My ymf724f does not have spdif, only with ac97 stac9704
Is it feasible to remove playback device 2 (rear) and control (e.g. 4
ch Duplication) by checking sdac bit of ac97 registers to know that it
does not support 4 channels ?
How about device 1 spdif since this card does not have spdif connector ?
what is the difference of capture device 0 and device 3 ?

Yes.

How could this be detected?

The default device can mix lots of sources together; the AC'97 device is
a direct input from the AC'97 codec.

ymf724f does not support I2S Zoom Video Input and my ymf724f sound
card does no have digital input
so the function of capture device 0 and device 1 of my ymf724f are the same
and it seem that they can used for recording concurrently and the
vumeter of two instances of arecord change at the same time
arecord -vv -D hw:0,0 -f cd /dev/null
arecord -vv -D hw:0,3 -f cd /dev/null
Does this mean that it allow two duplex application at the same time
if it can be combined to 2 subdevices
