Did you solve it? Me too.

The phone is connected to the Bluetooth speaker and there is no sound Solution:

1. Bluetooth disconnection.

If we find that when listening to a song or playing **, the Bluetooth headset suddenly does not make a sound. Take off the headphones and notice that the sound is coming from the phone's speaker or earpiece. At this time, the Bluetooth connection may have been disconnected.

At this time, enter the Bluetooth interface and find that the paired earphones are not displayed in use, for calls and**, then the Bluetooth connection has been cut off, at this time, we need to click on the headset again in the Bluetooth interface, let the mobile phone re-initiate the connection to the headset, and after reconnecting, put on the headset and listen to the song!

2. Environmental interference.

This situation often occurs in areas with dense or large WIFI usage, where Bluetooth and WIFI, Zigbee and other channels are in the same vicinity of the GHz frequency band.

When our phones and headphones are in this environment, the Bluetooth connection established between the phone and the headphones is relatively susceptible to interference from the wireless environment, and this situation may also be encountered in places with many roadside cameras. If you encounter a situation where the Bluetooth sound is stuttering and silent in these scenarios, try to leave these areas and the sound will return to normal.

3. Keep Bluetooth headsets and mobile phones away.

When the Bluetooth headset listens to the sound, the mobile phone sends audio packets to the headset through the antenna, this sending power has a certain limit, if the mobile phone and the headset are far away, then the signal of the mobile phone received by the headset will be relatively weak, so it will cause a certain degree of packet loss, resulting in the sound heard by the headset is intermittent, remember to use the Bluetooth headset, don't be too far away from your mobile phone!

4. The headset status is abnormal.

Sometimes, the sound heard in the earphones is suddenly silent, or the noise is suddenly very loud, but in the Bluetooth interface, the Bluetooth is still connected normally, which may be that the earphones have entered an abnormal state. At this time, try to unpair the earphones on the Bluetooth interface, and then pair them again to connect the earphones. If the headset continues to be in this state after unpairing, you can report this problem to customer service.

5. The volume setting is too small for the earphones to hear.

In fact, in the process of Bluetooth**, mobile phones and headphones can control the volume, if the volume is turned up on the mobile phone side does not work, if the headphones also have volume adjustment buttons, turn up the sound on the headphone side, and you should be able to listen to songs normally.

If the Bluetooth headset is relatively small (for example, many TWS earphones) do not have a volume adjustment button, try to set the **Volume Sync (coloros and later supported) switch on the advanced settings in the upper right corner of the Bluetooth interface on your phone, and then listen to ** to turn up the sound.

6. The abnormal call of the application causes the Bluetooth to output no sound.

Some apps will unusually occupy the phone's audio channel after opening, which may prevent other apps (such as **, etc.) from sounding through Bluetooth**. If there is a sound abnormality such as ****, it is after a specific app is opened and used, you can try to clean up other apps in the multitaskbar, and then try ****.
