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