Attention all newbies:
Please read the GNU Radio FAQ and the USRP FAQ and try searching with
google before posting to the list.
Most commands support a --help option. Try using it.
Also read the README files contained in the source code.
After doing all of the above, if you’ve still got a question, you’re
more likely to get a helpful response on this mailing list if you
provide us information that could allow us to help you. E.g., what
version of GNU Radio are you using; what OS/distribution/version are
you using; what (specific) kind of computer are you running GR on; if
you’re using a USRP, what daugherboard(s) are you using; the exact
command line you used. Also, please remember that no one here gets
paid to answer your questions. Questions that demonstrate that
you’ve done your homework are more likely to elicit a response.
FYI, “FYI” stands for “for your information”. It’s neither an error
nor a warning. It’s just information.
Most commands support a --help option. Try using it.

May be we need to write a special wiki page with a link from the main
gnuradio wiki for the newbies like (’ New to GnuRadio Click Here’, or
‘For Newbies – Start From Here’).

audio_alsa_sink[hw:0,0]: unable to support sampling rate 32000
card requested 44100 instead.
This means the your audio_card does not support 32000 Hz samplerate.
So you get Audio Underruns (aU)
This can be solved by using the commandline parameter
-O plughw:0,0
This will use the alsa software resampler to resample the 32000 to
44100
Please use reply-to-all when using the mailinglist.
Now I was the only one who got your reply, and not the mailinglist.
