The device would not work when the receiver was plugged into a powered USB hub, but it works perfectly when the receiver is connected directly to the pc's usb ports. I'm very pleased with ease of use and quality of sound.

Test with:
arecord -D plughw:CARD=Microphone -f S24_3LE -r 48000 -c 1 -d 20 lark.wav

The device samples at 48KHz. I use it with Whisper which requires 16KHz
so I created a virtual device using ALSA plug plugin using this entry in /etc/asound.conf

pcm.lark16 {
type plug
slave.pcm "hw:Microphone,0"
}

This allows transparent conversions of sample rate, channel count and bit-depth formats.

Test with:
arecord -D plughw:CARD=Microphone -f S16_LE -r 16000 -c 1 -d 5 test.wav
