Follow these checks in Audio Fix →

When this guide applies

Exact WiiM Amp Ultra, WiiM Amp Pro and WiiM Ultra. Shared documented WiiM Home operation; identify the actual unit before changing its setting. Actual Bluetooth input and its installed Playback Latency control visible; original value retained, user accepts a possible stability trade-off. Only normal external user controls; no reset, firmware installation, internal repair, mains alteration or earth lifting.

Connection scope: Bluetooth. Symptom: Sound and picture are out of sync.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

Checks and possible outcomes

Start at scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

scope

Confirm the exact setup

Is video sound late through this exact unit’s Bluetooth input, Playback Latency visible above its available minimum, and do you accept a small lower-delay comparison that may introduce stuttering?

Look for: Choose only a detail you can confirm.
