USB microphones with FreeBSD-CURRENT

[Mathias Picker]

Hi Graham,

firefox uses pulseaudio by default, so you might try to tweak 
pulseaudios source.
Set the default with pacmd set-default-source [index] (find the 
index via pacmd list-sources)
and check/rewire audio streams with pavucontrol[-qt]

Good luck,

Mathias
