But what I am really wondering is how to set buffers in alsa config and
how to have access to the "disconnect" option and leave the unit in
standalone mode. Any ideas?

Hey there!
Ok so interface is composed of 52pi PCIe slot and a PCIe to PCI riser.
When connected a digiface the unit is powered from the PI. For now
there is no converters plugged-in.
With a multiface I've run into power supply issues even with external
supply. Tried both powering the unit itself or through the PCI riser.
Steps to reproduce on RPI5 bookworm:
1. Compile kernel with PCI soundcard support.
2. install alsa-utils, alsa-tools, alsa-tools-gui and
alsa-firmware-loaders
3. Download and copy firmwares from hdsploader to
/lib/firmware/hdsploader/ (create directory). Not sure why they
were missing. Maybe optional to update the firmware.
4. add dtparam=pciex1 dtparam=pciex1_gen=2 (maybe not necessary) and
dtoverlay=pcie-32bit-dma to /boot/firmware
/config.txt
5. Check output of hdsploader and let me know if something's missing!
6. Have fun!

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!
Oh by the way, what type and model of PCI extender are you using for the Pi5?
