Then if your question is actually "which is the default card", the answer is : card1 !
BTW, pay attention, the file you wanted to list is actually /etc/asound.conf
And... you also want to confirm that it does not get its functionally equivalent in your home directory named .asoundrc
But maybe your question is why is card1 your default sound card ? _________________

Yes, i want to know why card1 is my default card.
# ls -l /root/.asoundrc
ls: /root/.asoundrc: No such file or directory
and also i do not modify alsa.conf file.
