中文
含义
错误码ERR 5表示HDMI ARC/eARC通信故障。该代码表示声吧通过HDMI ARC（Audio Return Channel）或eARC接口与电视之间的音频回传链路异常，导致电视音频无法通过声吧播放，或声吧无法正确接收电视的音频信号。
常见原因
- HDMI线缆不支持ARC/eARC功能（需HDMI 1.4以上带以太网版本），或线缆质量差
- 电视和声吧的HDMI CEC/ARC设置未正确启用
- 电视端HDMI ARC接口的音频输出格式设置与声吧不兼容
- HDMI线缆HDMI ARC接口接触不良或端子氧化
- 声吧或电视进行了固件更新后eARC协议握手方式改变
自助排查
- 确认使用支持ARC/eARC的HDMI线缆（建议使用HDMI Premium Certified或Ultraspeed线）
- 在电视设置中确认HDMI CEC（Bravia Sync/HDMI Control）和ARC/eARC已开启
- 将电视音频输出格式从”自动”切换为”PCM”测试，排除格式兼容性问题
- 更换另一个HDMI接口（部分电视只有特定接口支持ARC/eARC），重新插拔连接
English
Meaning
Error code ERR 5 indicates an HDMI ARC/eARC communication failure. This code indicates that the audio return channel link between the soundbar and the TV via HDMI ARC or eARC is abnormal, preventing the TV’s audio from being played through the soundbar, or the soundbar from correctly receiving the TV’s audio signal.
Common Causes
- HDMI cable does not support ARC/eARC functionality (requires HDMI 1.4 or later with Ethernet), or is poor quality
- HDMI CEC/ARC settings on the TV and soundbar not properly enabled
- TV audio output format settings for the HDMI ARC port incompatible with the soundbar
- HDMI ARC port contacts oxidized or making poor contact
- eARC protocol handshake method changed after a firmware update on the soundbar or TV
Self-Check Steps
- Ensure you are using an ARC/eARC-compatible HDMI cable (HDMI Premium Certified or Ultra High Speed recommended)
- Verify that HDMI CEC (Bravia Sync / HDMI Control) and ARC/eARC are enabled in TV settings
- Switch the TV audio output format from “Auto” to “PCM” to rule out format compatibility issues
- Try a different HDMI port (only specific ports support ARC/eARC on some TVs) and reseat the connection entirely
