The top part of the 3.5mm jack does not create sound

[lloydi12345]

For stereo sound to come out, you need all three terminals to be working.

These connectors have many names, including 2.5mm headphone plug, stereo plug, etc. Another name for it is the 2.5mm TRS plug, for Tip, Ring, and Sleeve.

Tip = Left channel
Ring = Right channel
Sleeve = Ground

So looks like the right channel is not working. Although tinitignan ko pa baka right front and speakers talaga yung hindi gumagana.
