Custom sounds not work after 0.27 update (Fixed in Hotfix 0.27.1)

Hi
I would like to know if there any change in sound files that I need to change in my mods?
it work on 0.26 but now it just didn't.
the red truck is in 0.26 version and black is 0.27

 

I found this fix in the 0.27 discussion thread. I can confirm that it works, but be warned, it makes the sounds extremely loud.

 

Yes thanks now it's working
I don't find it louder but also can only down the volume if necessary
