The current position update is not precise enough for PulseAudio to work reliably with the timer-based scheduling on Baytrail, Cherrytrail, Broadwell.
Disable the NO_PERIOD_WAKEUP capability and use BATCH to signal that the position is only reliable and updated during period_elapsed events.
This will be reverted when the firmware provides a more accurate position for those platforms.
