Yeah I was more thinking built on BeOS with the pci v1.1 header but

No it's a multi audio one, it produces some recognizable noise in QEMU, 
but it's quite awful and I don't know if it's caused by my machine 
being too slow or the mixer being too cpu intensive or the driver being 

I think I have an es137x somewhere, I could try it on real hw if it 

The R3 support node shoud be mostly complete btw, but noone stepped 
forward to finish it.
