+ 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).
