Chosen Solution
For the past 2 weeks I have not been able to listen to anything on my tablet when using headphones. The speakers work just fine, but nothing comes through the headphones. I don’t know what to do.
There could be a problem with the headphones themselves. Try testing them on another device. If the problem still occurs refer to the link below for additional solutions. HP 7 Plus 1302 Troubleshooting
Make sure the sound is on, and loud enough in your tablet setting.
You need to put the earplugs in your ears.
