Could I have help setting up boatbod for DMR (non-trunked) reception and decoding? Nothing appears in the terminal window after starting except "Allocating 15 zero-copy buffers". There is no audio,
Raspberry Pi 4, Bookworm, XFCE, updated
I am using the gr3.10 branch. I have p25 trunking working well on this Pi4.
I am apparently receiving signal. It shows in Spectrum and 4 lines in symbol. Pressing 2 shows no plot.
I keep seeing "Allocating 15 zero-copy buffers" in the terminal when I activate plots.
