I'm basically using the same code as for the tsadc, just added in a fourth channel, and none of the setup calls are returning errors, but the first iio_buffer_refill() call returns an error. I've dumped out the parameter that is being passed to the iio_buffer_refill() call and it is the same as the value that was returned from the iio_device_create_buffer() call.

I believe that you need to register an interrupt for buffered access to work.
Do you have an interrupt connected and registered?
