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

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

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.
