      Workaround

      If you experience this bug, you can press F3+T while ingame to reload the sound engine, which should fix it temporarily.

      If the bug persists for an extended period of time, you should instead contact 💬 Community Support as it is likely a driver issue or another configuration issue on your end.

      Occasionally when resources are loaded, OpenAL fails to start and there is no sound. Generally it works fine, but very rarely it fails.
      In that case, it switches to no-sound version.
      This is a game log from when it failed to start:

      Note that the 3 failures after each instance of "getPathFromClassLoader: searching for:" happen even when audio works successfully - it's likely a platform thing. Additionally, "Could not locate symbol" at the bottom also occurs each time. Finally, note that C:\Users\Pokechu22\AppData\Roaming\.minecraft\OpenAL64.dll does not exist and never should exist (as it is only supposed to be located in the temporary natives folder) - the "Could not load OpenAL library" message from it probably is a red herring; the earlier "Could not open ALC device" and "MMDevApiOpenPlayback: Device init failed: 0x80004005" are probably more useful. Also, note that 0x80004005 is a meaningless error code; it just represents E_FAIL which means "Unspecified failure".

      After asking the OpenAL mailing list for additional information, it turns out that this is a fairly old OpenAL bug, which was fixed in OpenAL Soft version 1.16. Minecraft is using version 1.15.1 (as LWJGL 2 uses it). This can be fixed by updating OpenAL, either by migrating to LWJGL 3, or just directly updating the OpenAL dll using the one from LWJGL 3 on LWJGL 2.

      I would suggest having Minecraft detect when this happens, and try to restart OpenAL. If it fails multiple times, then it should force a no sound mode. At minimum, a message should be displayed on the title screen in some way, advising the user to use F3+T to reload the sound engine.

      MC does attempt to detect this happening in SoundManager, but the sound is loaded in a separate thread from which the catch statement happens. Thread.setUncaughtExceptionHandler should be used instead. Even then, that handler only logs an error and mutes audio; for the general user this behavior isn't entirely obvious ("Why did my game just mute itself‽") although (IIRC) doing that does reload the sound engine when it's unmuted.

      MC also has a custom SoundSystemLogger (also declared in SoundManager); that could be used to identify such errors as well.
