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
