Sonos 音响条对不上嘴型,或者看电视时断音?Sonos 音響條對不上嘴型,或者看電視時斷音?Sonos Soundbar Lip Sync Off or TV Audio Cutting Out? Fix It in Order

你是哪一种症状？先分清这三种你是哪一種症狀？先分清這三種Which of the three symptoms do you have?

持续偏移——声音一直早或一直晚,固定量。这类是延迟补偿问题,电视上有设置可以调。逐渐漂移——刚开始对得上,看久了越差越远。这类是时钟不同步,通常和音频格式或串流源有关。间歇断音——声音突然没了一两秒再回来。这类是 HDMI 握手或线材问题。三种的解法完全不同,先分清能省很多时间。持續偏移——聲音一直早或一直晚，固定量。這類是延遲補償問題，電視上有設定可以調。逐漸漂移——剛開始對得上，看久了越差越遠。這類是時鐘不同步，通常和音訊格式或串流源有關。間歇斷音——聲音突然沒了一兩秒再回來。這類是 HDMI 握手或線材問題。三種的解法完全不同，先分清能省很多時間。Constant offset — the sound is consistently early or late by a fixed amount. That is a delay-compensation issue and your TV usually has a setting for it. Gradual drift — it lines up at first and gets worse the longer you watch. That is a clock sync issue, usually tied to the audio format or the streaming source. Intermittent dropouts — audio vanishes for a second or two and returns. That is an HDMI handshake or cable issue. The three have completely different fixes, so naming yours first saves real time.

① eARC 握手:先确认它真的在 eARC 上① eARC 握手：先確認它真的在 eARC 上① The eARC handshake: confirm it is actually on eARC

音响条必须接在电视标了 eARC 或 ARC 的那个 HDMI 口上——不是随便哪个。很多电视只有一个口支持,而且标记很小。接错口的典型症状是「有声音但只有立体声」或者「时有时无」。接对之后,在电视设置里确认 HDMI-CEC(各家叫法不同:Anynet+、Bravia Sync、SIMPLINK、Viera Link)是开启的,eARC 也设成「自动」而不是「关」。音響條必須接在電視標了 eARC 或 ARC 的那個 HDMI 口上——不是隨便哪個。很多電視只有一個口支援，而且標記很小。接錯口的典型症狀是「有聲音但只有立體聲」或者「時有時無」。接對之後，在電視設定裡確認 HDMI-CEC（各家叫法不同：Anynet+、Bravia Sync、SIMPLINK、Viera Link）是開啟的，eARC 也設成「自動」而不是「關」。The soundbar has to be on the HDMI port labelled eARC or ARC — not just any port. Many TVs support it on exactly one port, and the label is small. The classic symptom of the wrong port is "there is sound but only stereo" or "it works intermittently". Once it is on the right port, confirm in the TV settings that HDMI-CEC is enabled (vendors call it Anynet+, Bravia Sync, SIMPLINK or Viera Link) and that eARC is set to Auto rather than Off.

握手不稳时,一个可靠的复位顺序是:关电视 → 拔音响条的 HDMI 线 → 拔电视电源等 30 秒 → 通电开机 → 再插 HDMI。顺序有意义,因为 CEC 状态是在开机握手时协商的。握手不穩時，一個可靠的復位順序是：關電視 → 拔音響條的 HDMI 線 → 拔電視電源等 30 秒 → 通電開機 → 再插 HDMI。順序有意義，因為 CEC 狀態是在開機握手時協商的。When the handshake is unstable, a reliable reset order is: turn the TV off, unplug the soundbar's HDMI cable, unplug the TV from power for 30 seconds, power it back on, then reconnect HDMI. The order matters, because CEC state is negotiated during the power-on handshake.

② 音频格式应该选 Dolby Digital 还是 PCM？② 音訊格式應該選 Dolby Digital 還是 PCM？② Which audio format should the TV send?

