At work I’ve been using several different USB headsets. Let’s see if they work on FreeBSD.

Microsoft LX-6000

Relevant dmesg output after plugging it in:

Jabra EVOLVE 20 MS

On the back of the volume control unit, it says MODEL: HSC016.

For both headsets

Checking installed devices

> cat /dev/sndstat
Installed devices:
pcm0: <Realtek ALC887 (Rear Analog)> (play/rec)
pcm1: <Realtek ALC887 (Front Analog)> (play/rec) default
pcm2: <Realtek ALC887 (Internal Digital)> (play)
pcm3: <USB audio> (play/rec)
No devices installed from userspace.

Switch to the headset.

> sysctl hw.snd.default_unit=3

Switching back.

> sysctl hw.snd.default_unit=1

Audio quality (both listening and recording) is adequate for both.

Recording audio from the headsets

Using ffmpeg.

> ffmpeg -thread_queue_size 1024 -f oss -i /dev/dsp3.0 test.m4a
