Lots of "S" in output

Hi,

Hardware: USRP2, Tuner Card

I am trying to run a FM receiver to receiver a FM station on my right
speaker and another on my left speaker.
Im able to do this successfully.

However when I integrate this function into a GUI interface to display
the
fft being received, my FM audio has lots of jitter and the output looks
like:
*
Launching a SCIM daemon with Socket FrontEnd…
Loading simple Config module …
Creating backend …
Loading socket FrontEnd module …
Starting SCIM as daemon …
GTK Panel of SCIM 1.4.7

Using RX d’board 0x0003

gr_fir_ccc: using SSE
gr_fir_fff: using SSE
aUaUaUaUaUaUSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS

The aUaU is not a big concern, it only arises once a few seconds due to
small difference in audio freq. However the SSS comes up continuously
and I
can’t find what it means.

Any suggestions are welcome, Thanks.

My blocks are connected as such,

self.connect(self.u, head_left)
self.connect(self.u, head_right)
self.connect(tail_left, (audio_sink, 0))
self.connect(tail_right, (audio_sink, 1))

There is a pipeline which connect head to tail, which takes care of

getting the two different frequency channels

self.connect (self.u, self.src_fft)

This is done inside the def build_gui

Thanks,
