Have u tried rebooting ur devices?

[SandeepDdn]

Have you connected any audio or any other USB device to the USB port of your mobile?

[Nissar27]

Yes bro earphone

[SandeepDdn]

Does your mobile device have a 3.5mm audio jack ?

[Nissar27]

No, only type c port for both charging and earphone

[SandeepDdn]

Although I don't have any exact solution but you can try some things and cross check:
1) Samsung Members app > Get help > Interactive checks > Headphone jack
2) Try connecting any other USB earphone to your mobile
or
Try using your earphones on another Samsung mobile and check if it is showing the same error or not.

Because your device doesn't support Revere charging and the connected USB device requires more power to run...
