Ok everything works well after adding the right firmware to
/lib/firmware/hdsploader! I'am very happy and thank's to the folks
pointing me in the right direction!
Cheers!

Adding dtoverlay=pcie-32bit-dma too /boot/firmware/config.txt is
helping a lot! The card is recognized in alsa! But yet no controls but
says it wants to update firmware! I can feel I am close!

Who is responsible for this? We must have a talk! (:

From what I can tell comparing to a working system is that I have
all needed kernel modules loaded. the oss are indeed no longer
needed. Thank's for pointing me out.
Here a paste bin with the info I could gather.
https://pastebin.com/dAfDDnkM
The missing interrupt I wonder about and still the no available
buffer error which returns -12 but also the memory address is stated
beeing [virtual] on the PI. Is there something wrong with the bus
not beeing PCI standard compliant?
What my intuition tells me is that the PI is handling the DMA of the
PCI bus in a different way than other architecture. I am not sure
what to do as to troubleshoot further /: Read code?
Thank's

Are you sure those are current? "oss" usually refers to the
open-source-sound that predated ALSA around 25 years ago.
The modinfo description from kernel 5.10.0 for snd-pcm-oss
seems to indicate it's for OSS emulation: "PCM OSS emulation
for ALSA." For kernel 5.10.0-29-amd64 from Devuan Chimaera,
snd-seq-oss is not even listed.
