BYD CarPlay or Bluetooth audio stops after a phone call
If music does not return after a call, first end any remaining call or voice session and select the intended audio output. Then return the car to the right media source and check media volume, which can differ from call volume.
- Park before using the screens.
- End the call and check that no voice assistant or voice-message session remains active. Safety note: Wait for an active OTA installation to finish before restarting. Keep another authorised access method if removing a phone pairing, particularly when that phone is also a Digital Key; a vehicle factory reset or 12V disconnection is not needed for these checks.
- Use the phone’s audio-output control to select BYD, CarPlay or Android Auto rather than earbuds or the phone speaker.
- Select the intended media source on the car.
- For ordinary Android Bluetooth audio, open Settings → Connected devices (or Bluetooth), open the settings beside your BYD, and enable Media audio for music. If calls are the missing sound, check Phone audio there instead. Phone makers may use different labels; these are Bluetooth checks, not an iPhone or Android Auto menu path.
- Raise media volume to a normal listening level.
- Close and reopen the affected app, then reconnect phone projection using its ordinary control.
What to expect
After the call ends, music plays through the selected car source at the intended media volume and a new call uses the intended output. If projection works but sound does not, report the audio path separately.
If that did not work
- Radio works but Bluetooth music does not: check Media audio, both volume controls and whether another paired device is receiving the sound.
- Music works but Bluetooth calls do not: check Phone audio and the call’s selected output. A working music connection does not confirm that calls use the same output.
- The whole CarPlay or Android Auto screen disconnects: use the matching projection guide below rather than treating it as only an audio-volume problem.
- The same failure follows calls on more than one supported phone: ask BYD to reproduce that sequence and check the infotainment software.
Give support the phone/OS and vehicle versions, connection type, affected call or media source, and what restored sound. Mention when it began without assuming an update caused it.
Narrow down the affected source
If native radio works but one phone app does not, focus on that session rather than assuming the speakers failed. Compare wired and wireless only if your exact setup supports both. For wired CarPlay, compare a compatible data cable and port. For wireless CarPlay, check Bluetooth, Wi-Fi and Auto-Join for its network.
If the session remains stuck
Once updates have completed, restart the phone and display using their normal controls. Keep the original connection details before forgetting and setting up the car again.
