AL lib: (EE) alc_cleanup: 1 device not closed error


Recommended Posts

When I run my code, minecraft opens and does fine until I open a world. Then I get this error log:

A detailed walkthrough of the error, its code path and all known details is as follows:

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.
