I am getting the following: It seems that my sound card wants higher sampling rate From previous post it seems that should not be an issue. But the sound from my FM is broken. Is there a way to fix it?

It appears to be a feature of python's raw_input() except that it only happens while the alsa audio stuff is loaded. I couldn't figure it out and imagined it was peculiar to my platform. -- If riding in an airplane is flying, then riding in a boat is swimming. 107 jumps, 43.5 minutes of freefall, 83.4 freefall miles.

please read http://gnuradio.org/trac/wiki/UsrpFAQ/Gen#OUuainoutput aU means "audio underrun", which means the soundcard was waiting for data and did not receive any.. concerning the sampling rate and usrp_wfm_rcv.py, try running it with the -O plughw:0,0 option... tell me if this fixed it...
