Re: <https://forums.freebsd.org/posts/560927> it may be that the port to FreeBSD does not yet benefit from patches that were up-streamed in January 2021.
Long been on my list since I have to hot-plug some audio devices and the stuff that Greg V upstreamed may work, but limited cycles are a hamper. Anyone is welcome to hack at the port itself in the meantime.
Awsome :-) Hotplug would be a great feature for my Bluetooth headset attached/detached on the fly! So far I had to kill PA daemon by hand :-)
One last thing missing would be to have Bluetooth and Hotplug/Devd react on Bluetooth connections, starting virtual_oss, then reloading PulseAudio.. and FreeBSD will be fully featured multimedia station! :-)
