I ran in to similar issues.  I came across this: 
https://twosortoftechguys.wordpress.com/2018/07/24/make-lirc-work-in-ubuntu-18-04/ 
.  The issue being lirc in 18.04 has issues and downgrading lirc fixes them.

It's very helpful if you keep all your /etc/lirc files and the remotes/ 
files from your previous working install to copy back over.
