I caught notes about this update while skimming the repo the other day. I'm excited to take this for a spin. I'll be testing on the Delaware State 800 system. That system currently runs a SmartZone control channel with P25 CAI audio. I've been waiting for them to finish their upgrade to a true P25 system so I could move forward with another project, but now this feature update beats them to it. I'm happy to provide feedback when I get the new version running and configured here.
Regarding the question on running OP25 via WSL, would using rtl_tcp get around the need for WSL to support USB? (I'm not sure what WSL's support for audio might be, as I haven't had a chance to try it out myself yet.) I don't have a need to run within WSL here, but I nearly exclusively use rtl_tcp as my source with my current OP25 install, so that thought came to mind.
