Right speaker works 100% while left side sounds like 50% or even less

[EcNoD_LTU]

Just opened my new laptop HP Spectre x360 15-df0002na 4K UHD few minutes ago. 
I noticed that right side speaker plays much louder then left side.
So i went to sound settings( Speaker/Headphones properties)>Levels>Balance. Both Left and Right sides were the same.

Dont know what to do next, dont want to send it back for repair after its been unboxed 30 minutes ago.
