so everything was running without errors. well not so fast. i turned the computer off (so i could get closer to a tower) and now one of the old errors is killing Op25 again:

Imported legacy fsk4
Using Volk machine: ssse3_32
Traceback (most recent call last):
File "/home/matt/op25_grc.py", line 523, in
tb = op25_grc()

return getattr(self._hb, name)
AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'

disconcerting to see this error again but by disabling the 'FFT Sink", i can get rid of that error. the scope plot runs but i have no sound. there is some output in terminal:

first: any idea as to how i can get some sound? what should i be looking for in the scope?

second: i have a strong desire to get rid of the "AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'" without disabling the fft sinks! how is that i was not getting this error with the fft sinks enabled after uninstalling and reinstalling OP25 but after turning the computer off and restarting the error is back?

third: what is this "memory leak" message?

thanks.
