Help text

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.
