Can't interrupt. rx_fm doesn't stop when sent SIGINT

added version include for setupStream check

On debian 11 (VM intel 64) when I press [ctrl]+C rx_fm prints "^CSignal caught, exiting!" but doesn't actually exit. I have to open another terminal to send it a SIGKILL to stop the process.

marc@debian:~$ rx_fm -M wbfm -f 96.8M | play -r 32k

Same commit of rx_tools on Raspbian GNU/Linux 10 on a RaspberryPi 3B+ exhibits the same behaviour.

Update. I didn't provide the correct device (1,driver=remote (remote SDRPlay)).

But still the same issue with SIGINT:

marc@debian:~/src/rx_tools$ rx_fm -d 1,driver=remote -a A -M wbfm -f 96.8M | play -r 32k -t raw -e s -b 16 -c 1 -V1 -
