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:
- Compile kernel with PCI soundcard support.
- install alsa-utils, alsa-tools, alsa-tools-gui and alsa-firmware-loaders
- Download and copy firmwares from hdsploader to /lib/firmware/hdsploader/ (create directory). Not sure why they were missing. Maybe optional to update the firmware.
- add dtparam=pciex1 dtparam=pciex1_gen=2 (maybe not necessary) and dtoverlay=pcie-32bit-dma to /boot/firmware
/config.txt- Check output of hdsploader and let me know if something's missing!
- Have fun!

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? _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
