What to Do When There's No Sound for WeChat Voice Calls via Car Bluetooth?
2 Answers
First, locate and turn on the car Bluetooth. In the car Bluetooth settings interface, enable auto-connect and auto-answer, then activate Bluetooth. After connecting your phone's Bluetooth to the car Bluetooth, tap on the car Bluetooth. In the Bluetooth settings page, turn on both call audio and media audio.
I struggled with this issue for a long time last time, sharing a few tested and effective methods. First, confirm whether your phone's Bluetooth is actually connected to the car system. Sometimes it shows as connected, but the channel hasn't switched over—try re-pairing it in the car system settings. Then, focus on your phone settings: Android users need to go to "App Management" and enable "Microphone" permission for WeChat, while iPhone users should check in settings if WeChat's microphone permission was accidentally turned off. Another common pitfall is that the media volume isn't turned up—try increasing your phone's media volume separately after connecting via Bluetooth. Some cars require manually switching the audio source to Bluetooth; look for a button with a musical note symbol on the steering wheel. The ultimate solution is to reboot—hold down the car system's power button for 10 seconds to force a restart, and also restart your phone. This solves 90% of the problems. Remember, deleting old pairing records and reconnecting often yields better results.
