340 Say Y to enable HD-Audio Keep Alive (KAE) aka Silent Stream
341 for HDMI on hardware that supports the feature.
343 When enabled, the HDMI/DisplayPort codec will continue to provide
344 a continuous clock and a valid but silent data stream to
345 any connected external receiver. This allows to avoid gaps
346 at start of playback. Many receivers require multiple seconds
347 to start playing audio after the clock has been stopped.
348 This feature can impact power consumption as resources
349 are kept reserved both at transmitter and receiver.

356 controls (old behaviour until this option is available).
358 When enabled, the multiple HDA codecs may set the device
359 field in control (mixer) element identifiers. The use
360 of this field is not recommended and defined for mixer controls.
362 The old behaviour (Y) is obsolete and will be removed. Consider
363 to not enable this option.
