bool "Enable Silent Stream always for HDMI"
depends on SND_HDA_INTEL
help
Intel hardware has a feature called 'silent stream', that
keeps external HDMI receiver's analog circuitry powered on
avoiding 2-3 sec silence during playback start. This mechanism
relies on setting channel_id as 0xf, sending info packet and
preventing codec D3 entry (increasing platform static power
consumption when HDMI receiver is plugged-in). 2-3 sec silence
at the playback start is expected whenever there is format change.
(default is 2 channel format).
Say Y to enable Silent Stream feature.
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.
