The real issue here is the sound card in your machine doesn't support
the 32000 sampling rate.  However, the ALSA driver has an internal
resampler, so you can run:

$ usrp_nbfm_rcv.py [other options] -O plughw:0,0

The -O parameter tells the ALSA driver which hardware device to use,
and 'plughw' is the name of the resampler.

If that works, then you can make this the default, but setting it in a
GNU Radio configuration file.

Edit ~/.gnuradio/config.conf (create it if necessary), and add or edit
the following section:

[audio_alsa]
default_output_device = plughw:0,0
