[alsa-devel] Digigram VX222e not seen as card

[Sam Mulvey]

A radio station I'm working on has a machine with a Digigram VX222e
connected to it.

According to the Digigram site and the ALSA website, the sound card is
supported by ALSA. Unfortunately, it doesn't appear to be detected as a
sound card. Reading online, it requires some firmware, but it appears
that my system has the proper firmware installed.

The VX222e is a PCIe card, but it appears to be PCI on the card with a
PCIe to PCI bridge. According to Digigram's support site, they made a
hardware change in March of 2017, and I suspect that this might be the
problem.

I'm guessing it might be as simple enough as an ID match that I need to
add to a module, but I've never worked with the card before, and I'm a
little stuck.

There's nothing regarding the card in dmesg, but it is visible in lspci:

I'm also documenting what I've got and what I've tried here:

Any pointers would be helpful.   Thanks!
