Without those data files HRTF will silently fail to initialize. It searches /usr and /usr/local by default but we don't have those paths. It also searches XDG_DATA_DIRS but using that requires configuration by the user. This patch makes makes it just work. How to play with it: - Build `mpv` with `openalSoft` support. - cat << EOF > ~/.alsoftrc [general] hrtf = true EOF - Wear stereo headphones. - Play a file with 6 or more channels with `mpv -ao openal $file`, e.g. https://archive.org/download/5.1SurroundSoundTestFilesVariousFormatsAACAC3MP4DTSWAV/5.1%20Surround%20Sound%20AAC%20Test.mp4 - Try `hrtf = false` to hear the difference.
