Sorry you haven't gotten more replies. One of the great ways to learn linux is to run into problems like this, then do some searching and troubleshooting to figure it out. Google is your friend, and googling a phrase from your error output can give you lots of links. Add your distribution if you want to narrow it down. For example, I just googled:
ubuntu ALSA lib confmisc.c:768: (parse_card) cannot find card '0'
and got 1860 entries:

LQ can be a great resource, but many folks get fatigued from trying to help people who don't seem to want to help themselves. Your OP request to "describe rather step by step" may have inadvertently put up red flags, and your FU probably sealed the deal! ;-)
I don't know what you do or don't know, so I'll assume nothing. ALSA refers to the sound modules and libraries, and what the messages are saying is that the program can't find your sound card. Next questions I might ask:
1. What happens if you run civclient as root?
2. Can the regular user successfully run other sound applications?
Good luck!
