Troubleshooting • RME HDSP PCIe and RPi 5

I have connected a RME HDSP PCIe card through a PCIe adapter and the Pimoroni NVMe Base. I have built the ALSA hdsp kernel module. When I load it with 'sudo insmod hdsp.ko' I get the following error.

[ 330.825112] hdsp: loading out-of-tree module taints kernel.
[ 330.825886] hdsp 0000:01:00.0: enabling device (0000 -> 0002)
[ 330.826138] hdsp 0000:01:00.0: RME Hammerfall DSP: no buffers available
[ 330.826149] hdsp: probe of 0000:01:00.0 failed with error -12

I have traced the error to the call snd_devm_alloc_pages(&pci->dev, SNDRV_DMA_TYPE_DEV, size);

Any ideas what I am missing?
