Solved pluggable usb headset

[mro]

how do I get a pluggable USB headset (Razer Kraken V3 X RZ04-03750100-R3M1) working with a FreeBSD 13.2 Lenovo X250 Thinkpad?

I guess I have to tell devd how to connect, but how do I do that?

Just plug it in.

snd_uaudio(4)

I guess I haven't set up audio properly, as I have to manually switch to the headset via

$ sysctl hw.snd.default_unit=3

Will hunt for virtual oss and see.

I ended up with

$ cat /usr/local/etc/devd/usb-headset.conf
attach 100 {
    match "device-name"        "pcm3";
    action "sysctl hw.snd.default_unit=3";
};
