USB microphones with FreeBSD-CURRENT

[Mathias Picker]

Hi Graham,

which application tries to use the mic? I sometimes had problems 
with gotomeeting, but other than that everything works.

Is the microphone recognized at a testing site like 
https://www.podcastinsights.com/online-mic-test/ ?

I just tested with it & my jabra 310 and it works fine. Actually, 
firefox asks which recording source should be used.,
hw.snd.default_unit just preselects a source.

My system

% uname -a
FreeBSD Danton 12.1-STABLE FreeBSD 12.1-STABLE r356939 GENERIC 
amd64


% cat /dev/sndstat
