thank you for your work!

this port as well as it's dependencies you provided previously (gr-osmosdr 
soapy-hackrf soapy-rtlsdr soapysdr) compile just fine on my amd64 7.9 desktop.

I tried to use it with a HackRF One (firmware 2024.02.1) but the audio output 
is garbled when trying to demodulate radio stations.

the output looks thusly:

gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.10.11.0
built-in source types: file rtl rtl_tcp hackrf rfspace soapy redpitaya

also tried to plug in a SDRplay RSPdx, but there is no surprise that the 
user-space driver for it is missing (since it's closed source [1]). maybe it 
should not be mentioned in gr-osmosdr/pkg/DESCR?

both devices work flawlessly in Gentoo. HackRF One has an audio problem in 
FreeBSD as well (audio chunks are played correctly but with an overlap).