电视会按它以为音响条支持的格式来送流。如果协商出错,你会得到断续、爆音,或者干脆没声。在电视的音频输出设置里手动指定格式试两次:先试 PCM(最兼容,如果这样就稳了,说明是格式协商问题),再试 Dolby Digital / 自动。杜比全景声只在 eARC 且线材足够的情况下才成立。電視會按它以為音響條支援的格式來送流。如果協商出錯，你會得到斷續、爆音，或者乾脆沒聲。在電視的音訊輸出設定裡手動指定格式試兩次：先試 PCM（最兼容，如果這樣就穩了，說明是格式協商問題），再試 Dolby Digital / 自動。杜比全景聲只在 eARC 且線材足夠的情況下才成立。The TV sends whatever format it believes the soundbar supports. When that negotiation goes wrong you get stuttering, popping, or no sound at all. In the TV's audio output settings, force the format twice: try PCM first (the most compatible — if it stabilises, the problem was format negotiation), then try Dolby Digital / Auto. Dolby Atmos only holds up over eARC with a cable that can carry it.

一个常被忽略的点:串流 App 的音轨格式也算数。同一台电视上 Netflix 的 Atmos 音轨断,而普通节目不断,那不是电视的问题,是那条 Atmos 流的带宽需求超过了当前链路。一個常被忽略的點：串流 App 的音軌格式也算數。同一台電視上 Netflix 的 Atmos 音軌斷，而普通節目不斷，那不是電視的問題，是那條 Atmos 流的頻寬需求超過了當前鏈路。One point that gets missed: the streaming app's track format counts too. If Atmos tracks on Netflix stutter on the same TV where ordinary programmes are fine, that is not the TV — it is that Atmos stream exceeding what the current link can carry.

③ 要不要关掉电视自带的音频处理？③ 要不要關掉電視自帶的音訊處理？③ Should I turn off the TV's own audio processing?

电视上的「音效增强」「虚拟环绕」「自动音量」「夜间模式」都会引入额外延迟,而且延迟量还会随内容变化——这正是「逐渐漂移」的常见来源。既然你已经有音响条,这些处理没有存在意义,全部关掉。同时把电视扬声器设为关闭或「仅外接」,避免两套输出叠加产生回音式的错位。電視上的「音效增強」「虛擬環繞」「自動音量」「夜間模式」都會引入額外延遲，而且延遲量還會隨內容變化——這正是「逐漸漂移」的常見來源。既然你已經有音響條，這些處理沒有存在意義，全部關掉。同時把電視喇叭設為關閉或「僅外接」，避免兩套輸出疊加產生迴音式的錯位。The TV's sound enhancement, virtual surround, auto volume levelling and night mode all add latency, and the amount varies with content — which is a common source of gradual drift. Since you already have a soundbar, none of that processing earns its place; switch it all off. Also set the TV speakers to off or external-only, so two outputs do not stack into an echo-like misalignment.

处理关完之后,再用电视自带的「音频延迟 / 唇音同步」滑杆做最后微调。顺序很重要——先关处理再调延迟,否则你调的是一个会变化的量。處理關完之後，再用電視自帶的「音訊延遲 / 唇音同步」滑桿做最後微調。順序很重要——先關處理再調延遲，否則你調的是一個會變化的量。Only after the processing is off should you use the TV's own audio delay or lip-sync slider for the final trim. The order matters: switch off processing first, otherwise you are calibrating against a moving target.

④ 线材和接口④ 線材和接口④ Cable and port

eARC 需要的带宽比普通 HDMI 音频高。用音响条原配的那条线——它是按规格配的。如果原配线不见了或者你换了长线,确认新线标注为 High Speed with Ethernet 或更高等级;劣质长线在 eARC 上的典型表现就是间歇断音。也别经过 HDMI 分配器或切换器,那些设备对 eARC 的支持普遍不完整。eARC 需要的頻寬比普通 HDMI 音訊高。用音響條原配的那條線——它是按規格配的。如果原配線不見了或者你換了長線，確認新線標註為 High Speed with Ethernet 或更高等級；劣質長線在 eARC 上的典型表現就是間歇斷音。也別經過 HDMI 分配器或切換器，那些裝置對 eARC 的支援普遍不完整。eARC needs more bandwidth than ordinary HDMI audio. Use the cable that shipped with the soundbar — it was specified for the job. If it has gone missing or you swapped in a longer run, confirm the replacement is rated High Speed with Ethernet or better; a poor long cable on eARC shows up precisely as intermittent dropouts. Avoid HDMI splitters and switchers too, as their eARC support is widely incomplete.

换线是这一步里唯一能真正证伪的动作:借一条已知完好的短线直连,如果断音消失,原因就定了。換線是這一步裡唯一能真正證偽的動作：借一條已知完好的短線直連，如果斷音消失，原因就定了。Swapping the cable is the only genuinely falsifying test in this step: borrow a known-good short cable and connect directly. If the dropouts stop, you have your answer.

