Using a USB headset on FreeBSD
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:
ugen0.6: <Microsoft Microsoft LifeChat LX-6000> at usbus0 uhid0 on uhub0 uhid0: <Microsoft Microsoft LifeChat LX-6000, class 0/0, rev 2.00/2.12, addr 15> on usbus0 uaudio0 on uhub0 uaudio0: <Microsoft Microsoft LifeChat LX-6000, class 0/0, rev 2.00/2.12, addr 15> on usbus0 uaudio0: Play[0]: 44100 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record[0]: 44100 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: No MIDI sequencer. pcm3: <USB audio> on uaudio0 uaudio0: HID volume keys found.
Jabra EVOLVE 20 MS
On the back of the volume control unit, it says MODEL: HSC016.
Relevant dmesg output after plugging it in:
ugen0.5: <GN Netcom A/S Jabra EVOLVE 20 MS> at usbus0 uhid0 on uhub0 uhid0: <GN Netcom A/S Jabra EVOLVE 20 MS, class 0/0, rev 2.00/4.01, addr 43> on usbus0 uaudio0 on uhub0 uaudio0: <GN Netcom A/S Jabra EVOLVE 20 MS, class 0/0, rev 2.00/4.01, addr 43> on usbus0 uaudio0: Play[0]: 48000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play[0]: 44100 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play[0]: 32000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play[0]: 16000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play[0]: 8000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record[0]: 48000 Hz, 1 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record[0]: 44100 Hz, 1 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record[0]: 16000 Hz, 1 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record[0]: 8000 Hz, 1 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: No MIDI sequencer. pcm3: <USB audio> on uaudio0 uaudio0: HID volume keys found.
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
