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