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?

[root@localhost gnuradio-3.1.3]#
Using RX d'board B: TV Rx Rev 3
audio_alsa_sink[hw:0,0]: unable to support sampling rate 32000
  card requested 48000 instead.

Also, what is this?  I see it on some apps and not others.  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.

please read

aU means "audio underrun", which means the soundcard was waiting for
data and did not receive any..

concerning the sampling rate and, try running it with
the -O plughw:0,0 option... tell me if this fixed it...
