mic.
I need to have mpd working also.

I tried to use jack but no luck.

Any ideas ??????

PLZ HELP

Re: via_82xx + 5.1 + Skype +mpd

hi man,
i have created a ~/.asoundrc with this line

pcm.!default {
type plug
slave.pcm "surround51"
slave.channels 6
route_policy duplicate
}

and i thinik it works, except a problem in kde
Sound server informational message:
Error while initializing the sound driver:
Unable to set interleaved!
The sound server will continue, using the null output device.

but i think is that kde don't know to use the file created and make errors at startx.

after this, my real problem is with the 3 plug line-out.
i have an onboard audio card with 3 plug: line-in line-out and mic.
as i have cabled the 3 line-out of my audio5.1 kit i listen sound only with sub and 3 speaker, i don't listen sound by the 2 rear speaker right and left because i think their respective plug that exit by the sub is on the mic or line-in plug on my mobo.
probably i don't have switched the plugs, what do u think?

i don't have changed anything except the creation of the asoundrc file.

finally: it could be nice managing the speaker separately front and rear.
overrighting my asoundrc with yours i will enable to do this?

edit: onboard i have an audio ac97 interface for the frontal panel with an aud-out and a mic.
don't u know how to use this frontal interfaces?
from me, actually the aud-out works and mic seems not work so good. is unuseless now the mic of the frontal panel.
