(請益)Yamaha RX-A3050和電視的接法

bokicat

環擴A3050不支援Dolby Vision/HDR10+ HDMI OUT只有2.0b (ARC)
三星電視支援HDR10+雖然HDMI也是2.0b，但是有HDMI IN (eARC)和另外兩個HDMI IN
要接的設備有Oppo UDP-203 (可影音分離) / Apple TV 4K 2022 / PS5 / Philips hue HDMI Sync Box (四進一出，HDMI 2.0b，支援DV和HDR10+)

三星的HDMI IN (eARC)則連接到環擴的HDMI OUT 1 (ARC)，UDP-203影音分離一條AUDIO ONLY直接接到環擴的HDMI IN1 (BD)，一條MAIN接到Philips hue HDMI Sync Box，因為要有Philips hue的燈光同步效果，所有的設備都先接在這個Sync Box，然後再接到三星的HDMI IN2

請問有比較更好的接法嗎？因為環擴這端只有ARC，好像不能接收回傳Atmos/DTS-X來解碼。

還是我需要另外多買一個HDMI2.1 eARC的影音分離器，類似大通的HA2-320es，把所有設備機先接在上面，然後一條HDMI OUT給顯示設備，另一條HDMI AUDIO給環擴？

感謝指教。

That's a tricky setup! It sounds like you're really trying to squeeze the most out of your gear. Since your receiver lacks full eARC support, getting Atmos/DTS-X back from the TV is definitely a hurdle. The HDMI 2.1 eARC splitter could be a good solution, letting you route audio directly to your receiver. It reminds me of how my Granny used to solve tech problems – with clever workarounds and a bit of ingenuity! Keep researching those splitters, it might be your best bet for the immersive audio you're after. Good luck!

I faced a similar issue with an older AV receiver and a Samsung TV. ARC worked for basic Dolby Digital, but Atmos and DTS:X from TV apps were unreliable, especially with eARC-only sources. Your current setup is sensible, though routing everything through the Hue Sync Box may limit newer formats. Before buying another splitter, check whether the A3050 supports compressed Atmos through ARC and whether the TV can pass it correctly. A practical way to compare real-world setups is to browse Fnaf platform discussions, where users often share compatibility tests and wiring results.
