    唔洗咁麻煩啦,你關咗部Amp電視就有番聲出啦,但用ARC你開電視部AMP會自動跟住開(我部AMP是LX73,唔知你果部會唔會).

係唔係新電視先有呢個功能？幾年前嗰啲未有？

大約三年前 HDMI 1.4 後有, 我部 Onkyo 5008 大約係兩三年機

AV機絕大部份是日本機, 基本上相信和日本電視 (及飛仔) 配合。  同韓國機就唔敢講

Onkyo 5008 說明書講明同以下配合

Panasonic Viera link compatible
Toshiba REGZA link compatible
Sharp (個別形號)


說明書好明顯冇提到 Sony, 唔知點解...

    ARC(Audio Return Channel聲音回傳功能)是随著HDMI 1.4開發的新功能,
在2010年打後出的電視及器材先至有.

HDMI 1.3 應該唔得, 1.4 可以試試

    For my case of Sony TV with Onkyo Amp, I will have sound from AMP if I touch the AMP's volume.  Once I touch the TV's Volume, the AMP will be mute verse is same.

http://en.wikipedia.org/wiki/HDMI#ARC_and_HEC

HDMI 1.4 introduces two features called ARC (Audio Return Channel) and HEC (HDMI Ethernet Channel).[81][82][116] These features use two pins from the connector: a previously unused pin and the hot plug detect pin.[116]
ARC is an audio link meant to replace other cables between the TV and the A/V receiver or speaker system.[81] This direction is used when the TV is the one that generates or receives the video stream instead of the other equipment.[81] A typical case is the reception of ATSC or DVB signals by a TV, but reproduction of audio is handled by the other equipment.[81] Without ARC, the audio output from the TV needs to be routed by another cable, typically TOS-Link or coax, into the speaker system.[81]
HEC provides a bidirectional Ethernet communication at 100 Mbit/s.[82] It also goes by the name HEAC (HDMI, Ethernet, Audio, Control).[116]


I'm pretty sure my Sony do not support 1.4 because it is launched before introduction of 1.4.  I was surprise the ARC work in my TV.
