NN If there is no video signal, both the TV's speakers and the external speakers will be mute. ●● Auto Volume When you change channels, video sources, or content, Auto Volume automatically adjusts the TV's volume level so that the volume level remains the same for all sources. For example, if you switch from a streaming video application to a Blu-ray player or a favorite TV channel, Auto Volume can modify the volume up to 12db to equalize the sound. The Auto Volume function has two settings: Normal and Night. Normal ◀ applies a normal level of volume adjustment. Night applies a slightly lower ▶ volume level and is ideal for late-night TV viewing. If you want to use the volume control of a connected source device to control the sound, deactivate the Auto Volume function. When you use the Auto Volume function with a source device, the device's volume control may not function properly.
