Sound issues

If you face issues related to the sound of your projector, please read the instructions below:

No sound from the external connected device:

• Check if your projector is not set to "MUTE"
• Check if the speaker is activated
• If you're screen mirroring, ensure the volume of the source is at its highest
• Ensure the USB stick or Micro SD card is not bent or broken
• Turn off both your projector and then turn it on again
• While playing a music file from the multimedia player, ensure to use one of the following supported file formats: .mp3, .wav, .rm, .m4a, .mka, .ra, .ape,. adts, .wma, .divx, .ogm, .trp, .tp, .ac3, .aac, .amr, .flac, .m4r, .mmf, .mp2, .ogg, .wv, .flac, .ogg

The sound is distorted or not synchronized to the picture

• The available Wi-Fi bandwidth is insufficient for sending the video flawlessly from your smartphone to your projector. This can happen if one or more Wi-Fi networks operate in the same frequency range nearby. Certain IoT devices (e.g. ZigBee enabled devices) also operate in this frequency range
• Your smartphone is not fast enough to compress the screen data and send it simultaneously over Wi-Fi
• Your smartphone may maintain parallel connections to your home network and your projector. This will reduce the available bandwidth. Disabling temporarily the connection to your home network may help

If the problem persists follow these steps: 

1. Turn the projector off by pressing Power on the side of your projector 
2. Wait at least 10 seconds 
3. Turn the projector on by pressing Power once on the side of your projector
4. If the problem persist again, please contact our technical service centre by sending an email to support@screeneo.com or your dealer
