The issue with WeChat sound not going through Phone Link could be due to a few factors:
- Poor network connection: Make sure your phone and the linked device have a stable internet connection.
- Volume settings: Check the volume settings on both your phone and the linked device to make sure the sound is not muted or set too low.
- Incorrect settings: Verify that the audio output is set to Phone Link on both devices.
- Compatibility issues: Ensure that both devices support WeChat audio transmission through Phone Link.
