Description Grósz Dániel 2021-08-21 02:39:59 UTC 
After updating Tumbleweed to 20210817, containing libSDL2-2_0-0 2.0.16-1.1, there is no sound in the game Xonotic when started with the xonotic-sdl command. Xonotic doesn't even show up as a Pulseaudio client application at all. (I use KDE Plasma on X.org. The xonotic version is 0.8.2-6.1, not changed recently.)

When starting Xonotic with the xonotic-glx command, sound works. (There are a few differences between using the sdl and the glx version, such as mouse acceleration.) I don't know if there are other SDL applications affected; I've tried notpacman (a game that uses the Löve (love) engine, which depends on libSDL2-2.0.so.0()(64bit)) and it has sound.

If I downgrade to libSDL2-2_0-0 2 2.0.14-1.8, from Tumbleweed 20210810, xonotic-sdl has sound again.

This has been reported on the mailing0list with a workaround:

SDL2 does strict checking of the module name, something it only did 
*very* loosely previously (commit 
25f9ed87ff6947d9576fc9d79dee0784e638ac58).

The problem is in the pulseaudio RPM which:

/etc/profile.d/pulseaudio.sh:export SDL_AUDIODRIVER=pulse
/etc/profile.d/pulseaudio.csh:setenv SDL_AUDIODRIVER pulse

A cursory play-around-a-bit tells me this should be 
"pulseaudio", not "pulse".

Fix is already pending.
