Macbook Air A2337 820-02016-07 No sound problem

How about everyone, I have a MacBook Air which did not turn on, it had a lot of corrosion on the card where the sound plug and the fingerprint go, I have replaced it and the device now turns on but has no sound, if I connect a headphone through the plug, yes There is sound but the external speakers do not sound.

Often this fault is from the headphone connector itself. Try blowing out the jack with compressed air to clean it out. If you disconnect the headphones, does the OS report that speakers are active?

In fact, I changed the entire piece since the original one it came with was reaching very high temperatures... I already tried to clean it and I still have no sound from the speakers.
