USB Audio Devices

Recently, I got a new SteelSeries Pro headset with a USB DAC. My motherboard also has an onboard sound card and my NVIDIA GPU does as well. Yet, I could only see the realtek audio from my motherboard in the xfce4-mixer application.

In order to select the input for some apps on MidnightBSD, you must first change the default audio device.

cat /dev/sndstat

This gives you a list of all the audio devices on the system. Figure out which device you'd like to use and then run

sysctl hw.snd.default_unit=7

where 7 is the device in the 7th position in the list in my case. Yours will vary.

Then restart your xfce-mixer and you will find the device listed is now your device. You can playback from firefox or whatever app you're trying to use.
