Hello all,I have some problems with GNURadio and my USRP board when I use the
usrp_wfm_rcv demo application. I have the error below:audio_alsa_sink[hw:0,0]:
unable to support sampling rate 32000
card requested 44100 instead.
audio_alsa_sink[hw:0,0]: set_period_time_near failed: Argument invalide

I have tested the mono_tone application with success and I can listen the
tone.I have checked that my sound card is not in use by some other
application.Do you have any idea ?
Thanks in advance.Patrick
