[Bug]: after openal-soft bump to 1.24.2, sound stopped working in x11/luanti

[robertkirkman]

Problem description

When I uploaded luanti, the sound was working, but after fa1118b, for me the sound stopped working, and this error appeared instead:

2025-02-10 09:49:44: ERROR[Main]: Audio: Global Initialization: Failed to open device

using export ALSOFT_LOGLEVEL=3 can show slightly more information:

I completely do not understand why mplayer -ao openal, mpd, and mpv --ao=openal continue to work with this version of openal-soft while luanti does not, and I have been unable to find any way to patch luanti to work with the current openal-soft package, which is very confusing since luanti calls alcOpenDevice() in an almost completely identical way to how mplayer calls it. I cannot tell what the difference is, and all changes I have attempted to luanti's alcOpenDevice() call have had no effect (for example I tried refactoring out the references to unique_ptr_alcdevice in such a way that the sound continued to work with openal-soft 1.24.1, but it still did not work with 1.24.2).

https://github.com/luanti-org/luanti/blob/dd0070a6b8a28e2fe2ac591b3ea96813ba9ffcb0/src/client/sound/sound_singleton.cpp#L15

The only One of two ways I have found to work around this is to revert the two commits in openal-soft 1.24.2 that I bisected this problem to.

kcat/openal-soft@8767fdd
kcat/openal-soft@e359dbf

the other way to work around the problem is to add export LDFLAGS+=" -Wl,--no-as-needed,-lOpenSLES,--as-needed" to the build.sh of luanti or any other packages that might be found to exhibit the same problem in the future.

What steps will reproduce the bug?

pkg install x11-repo
pkg install termux-x11-nightly xfce luanti
export DISPLAY=:0 TERMUX_X11_XSTARTUP=xfce4-session
termux-x11 &
luanti

What is the expected behavior?
