Here is a list of steps to help troubleshoot audio dropouts on Smart TVs:

1. Ensure that the audio/video cables are firmly connected to the TV and source device.
2. Check the volume level on the TV and the source device and make sure it is not set to minimum.
3. Restart the TV and input devices like the streaming box or game console.
4. If connected to a soundbar, use the soundbar’s remote to adjust the volume.
5. If still experiencing audio dropouts, try connecting the HDMI source device directly to the television and bypassing the soundbar, if applicable.
6. Try a different HDMI cable. Even if the cable appears to be connected securely, faulty cables can cause issues.
