It should work just by typing, and you can always copy and paste

"cat /proc/asound/card0/codec#0 > ~/Desktop/codec_dump.txt"

and changing the "codec#0" part as needed like "codec#1"

"cat /proc/asound/card0/codec#1 > ~/Desktop/codec_dump.txt"

just keep going up in numbers, I just tried on a EP31 motherboard
I had to up go to "codec#2" like this

"cat /proc/asound/card0/codec#2 > ~/Desktop/codec_dump.txt"

You might have to delete the empty TXT files after an unsuccessful
attempt, maybe some how there not being overwritten buy the new
file each time

I am going to try a PC with non Realtek sound next, but it should work
the same way
