aU on FM

[Inderaj Bains]

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]#
/usr/local/share/gnuradio/examples/usrp/usrp_wfm_rcvi.py
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
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...

Hi Dmitris

Yes I had identified the aU as my audio card consuming samples too fast (the FAQs were helpful)
And the solution you gave worked fine, I can hear my FM nice and clear, Yay!!!!!

Thanks a lot :)
