A:Answer Hi Virgusa,
The Volume level to be able to hear normally usually all depends on your personal preferences. Also, some sources have their own volume control, which might be set too low or too high. Please check the volume control of the external device (cable box or satellite box, DVD, Blu-ray, etc.) connected to your TV. Also, check the cable connection between an external device and the TV and then try the cable connection again.
There are also a few Volume Features that you may want to review to improve your experience:
1. Auto Volume automatically adjusts the sound to a certain level when changing channels or switching to another external input. Go to Settings > Sound > Expert Settings > Auto Volume = On.
2. Adaptive Sound automatically adjusts to a specific volume level while watching TV. The TV analyzes your volume usage history by time period to automatically adjust the volume when you use an app or switch to an external input source. Go to Settings> Sound> Sound Mode> Adaptive Sound.
3. Several Sound Modes are likewise available to meet your personal preferences: Home > Settings > Sound > Sound Mode.
I hope this helps! For more assistance, please call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