⑤ 为什么分组之后延迟会变大？⑤ 為什麼分組之後延遲會變大？⑤ Why does grouping add more delay?

把音响条和其他房间分组之后,系统要为多房间同步预留缓冲,电视音频的延迟会明显增加。这是设计取舍,不是故障。看电视时把音响条从组里拆出来单独用,唇音会立刻正常。如果你确实想全屋一起听电视,预期就要接受这个延迟。把音響條和其他房間分組之後，系統要為多房間同步預留緩衝，電視音訊的延遲會明顯增加。這是設計取捨，不是故障。看電視時把音響條從組裡拆出來單獨用，唇音會立刻正常。如果你確實想全屋一起聽電視，預期就要接受這個延遲。Once the soundbar is grouped with other rooms, the system reserves buffer for multi-room sync and TV audio latency rises noticeably. That is a design trade-off, not a fault. Ungroup the soundbar while watching and lip-sync returns immediately. If you genuinely want the whole house on TV audio, that delay is the price.

完全没声音，和断音是同一个问题吗？完全沒聲音，和斷音是同一個問題嗎？No sound at all — is that the same problem?

如果是从头到尾一点声都没有,先别看延迟那一套。按这个顺序:确认电视音频输出选了外接音响而不是内置扬声器;确认音响条在 Sonos App 里显示为「电视」输入而不是在播音乐;确认它没有被静音或被编进另一个组。这三样占了「完全没声」的绝大多数。如果是從頭到尾一點聲都沒有，先別看延遲那一套。按這個順序：確認電視音訊輸出選了外接音響而不是內置喇叭；確認音響條在 Sonos App 裡顯示為「電視」輸入而不是在播音樂；確認它沒有被靜音或被編進另一個組。這三樣佔了「完全沒聲」的絕大多數。If there is no sound at all, set the delay material aside. Go in this order: confirm the TV's audio output is set to the external system rather than its built-in speakers; confirm the soundbar shows the TV input in the Sonos app rather than playing music; and confirm it is neither muted nor pulled into another group. Those three cover the large majority of "no sound at all" cases.

如果音响条根本不出现在 Sonos App 里,那是网络问题不是电视问题,先去看音箱不出现那一篇。如果音響條根本不出現在 Sonos App 裡，那是網絡問題不是電視問題，先去看音箱不出現那一篇。If the soundbar does not appear in the Sonos app at all, that is a network problem rather than a TV problem — start with the speakers-not-showing-up guide instead.

按这个顺序试按這個順序試The order to work through

1. 确认接在标了 eARC/ARC 的那个 HDMI 口,并开启 HDMI-CEC。確認接在標了 eARC/ARC 的那個 HDMI 口，並開啟 HDMI-CEC。Confirm it is on the port labelled eARC/ARC and that HDMI-CEC is enabled.
2. 关掉电视上所有音效处理,电视扬声器设为关闭。關掉電視上所有音效處理，電視喇叭設為關閉。Turn off every audio processing option on the TV and set the TV speakers to off.
3. 音频格式先强制 PCM 试一轮,再试 Dolby Digital。音訊格式先強制 PCM 試一輪，再試 Dolby Digital。Force the audio format to PCM for one round, then try Dolby Digital.
4. 做一次电源顺序复位:关电视 → 拔 HDMI → 断电视电源 30 秒 → 开机 → 插回 HDMI。做一次電源順序復位：關電視 → 拔 HDMI → 斷電視電源 30 秒 → 開機 → 插回 HDMI。Run the power-order reset: TV off, unplug HDMI, unplug the TV for 30 seconds, power on, reconnect HDMI.
5. 换一条已知完好的 HDMI 线直连,不经分配器。換一條已知完好的 HDMI 線直連，不經分配器。Swap in a known-good HDMI cable connected directly, with no splitter in between.
6. 最后才用电视的唇音同步滑杆微调。最後才用電視的唇音同步滑桿微調。Only then use the TV's lip-sync slider for the final trim.

每步之后看一段真实节目再判断,不要只看几秒测试画面——格式协商和处理延迟都要几十秒才稳定下来。每步之後看一段真實節目再判斷，不要只看幾秒測試畫面——格式協商和處理延遲都要幾十秒才穩定下來。After each step, watch a real programme before judging rather than a few seconds of test material — format negotiation and processing latency both take tens of seconds to settle.
