Your USB earphone may not be compatible. Which model are you using?

Am using connector....

[OptimusPrime108]

Many 3rd party USB c to 3.5 mm are not compatible.

Is there any way to solve it.... am using one plus connector for jbl earphones

What phone are you using? If it does not have a built in DAC, the USB c adapter must have DAC to play music.

[OptimusPrime108]

I just checked on Google. Oneplus adapters don't have a DAC and your phone probably does not have inbuilt DAC. That is the issue.

Lol. It should have DAC built in. Try this.
First insert the USB adapter into phone. Start playing a music. Then plug in your 3.5 mm headphones slowly. See if at some point you can hear any audio.

Nothing happened.... Lol
