[Discuss-gnuradio] Problem to listen to FM

[jingx kwan]

Hello,

It isn't create any sound from the usrp_wfm_rcv.py command when I set to listen to the Frequency 91.5. It is running under Ubuntus 8.04 and Dell Latitude D610 notebook. I doubt that the notebook sound card doesn't support the below command line. I don't know why I can't listen to the FM. Could you please point me to the solution? 
 

I run the following command:

./usrp_wfm_rcv.py -f 91.5M -O plughw:0,0

Thank you.
