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 step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Is dialogue quiet relative to a soundtrack already at a comfortable overall level?
All sound quiet or a missing centre speaker has a different path.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is DTS:X playing with Dialog Control actually available and below +6 dB?

step-1

- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown
