Years ago I set up Travis to notify my GH pull requests of CI pass/failure but some time in the last year this stopped working. I have searched the documentation but was not able to find anything to sort this out.
An example of a project I am having this problem with is https://travis-ci.org/github/erikd/libsamplerate/ .
I have added a PR for testing travis/github integration: https://github.com/erikd/libsamplerate/pull/104 . The travis build is happening here https://travis-ci.org/github/erikd/libsamplerate/builds/705012242 .
