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