"AL lib" Warnings

Of late, I’ve been seeing a new set of warnings pop up when I run Panda applications. It doesn’t seem to be causing any trouble that I’ve thus far detected, but it does seem to be remarkably consistent–even popping up in extremely simply applications.

The warnings are as follows:

AL lib: (EE) GetLoadedHrtf: Invalid header in /usr/share/openal/hrtf/Default HRTF.mhr: "MinPHR03"
AL lib: (EE) GetLoadedHrtf: Failed to load /usr/share/openal/hrtf/Default HRTF.mhr

To start with, I just want to bring the appearance of these to light.

And secondly, I want to ask whether any changes are called for on my end–a new version of AL lib, or something like that, perhaps.
