When I am listing devices with sound device, I am missing my Desk Digital Audio microphone, it only shows output (0in, 2out)!

user@ubuntu:~$ python -m sounddevice
  0 HDA Intel PCH: HDMI 0 (hw:0,3), ALSA (0 in, 8 out)
  1 HDA Intel PCH: HDMI 1 (hw:0,7), ALSA (0 in, 2 out)
  2 HDA Intel PCH: HDMI 2 (hw:0,8), ALSA (0 in, 8 out)
  3 HDA Intel PCH: HDMI 3 (hw:0,9), ALSA (0 in, 8 out)
  4 HDA Intel PCH: HDMI 4 (hw:0,10), ALSA (0 in, 8 out)
  5 Desk Digital Audio: USB Audio (hw:1,0), ALSA (0 in, 2 out)
  6 hdmi, ALSA (0 in, 8 out)
  7 pulse, ALSA (32 in, 32 out)
* 8 default, ALSA (32 in, 32 out)

With aplay and arecord my desk digital audio have both speaker and microphone, and inside ubuntu sound settings it works fine with both speaker and microphone.

How to troubleshoot the missing device?

The information about input and output channels comes from the PortAudio library.

Maybe you can try the latest version, v19.7 should be available.

If there is no package, you can try to compile it from source.

If this doesn't help, you should ask the PortAudio people: http://portaudio.com/contacts.html

Same sounddevice.query_devices (microphone) missing issues as @peder82. I've tried the latest PortAudio version (v19.7), no success.
