[Discuss-gnuradio] Strange behaviour of QT Sink on gnuradio-next on Mac

[Albert Chun-Chieh Huang]

Hi, all,

I'm not sure if it's related to gnuradio-next or gnuradio-next on Mac.

I've built gnuradio-next from MacPorts by the following command:
$ sudo port install gnuradio-next +full configure.compiler=llvm-gcc-4.2

It was built successfully. When I try to create a flowgraph to generate
DTMF tones and monitor them on QT GUI Sink, I found their frequencies
are divided by 2. The flow graph is here:

By the same installation procedure, QT GUI Sink on gnuradio 3.6.4 works
fine with these DTMF tones. Right now I switched back to gnuradio 3.6.4
to continue.
