Ensure both the AK3040C and your connected audio device (headphones/speakers/source) are fully charged.
Verify that the 3.5mm audio cable is securely connected to both the AK3040C and the audio source/output device.
Check that the AK3040C is in the correct mode (TX for transmitting, RX for receiving).
Confirm that your Bluetooth headphones/speakers are properly paired with the AK3040C (in TX mode) or that your source device is paired with the AK3040C (in RX mode).
Adjust the volume on both the AK3040C and the connected audio device.
Move the devices closer to each other to ensure they are within the 10m communication range.
Restart both the AK3040C and the connected audio devices.

Difficulty Pairing

Ensure the AK3040C is in pairing mode (indicator light flashing).
Make sure your other Bluetooth device is also in pairing mode.
Clear previous Bluetooth connections on both devices and attempt to pair again.
Reduce interference by moving away from other wireless devices (Wi-Fi routers, other Bluetooth devices).

Audio Latency (Delay)

While the AK3040C supports APTX-Adaptive and APTX LL for low latency, some factors can still introduce delay:

Ensure both the AK3040C and your connected headphones/speakers support APTX Low Latency or APTX-Adaptive codecs. If one device does not, it will default to a higher latency codec like SBC.
The audio source itself might introduce delay (e.g., some projectors or older TVs).
Environmental interference can affect latency.
