Yes, it's known that some (many?) HD-audio hardwares have bugs regarding the DMA position inquiry. They don't update the DMA positon properly and/or give inaccurate positions. The driver passes the value as hardware gives, and this seems to fool some apps (e.g. JACK). I'll try to implement some workaround in the driver, at least, not to return the wrong position in near future.
