Strange, that OGG file is also playing fine on an RPi here (testing with the examples in the BASS package), in both armhf/hardfp and aarch64 flavours. Are you able to reproduce the problem yourself? If so, please try upgrading to BASS 2.4.17, and if that doesn't help then also try one of the BASS examples for comparison. If the BASS example is working, you can then compare its code with yours to hopefully find what's causing the problem.
