Yes, if you provide a little more information:

Have you read all the READMEs, FAQs and things labeled with "doc" or 
"documentation"?
Have searched the mailing list archives? I recommend GMANE.org.
Have searched the Internet?

If you'r unsure what to do first and what to write in a mail asking for 
help, have a look at
http://www.catb.org/~esr/faqs/smart-questions.html

You've told us about your computer model and your OS version, but not 
about your GNU Radio version.
Did you install it through your OS' packet managment system or build 
from source viw SVN? Which version?

Have you tried other commands? Did they work? Some output on the command 
line?

Have you been able to get some sound output with the programs from 
gnuradio-examples/python/audio directory? If dial_tone.py is not 
working, you should sort this out at first.

"It isn't create any sound" is not very specific.
Please send us the copy of the output of the command. If there are 
errors, you have not showed us any trace of it.
