Hi Rob, This BSD code does WaveRT, no idea if it handles polled mode. http://code.google.com/p/cmediadrivers/
Thanks Jerry, but it was not the driver code I was after, instead some direct kernel streaming client code which handles the WaveRT polled mode. But further to my case, I've checked the periodicity of the thread and it does seem that with 5 ms I get to handle pretty much exactly 220 frames per iteration (which is pretty stable), but still I get the pops/clicks. Question then is how I should relate to the mapped play position register. The HW fifo size is reported to be 32 bytes, with codec/chipset delay 400 ns (rather tiny value?)
