Summary:                    spdif hw entry fails to work in multi
Description: 
After bug 0000505 was fixed, hw:0,0 only plays to analog devices, and
hw:0,4 to spdif. As one needs output in both, I tried to use .asoundrc ,
and therefore needed to use the "multi" pcm type in order to unite these
two (and then route). This is what I put in .asoundrc

pcm.whole {
    type multi
    slaves.a.pcm "hw:0,0"
    slaves.a.channels 2
    slaves.b.pcm "hw:0,4"
    slaves.b.channels 2
    bindings.0.slave a
    bindings.0.channel 0
    bindings.1.slave a
    bindings.1.channel 1
    bindings.2.slave b
    bindings.2.channel 0
    bindings.3.slave b
    bindings.3.channel 1
}

pcm.rt {
    type route
    slave.pcm "whole"
    ttable.0.0 1
    ttable.1.1 1
    ttable.0.2 1
    ttable.1.3 1
}

The ttable may be wrong - I could not find a sane description anywhere -
but I tried many variants, and besides, playing to "whole" bypasses this.

So here's what I get when playing to "rt" OR to "whole" via alsaplayer :

$ alsaplayer -d whole test.wav

failed to configure output device...trying OSS

then alsaplayer hangs until interrupted.

When I comment out everything related to slave b, "whole" seems to work
(without spdif output, of course). So this seems like a bug in the spdif
device.

Use this:

pcm.rt {
    type route
    slave.pcm whole
    slave.channels 4
    ttable.0.0 1
    ttable.1.1 1
    ttable.0.2 1
    ttable.1.3 1
}

and run with -d rt .
