I've tried to snip and reformat this to make it easier to read. Sorry if it
is garbled but my eyesight isn't good and I found the original as it
arrived hard to follow...

OK.

I don't know the card, so can't be sure. But it may be possible to sort
that out by including a 'format' line in a 'plug' or !default in .asounrc
or elsewhere. For example. if I have
pcm.plug0 {
type plug
slave {
pcm "hw:1"
format S24_3LE
}
}
in my .asoundrc file then I can use -D plug0 to play sounds to my USB DACs
that are 'card 1' but which require the stream to be S24_3LE format.
Putting the same format into !default like
pcm.!default {
type plug
slave {
pcm "hw:1"
channels 2
format S24_3LE
}
}
make this the alsa default with no need to use -D to direct the output.
(The above is stereo so you may also need something like a 'channels 6'
line for 5.1). Can't say if this will help in your case, though. Your card
may not co-operate. And if you also are using other software like Pulse it
may get in the way of such a basic approach when not using aplay.

That will happen if something else is already playing the hardware without
giving an input via dmix or similar, I think.

I just redirect output from a command into a file with '>' or cat things.
