Also, new soundbars and receivers from Sonos and Onkyo work well with HDMI ARC. This means they fit right into your setup.
Drawbacks of HDMI ARC
HDMI ARC’s benefits are many, but there are a few downsides:
- Compatibility Issues: Both your TV and receiver need ARC-compatible ports. Older devices might not have them.
- Audio Bandwidth: HDMI 1.4’s audio support is limited compared to eARC (Enhanced Audio Return Channel).
Even though HDMI ARC makes connecting easier, it might not give the highest audio quality. That’s where HDMI 2.1 and eARC come in. They support even better technologies, like 8K video. Making HDMI 2.1 a great choice for the future.
Which Is Better Optical Audio or Hdmi Arc
The debate on Optical Audio versus HDMI ARC matters a lot to sound lovers. HDMI ARC comes with high bandwidth, which can handle lossless audio formats. Formats like Dolby True HD and DTS-HD Master Audio work well with it. This is great for anyone wanting a top-notch home cinema. HDMI ARC also lets you connect audio with just one cable. This makes setting up your system easier and improves sound integration.
Optical Audio has its strong points too. If electronic noise is a problem, Optical Audio can help. It sends sound through fiber optic lines, keeping the quality top-notch. This is good for older setups or simpler systems. But, it often uses compressed audio formats. This might not work for all audio types like HDMI ARC does.
HDMI ARC is known for being ready for the future. It supports features like CEC and can get firmware updates. It’s great for serious home theaters. It can carry more sound channels for an in-depth experience. Think 5.2 setups or lively sports watching. But, if your setup is simple, Optical Audio could be enough. It still gives clear and quality sound.
