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).

Say Y to enable Silent Stream feature.
