Had an issue where various games were crashing when started, these included: Trine, Penumbra 1 & 2, Hacker Evolution: Untold, and several others.
Errors included an array of things such as “couldn’t load library X”, segmentation faults, etc (sorry, I didn’t record all the errors before fixing my problem!). Most of the searches on these errors pointed to missing 32-bit compatibility libraries, but for me, that was not the case.
Since I had a lot of issues in 11.4 with pulseaudio, and the errors seemed to be hinting at an audio problem, I figured I’d remove it and see what happened. Sure enough, all the games now start without issue. I even see some options in my mixer that were previously missing/hidden by pulseaudio.
