Hi @alferdtenneson
Insert a set of headphones into the laptop and check if audio is heard in both headphone speakers. This is just to verify that the audio codec IC is working OK.
It the audio is OK when using headphones, here's the [https://dl.dell.com/content/manual17912857-dell-latitude-7390-owner-s-manual.pdf?language=en-us|owner manual] that will help.
Go to p.21 to view the procedure to remove/replace the speakers. The speakers come as a module consisting of a left and right speaker as they are both connected to the one plug that is connected to the motherboard.
Search online for ''PVYM2'' to find suppliers that suit you best.
