I'm able to reproduce the problem. It looks like the device enumeration is probably not implemented. If so, there are just few lines missing from the sndio backend, they are supposed to return the device "list" (a single SIO_DEVANY entry). After a quick look at the sources, it's not obvious how register a "device provider" to expose the device.
