Sampling rate mismatch in Fedora Core 5

GNU Radio
1

Hi,
After a long wait I recieved the hardware. I was trying to run FM
Reciever
but there is some problem related to the sampling rate of my computer. I
received following error message:

[root@utdallas usrp]# ./usrp_wfm_rcv.py
Using RX d’board A: Basic Rx

gr_fir_ccf: using SSE
gr_fir_fff: using SSE
audio_alsa_sink[hw:0,0]: unable to support sampling rate 32000
card requested 44100 instead.

** (python:16205): WARNING **: IPP request failed with status 1030

** (python:16205): WARNING **: IPP request failed with status 1030
FYI: No Powermate or Contour Knob found

The GUI is opening very well, and I can see the frequency spectrum.
After getting this error, I wen to the control centre of Fedora Core 5,
and
changed the default sampling rate to 32000 Hz, but the problem was not
resolved.

Can somebody tell me how to deal with this problem? And, what does the
IPP
Request error tell exactly?

Thank you
Tarun

Copy’n’pasted from the archives:
The solution is to add “-O plughw:0,0” to the end of your command line
(without the quotes), which causes ALSA to resample the output to be
at a compatible sample rate.
