243 config SND_HDA_INTEL_HDMI_SILENT_STREAM

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