MacBook Pro Intel i7

Excellent condition MacBook Pro (2017 model) still functioning perfectly except for the internal sound which has stopped working for some reason. However, this can be worked around by using an external speaker/headphones connected by bluetooth or USB-C or even a dock i.e. an external sound device. There's a slight ding on the top left of the lid (screen) as shown in the photo, but this is purely aesthetic, no impact on the screen or function of the laptop. This happened about a month after I bought the laptop brand new in 2018 and nothing to do with the sound.
