This happens with HDSP cards. RME has a page on it.
Their story is that some of the older HDSP cards require a voltage level
that the PSU fails to provide during booting, and if that happens, the card
is never visible to the BIOS. They have a h/w hack to work around it, but I
think their recommendation is to get a better PSU.
However ... this has happened to me with an HDSP card in a machine in which
it had worked for years. I did a kernel upgrade, and after the reboot, the
HDSP card was never seen again. I installed it in 3 other machines, and it
was not visible there either. This happened years ago (perhaps 4?) and I
never got the card working again; I also moved onto computing hardware with
no physical space for a PCI card like this.

Hi folks, I have a problem - I'm mounting an
exhibition and trying to
install hdsp card with a multiface card. The machine I've been given and
the only one available here has one PCI slot and several other more modern
types. I've installed alsa-firmware and alsa-tools from source, bu the
problem is that the card is not showing up with lspci and aplay -l, nor is
it showing up cat /proc/asound/cards
Any suggestions please? I've looked in the BIOS and the slot is enabled.
There are no other PCI type cards installed.
Thank you,
Iain
