Why is the music playback silent when the POCO F7 Ultra is connected to Bluetooth earphones and the LDAC in the Developer options interface is switched to AAC?

Thank you for your continued support. This problem is caused by the earphones not supporting certain codecs, not the phone's fault. Rest assured, the device is functioning as intended, and you can continue to use it with confidence.
Note:
For optimal performance, we recommend using earphones that support the appropriate codecs to ensure seamless audio playback. Please do not force the switch in the Developer options.
