I have just received my Huawei P20 Pro, the volume using wired audio devices is quieter than I would like. I have looked online for a fix and have found that it is software related and can be fixed in a software update. i have also found that other Huawei and those of sister company Honor device users are also having this issue. 

I am currently in talks with Huawei about this getting resolved without the need to root our phones!

here are forum links to reports (and some the fixes):
