Hello Thelma the first of those errrors gives me a link Dell Diagnostics Audio Tests - Audio - Laptop - Dell Community that sorta explains things a bit.
Now if it were me I would (if it is the inbuilt speakers) get a small inexpensive USB connect speaker system.
If you are running short of USB outlets then you may need to run a powered USB hub - both of these are really not expensive and frankly the quality of the audio will be so much better than the machine ones.
