[ubuntu-studio-users] Support for Digigram PCX822np on Ubuntu Studio 20.04 LTS

[Andrew]

Hi, I have a digigram pcx822np card I am trying to use with Ubuntu 
Studio on 20.04 lts

According to digigram, this card is supported by alsa in the kernel, so 
I would expect lsmod to show something related to this.
lspci shows:-
04:00.0 Multimedia audio controller: PLX Technology, Inc. PCI9080 
32-bit; 33MHz PCI <-> IOBus Bridge
as well as the onboard Intel NM10/ICH7 Family High Definition Audio 
Controller.

I'm not seeing it in the sound cards either:-
# cat /proc/asound/cards
  0 [Intel          ]: HDA-Intel - HDA Intel
                       HDA Intel at 0xd0600000 irq 35

So I believe the required module is not loaded. Google doesn't throw up 
much help regarding a suitable module or links to source code. Github 
lists Digigram-audio as a repo, but the README doesn't mention my card. 
However, the source code does refer to pcxhr cards, which may support 
mine.

I'm patched up to date.

What would the advice be to proceed with this please?

Regards,
Andrew
