Sony WF-1000XM6: check LDAC that is not active
Sony WF-1000XM6 — Separate source support, Classic Audio and the required quality mode.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Exact WF-1000XM6. Classic Bluetooth A2DP music; LDAC is not the LC3 codec of an LE Audio connection.
Connection scope: Bluetooth. Symptom: An option or codec is missing.
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 source-ldac. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
source-ldac
Does the exact source document LDAC music transmission?
Headset support alone cannot add LDAC to an unsupported source.
Look for: Choose only what you can confirm.
- If Yes, confirmed → Is this a Classic A2DP music connection rather than LE Audio?
- If No → Continue with model-specific support
- If I do not know / cannot check → Confirm the missing detail first

classic
Is this a Classic A2DP music connection rather than LE Audio?
LE Audio uses LC3; do not force a Classic codec in that connection.
Look for: Choose only what you can confirm.
- If Yes, confirmed → Select the documented sound-quality priority
- If No → Continue with model-specific support
- If I do not know / cannot check → Confirm the missing detail first

quality
Select the documented sound-quality priority
In Sound Connect Bluetooth Connection Quality select Priority on Sound Quality, if that exact control is available.
Look for: Complete this one check, then report the observation.

source-setting
Check the source’s documented LDAC configuration
Use the exact source operating instructions for its codec control. If support, menu or active-codec observation is unknown, stop rather than copy another phone’s developer options.
Look for: Complete this one check, then report the observation.
- If I completed this step → Can you confirm the active connection now uses LDAC?
- If I cannot follow this step → Continue with model-specific support
- If I do not know / cannot check → Confirm the missing detail first

codec
Can you confirm the active connection now uses LDAC?
A product feature badge or quality preset alone does not confirm the negotiated codec.
