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
