SEAL Dynaudio sounds flat: focus and volume settings
Open Settings → System → Audio to check Dynaudio Focus, Dynaudio Sound and Volume Adjusted with Speed. Start by comparing the built-in sound modes with one familiar track. There is no single best equaliser preset for every listener or recording.

- While parked, play a familiar track at a comfortable volume and open Settings → System → Audio. Note your current choices so you can return to them.
- Compare Dynaudio Focus → Whole with Driver if you usually listen alone. Whole, Front Passenger, Rear, Surrounding and Customize serve different listening positions; use the setting that suits the occupied seats.
- Compare the Acoustic, Dynamic, Soft and Speech sound modes using the same passage. Change one setting at a time rather than raising every equaliser band.
- Check Volume Adjusted with Speed. Zero switches compensation off; levels one to seven apply increasingly strong adjustment as speed changes. The handbook gives four as the default. Choose a setting before your next ordinary journey and judge it without operating the screen while driving.
- If the sound remains unexpectedly thin or uneven, compare another recording and another already-working source, such as radio versus phone audio. This comparison helps distinguish a source-specific problem from a setting or speaker issue.
What success looks like
Changing focus or sound mode produces an audible change and you can choose a balance you prefer. Speed compensation affects adjustment as speed changes; it is not a promise that a stationary track will become louder.
If that did not work
If only phone audio sounds wrong, check the phone and audio app’s own sound settings before changing the speakers. If one side stays silent or distorted across sources with Whole focus selected, ask BYD to check that speaker channel and its connection. Report the affected position, source and settings, and whether the problem occurs at ordinary listening volume. Owner equaliser presets are preferences, not evidence that every SEAL has the same fault.
