Dell AC511 Troubleshooting

The soundbar does not create audio or playback once plugged into a device.

Ensure that both the USB plug and port are clean of dust and small debris. Debris may interfere with the port's ability to transmit power or data.

Check that the output device is also plugged in and receiving power. The Dell AC511 is powered by its USB connection to the output device, so if the device is not receiving power, the speaker cannot either.

Try using a different USB cable. The one you are using may not be functioning properly.

The soundbar's outer shell has cracks or is missing portions.

The soundbar is not designed to be dropped from large heights or hit by heavy objects. Refrain from these actions, as they may damage the outer shell of the speaker. If damage does occur, such as cracking or parts being missing, cover the afflicted area until the relevant parts can be replaced. Try to avoid further damage in the same area.

The soundbar does not stay connected when plugging in the USB cable.

Ensure that both the port and plug are clean of debris and small items. Obstructions may prevent the USB cable from plugging in securely.

Check that the USB plug is not physically deformed or damaged. If the USB plug is unable to be reformed with tools or is missing completely, you may need to order a replacement part and install it.

The soundbar creates static or scratchy audio playback once connected.

Ensure that both the USB plug and port are clean of dust and small debris. Debris may interfere with the port's ability to transmit data.

Try using a different USB cable. The one you are using may be broken or not functioning properly.

Check that the device is fully connected properly.

Verify that the speaker is being properly detected by the system. If it isn't, it may be receiving garbage noise or improperly encoded audio.

Check for damage on the front panel of speaker which could lead to a buzzing noise. You may need to replace the front panel if it is cracked or broken.

The soundbar does not produce audio when connected.

Make sure that the device is properly connected to the system. Even if it's plugged in, your device may not be outputting audio to it.

Ensure that there is little to no damage to the external wiring. Damaged cables may not transmit data properly.

Try turning the external volume knob. It may be set to low or zero volume.

It may be the case that the internals of the volume knob are set to a low volume, and the external knob itself is disconnected and unable to adjust it. If the knob does not properly adjust volume, you should replace it.
