Jbl playlist to tv audio

Sep 21, 2018
I connected my JBL playlist portable speaker to Samsung tv 32h4100 using audio jack male with audio out port on tv. I selected external speaker instead of tv speaker. But the sound is inaudible or very low on speaker.

When I connect the same jack to my mobile to jbl speaker it works well.

Is there any different with audio out port of tv and mobile?
