umik-1 seems to work perfectly in Ubuntu 16.04. The only thing you need to be careful about (and this isn't much!) is to plug it into a USB 2.0 port.

If you plug it into a 1.0 port, the blue light on the mic will light up, but the device won't be recognised. In lsusb the device is listed, but there is no descriptor. Pulse recognises the device immediately. In arecord -l it comes up as:
card 1: U18dB [Umik-1  Gain: 18dB], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

in arecord -L:
sysdefault:CARD=U18dB
    Umik-1  Gain: 18dB, USB Audio
    Default Audio Device
front:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    Front speakers
surround21:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    2.1 Surround output to Front and Subwoofer speakers
surround40:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    4.0 Surround output to Front and Rear speakers
surround41:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
iec958:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    IEC958 (S/PDIF) Digital Audio Output
dmix:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    Direct sample mixing device
dsnoop:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    Direct sample snooping device
hw:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    Direct hardware device without any conversions
plughw:CARD=U18dB,DEV=0
    Umik-1  Gain: 18dB, USB Audio
    Hardware device with all software conversions

In pulse, there are two devices listed. It's unclear if they represent different ways of using the device. One is listed as "Digital Input (S/PDIF)" under Umik-1. The other is just listed as "Microphone" also with Umik-1.

Hi,
Default arecord also stalls for me, but this works:
arecord -f S24_3LE -r 48000 -c 2 -D hw:2,0 -d 5 test.wav
