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: https://vis.nu/blog/digigram_vx222e_isn_t_seen_in_arch_linux

Any pointers would be helpful. Thanks!
