No Sound From Speaker After Water Spliige

@jimessex we will need to know the exact model number of this laptop. Acer Aspire 3 is a series that describes more than one model. Bottom line for now is that you will need to get to the motherboard. Then remove that as well as any other board. Check those boards for corrosion. In particular around the speaker connector, the headphone jack as well as the audio IC. As you can tell, we will need to see your motherboard and need to know what exact model that is as well. That way, we can try and see if schematics are available which will be helpful to determine where the water may have shorted your audio system.

Use this guide to add images of your motherboard etc. Adding images to an existing question The more we see (well focused and large enough of course) the better.

After you have remove the motherboard (and possibly others, depending on the model), the next thing to do is to clean it. You must remove all EMI shields from the boards. If you do not remove those, you might as well not do anything. After you removed those, clean the whole board, connectors and all with +90% isopropyl alcohol. Follow this guide, and even so it was written for an iPhone all the points are still pertinent to your computer as well. While you clean your board, check for any obvious damage, like burned or missing components etc. All these steps are to avoid delayed failure caused by corrosion. Best thing to do would be to clean it with an ultrasonic cleaner, but if you do not have access to one, this will at least help. When it is properly cleaned, reassemble your laptop and reevaluate.
