Follow these troubleshooting steps to resolve the issue:
- Set the RF Channel to Off, then back On
- Select Setup → Advanced Settings → Speaker Settings → Wireless Speaker Settings → RF Channel to Off, then set to On.
- We recommend the RF Channel setting is set to On (default setting: On). The Soundbar automatically selects the best channel for transmission when RF Channel is set to On, which makes it stronger against wireless interference.
- If the sound issue persists, turn Off the setting.
- After changing the RF Channel settings, it may take one minute to reconnect.
- The frequency setting is deleted after disconnecting the power cord. If you disconnect the power cord for some reason, switch RF Channel from Off to On again.
- Set the Wireless Playback Quality to Priority on Stable Connection
- Select Setup → Advanced Settings → Speaker Settings → Wireless Speaker Settings → Wireless Playback Quality to Priority on Stable Connection.
- Set the distance between a wireless LAN router, the control box, and the speakers at least 1.5 m (5 ft) from any wireless LAN router (a).
Note: The issue can be improved by changing the wireless LAN router antenna’s direction or angle.
If walls block two sides of the speaker, the communication environment will be poor, and the sound may be interrupted. Refer to examples 1 to 3 to move the speaker away from the wall or turn it to make space between the walls.
Example that walls block the two sides of the rear speaker:
Example 1: Move the speaker more than 5 cm (2 in) away from the side of the wall:
Example 2: If the speaker cannot move away from the side wall, move it more than 10 cm (4 in) away from the rear wall:
Example 3: If the speaker cannot move away from the corner of the wall, turn it about 45 degrees to make space from the wall:
- Check the control box installation condition and wireless environment:
- If a device that generates electromagnetic radiation is nearby, such as a wireless LAN device or microwave oven, move the speaker system away from that device.
- Turn off any other wireless LAN devices not in use to reduce interference, and check if the issue is resolved.
Note: If the issue is resolved, change the device's network connection from wireless LAN to wired LAN, if possible.
- If the control box and speakers are too far away from each other. Bring them closer together.
- Remove or move any obstacle between the control box and the speakers.
- Make sure the control box front panel display is not hiding.
- Move the control box, change the direction of the control box, or install the control away from a TV.
- Interference between the network connection and speaker connection may occur. Try one of the following:
- Change the control box's and router's wireless LAN connection to a wired LAN connection.
- Switch the band of the wireless LAN router to 2.4 GHz, then set up the wireless network connection between the speaker system and the wireless LAN router again using a 2.4 GHz band.
- Reset the speaker system.
Note: For details on how to reset the speaker system, refer to the Help Guide.
