Audio support in Home Assistant OS

Hello everyone!
I have Home Assistant OS installed on a Pi4.

The problem is with audio devices. I bought a usb speakerphone. After complete reboot of the Pi it is recognized and I can select it as output and input device in the Rhasspy Add-on configuration.
Though, in the Rhasspy audio recording and playback settings I don’t see it in the device list.

I know that Rhasspy uses either PyAudio or arecord for audio recording and aplay for audio playback.
Apparently, arecord and aplay are missing in HAOS (I tested with arecord -l and aplay -l commands through terminal). Don’t know about PyAudio, if it is missing or not.

Can you propose solutions to enable audio record and playback in HAOS?
