2. Make sure if you have selected to correct input source. You could short press the INPUT button to switch the input source.

3. Ensure the volume knob is in an appropriate position.

4. Under TX mode (Bluetooth multipoint pairing), the 2 connected devices cannot output at the same time for LDAC and aptX LL codecs.

5. Under TX mode (USB-in), what can be done if there is no sound(The Windows computer has recognized the BTA30Pro):

【Uninstall Driver off the computer】

On the bottom right corner of the computer display: Click the mouse on right to call for Playback device - Properties- General- Driver- Uninstall the Driver. After uninstalling it, unplug and re-plug the data cable.

6.Check if there are bad contacts by unplugging and plugging the adapter cable or changing it. Ensure the cable is connected appropriately.

7.Click the LL/HD button to switch Bluetooth codec. If it is switched to a codec that the Bluetooth receiver does not support, there will be no sound when playing music.

8. Only having sound under LDAC, no sound after switching to APTX or other codec:

Check whether the other Bluetooth codecs are selected in the FiiO Control APP.

How to do if no sound in coaxial/optical output mode

1.Please check the supported sampling rate of the device connected to the BTA30Pro. The optical output of BTA30Pro supports up to 192kHz . The coaxial output supports up to PCM384KHz/Dop128. There will be no sound if the sampling rate of the music file surpasses that of the device.

2.Check if the ‘Digital up-sampling’ switch on the FiiO Control app is turned on. When it is on, all music under 192kHz will be output at 192kHz.Music above 192kHz will be output at the sampling rate of the music.There will be no sound if the device connected to the output end of the BA30Pro does not supported the output sampling rate. It is suggested to turn off the Digital up-sampling switch at that time.

3.Generally, the output can be switched freely to line-out, coaxial out and optical out. If there is only one output that is normal, it means this port is having an issue.

Fail to connect via Bluetooth

It is suggested to clear the pairing records of both the BTA30Pro and the Bluetooth receiving device and then reconnect them.
