288 depends on SND_HDA_INTEL
290 Say Y to enable HD-Audio Keep Alive (KAE) aka Silent Stream
291 for HDMI on hardware that supports the feature.
293 When enabled, the HDMI/DisplayPort codec will continue to provide
294 a continuous clock and a valid but silent data stream to
295 any connected external receiver. This allows to avoid gaps
296 at start of playback. Many receivers require multiple seconds
297 to start playing audio after the clock has been stopped.
298 This feature can impact power consumption as resources
299 are kept reserved both at transmitter and receiver.
