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?
<br>
<br>
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?

The modinfo description from kernel 5.10.0 for snd-pcm-oss

seems to indicate it's for OSS emulation: "PCM OSS emulation

snd-seq-oss is not even listed.
