• Only one audio cable connection is required.
• Some TVs may mute their internal speakers when an external audio device is connected. This is a TV feature, not a headset malfunction. Consult your TV's manual for options to enable simultaneous audio output.

Resolución de problemas

Sen son dos auriculares

• Check PCM Setting: If using an optical connection, ensure your TV's audio output format is set to PCM.
• Verificar a conexión do cable: Confirm that only one audio cable (optical, RCA, or 3.5mm) is correctly connected from your TV/AV device to the transmitter.
• TV Audio Output Settings: Access your TV's audio settings menu. You may need to activate the TV's audio output for external speakers (e.g., select "External TV Speakers" or "Audio Out"). Refer to your TV's user manual for specific instructions.
• Adjust Source Volume: Increase the volume on your TV or connected AV devices (cable box, set-top box) to a sufficient level.
• Minimizar a interferencia: Position the transmitter as far as possible from other Wi-Fi devices, especially your Wi-Fi router, to prevent signal interference.
• Test Audio Source: To confirm your TV is producing sound, connect a standard wired headphone directly to the TV's audio output. Alternatively, test the SIMOLIO unit with a mobile phone or PC to verify its functionality.

TV Speakers Mute When Headset is Used

• This behavior is dependent on your TV's design. Consult your TV's user manual or contact the TV manufacturer to determine if simultaneous audio output is supported.
• Many modern TVs allow internal speakers and external audio devices to operate concurrently. For example, some LG TVs offer an option like "Internal TV Speaker + Audio Out (Optical)", and some Samsung TVs allow selecting "TV Speaker" from audio output lists.
• If your TV is an older model that mutes internal speakers when an external audio device is connected, and you primarily watch content from a single fixed AV device (e.g., a cable box), you can connect the SIMOLIO unit directly to that AV device instead of the TV.
