Hisense TV no sound? Check if TV is muted – press Mute button on remote. Then go to Settings > Sound > Audio Output and select TV Speakers. If using HDMI, try a different HDMI port. Power cycle: unplug TV for 60 seconds, plug back in. Check volume isn’t at zero.
Why Is My Hisense TV Silent?
Hisense TV sound issues occur when audio output is set to external speakers, TV is muted, HDMI-CEC conflicts exist, or there are software glitches. The TV may also automatically switch audio output when devices are connected.

- Check source device audio settings
Method 8: Check Audio Format
Wrong format causes no sound.
