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

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365 The old behaviour (Y) is obsolete and will be removed.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