Thank you, for your respond "ptn".
For the commands:
aplay -l; cat /proc/asound/cards; cat /proc/asound/pcm; arecord --list-devices; cat /proc/asound/card0/codec#* | grep Codec;,

     THE OUTPUT IS IDENTICAL TO YOUR FILES(DATA).

For the commands:
lspci -vv; lshw; lspci -nv; gmesd; and others, I'll do next few days.
