The microphones are working correctly on other clients with Teams (HDX redirected) and if I connect a headset like Jabra Evolve 75 that microphone works correctly so it's not a general issue in the environment or the client but it's specifically that Teams HDX does not work with this microphone. It displays correctly as a device in Teams but no sound goes through.

Also if I in the Citrix session go to Start > Settings > System > Sound, I can see the soundbar "move" when I speak so the citrix session obviously picks up the microphone and inside the Windows session it works. So it's just for the Teams redirection the microphone isn't working.
1. option snd_hda_intel.dmic_detect=0 has actually deprecated. I then used snd_intel_dspcfg.dsp_driver=1 instead.
Now the system is properly forced to use the legacy snd_hda_intel module.
Under this case, the behavior of cat /proc/asound/cards, aplay -l, aplay -L, speaker-test -c 2 remained as mentioned above and corresonding dmesgs are
2. snd_intel_dspcfg.dsp_driver=0 to use the modern sof-audio-pci-intel-tgl
This time cat /proc/asound/cards yields "no soundcard" and corresponding dmesgs are
By reverting to default configs (i.e. letting sof-audio-pci-intel-tgl take over) my system cannot even detect the soundcard (as mentioned, cat /proc/asound/cards yields nothing). If I add some kernel parameters and let the legacy snd-hda-intel take over, at least the card is detected (but still no sound).
Have you ever wondered what it would sound like to listen through sixteen ears? This past March, hundreds of Central Illinois children and families experienced microphone-array augmented listening technology firsthand at the annual Engineering Open House (EOH) sponsored by the University of Illinois College of Engineering. At the event, which attracts thousands of elementary-, middle-, and high-school students and local community members, visitors learned about technologies for enhancing human and machine listening.
The oldest and most intuitive listening technology is the ear horn, pictured above. This horn literally funnels sound waves from the direction in which it is pointed. The effect is surprisingly strong, and there is a noticeable difference in the acoustics of the two horns we had on display. The shape of the horn affects both its directional pattern and its effect on different sound wavelengths, which humans perceive as pitch. The toy listening dish shown below operates on the same principle, but also includes an electronic amplifier. The funnels work much better for directional listening, but the spy gadget is the clear winner for style.
These mechanical hearing aids rely on physical acoustics to isolate sound from one direction. To listen in a different direction, the user needs to physically turn them in that direction. Modern directional listening technology uses microphone arrays, which are groups of microphones spread apart from each other in space. We can use signal processing to compare and combine the signals recorded by the microphones to tell what direction a sound came from or to listen in a certain direction. We can change the direction using software, without physically moving the microphones. With sophisticated array signal processing, we can even listen in multiple directions at once, and can compensate for reflections and echoes in the room.
Our research team is studying ways to apply array processing, like the technology in the Echo and other smart speakers, to improve listening devices such as hearing aids. By listening through dozens or hundreds of microphones instead of just two ears, humans could hear better in crowded, noisy places.
