    I’m casting from my phone, but there’s no sound coming from my TV.

    Ensure that your phone and TV are connected to the same Wi-Fi network. Check the volume settings on both your phone and TV, and make sure they are not muted. If using an HDMI cable, ensure it is securely connected and not damaged. Try restarting both your phone and TV to resolve any temporary software glitches.

    I’ve connected my laptop to my TV via HDMI, but I’m only getting sound from the laptop speakers.

    Check the audio output settings on your laptop. Ensure that the HDMI output is selected as the default audio device. If using an external speaker system or soundbar, verify that it is properly connected to your TV and powered on.

    My streaming device is connected to my TV, but the sound is lagging.

    Consider the following: Ensure that the Wi-Fi signal is strong and stable. Move the streaming device closer to the router to improve signal strength. Check the HDMI cable connecting the device to the TV; it may be faulty or not securely connected. If the problem persists, try resetting the streaming device to its factory settings.

    When I cast from my phone, the sound is distorted or crackling.

    Check the Wi-Fi connection between your phone and TV; a weak signal can lead to audio issues. Try restarting your phone and TV to refresh software and network connections. If the sound quality is persistently poor, consider using a wired connection instead of Wi-Fi.

    I’m experiencing audio dropouts when casting from my laptop to my TV.

    A slow or unstable Wi-Fi connection can cause audio dropouts. Ensure that your laptop is close to the router or connected via an Ethernet cable for a more stable connection. Check the HDMI cable connecting your laptop to the TV, as a loose or damaged cable can interrupt the audio. Additionally, try disabling and re-enabling the Bluetooth connection on your laptop.
