+# CONFIG_SND_HDA_INTEL_HDMI_SILENT_STREAM:
+#
+# 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.
+#
+# Symbol: SND_HDA_INTEL_HDMI_SILENT_STREAM [=n]
+# Type : bool
+# Defined at sound/pci/hda/Kconfig:243
+# Prompt: Enable Silent Stream always for HDMI
+# Depends on: SOUND [=m] && !UML && SND [=m] && SND_HDA [=m] && SND_HDA_INTEL [=m]
+# Location:
+# -> Device Drivers
+# -> Sound card support (SOUND [=m])
+# -> Advanced Linux Sound Architecture (SND [=m])
