Speakers output buzzing sound since 4.15

I could really use some guidance on an issue I've been having with sound on booting Arch.  This problem only emerged after the kernel upgraded to 4.15.  Before that, for the last two years I've been using this NUC6CAYH this problem never occurred, so I think this is a kernel related issue.
Basically, about halfway through the booting process before the login screen appears the speakers come on and produce a loud and annoying buzzing noise.  This noise continues even after logging in.  Starting pavucontrol stops it and restores silence.  At the moment my workaround has been to autostart pavucontrol but I'd prefer to get to the source of this problem and eliminate it. 
Any help will be much appreciated.
