config SND_HDA_INTEL_HDMI_SILENT_STREAM |

bool "Enable Silent Stream always for HDMI" |

depends on SND_HDA_INTEL |
|
help |
|
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. |
