enables the feature just for the patch loader below.
If you need the traditional sysfs entries for the manual interaction,
turn on CONFIG_SND_HDA_HWDEP as well.

bool "Enable Silent Stream always for HDMI"
depends on SND_HDA_INTEL
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.
config SND_HDA_CTL_DEV_ID
bool "Use the device identifier field for controls"
depends on SND_HDA_INTEL
help
Say Y to use the device identifier field for (mixer)
controls (old behaviour until this option is available).
When enabled, the multiple HDA codecs may set the device
field in control (mixer) element identifiers. The use
of this field is not recommended and defined for mixer controls.
The old behaviour (Y) is obsolete and will be removed. Consider
to not enable this option.
