What to Do When There's No Sound for WeChat Voice Calls via Car Bluetooth?

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.
It's so frustrating when you can't hear WeChat voice messages while driving. Try these quick fixes. First, press the call button on the steering wheel to see if it can activate the voice channel. If you see "Media" or "Bluetooth Audio" icons on the car's screen, tap them immediately—many cars default to radio mode. Quickly glance at your phone: Android users can pull down the notification bar to see a "Media audio disconnected" prompt and tap to reconnect; iPhone users can swipe up to the Control Center, firmly press the music module's top-right corner, and select the car system's name. Here's a hidden trick: during a WeChat voice call, turn the car's volume knob all the way down and then slowly increase it—sometimes this fixes volume cache glitches.
