Minecraft – No sound in Minecraft

Let's look at what is happening: Minecraft is trying to do something which returns 0xc0000005.

In ntstatus.h, a list of error code definitions, 0xc0000005 is STATUS_ACCESS_VIOLATION.

MSDN - Analyze Crashes to Find Security Vulnerabilities in Your Apps reports:

Access violation exceptions (STATUS_ACCESS_VIOLATION) are generated by modern processors when a memory access caused by an instruction or program execution does not satisfy certain conditions defined by the processor architecture or memory management unit structures.

So, we now know that Minecraft does something that causes invalid memory access.

But, what exactly is Minecraft doing?

j  org.lwjgl.opengl.WindowsContextImplementation.nCreate(Ljava/nio/ByteBuffer;Ljava/nio/IntBuffer;Ljava/nio/ByteBuffer;)Ljava/nio/ByteBuffer;+0
j  org.lwjgl.opengl.WindowsContextImplementation.create(Lorg/lwjgl/opengl/PeerInfo;Ljava/nio/IntBuffer;Ljava/nio/ByteBuffer;)Ljava/nio/ByteBuffer;+10
j  org.lwjgl.opengl.Context.<init>(Lorg/lwjgl/opengl/PeerInfo;Lorg/lwjgl/opengl/ContextAttribs;Lorg/lwjgl/opengl/Context;)V+104
j  org.lwjgl.opengl.Display.create(Lorg/lwjgl/opengl/PixelFormat;Lorg/lwjgl/opengl/Drawable;Lorg/lwjgl/opengl/ContextAttribs;)V+88

Here we see, Minecraft tries to allocate an OpenGL Device Context buffer in memory.

The thread mentioned by Ben Blank has a different stack trace and thus is irrelevant.

We first have to get more knowledge about your memory, which you gave:

I noticed that the command that the minecraft.jar file is being run with says that it can have up to 1024mb of ram. I only have ~500mb of ram, so it would be referencing pointers in an unknown location. I also notice a gl issue, which I'm not really sure how to fix.

Given that low amount of memory, I'm going to guess that your graphics card uses 128 MB shared memory which means that it uses RAM memory to operate. I'm guessing that your Windows uses another 100 MB. There is only 250 MB of memory remaining for Minecraft, and your page file.

Minecraft uses from 512 MB to 1 GB, consider that playing Minecraft will cause disk trashing.

VM Arguments:
jvm_args: -Xms512m -Xmx1024m 

So, now, where does the problem lie?

"so it would be referencing pointers in an unknown location" -- no. Just because you tell it it's allowed to use 1024 MB doesn't mean it ignores allocation errors when it runs out of space and creates invalid addresses out of thin air to reference. For all I know it wouldn't even matter, Windows would just give it space in the page file. - Matthew Read

This comment on the question is not 100% correct, there are exceptions that don't use the page file.

Exactly, OpenGL Device Context buffers must be in RAM; the solution is to buy more RAM.

I doubt if 1 GB will do the job given that Minecraft can use up to 1 GB; better to be safe than sorry and get 2 GB to avoid future problems. This also makes sure you don't experience disk trashing to the page file, which can have a great impact on the performance...

Or well, I could be all wrong and it could be a driver problem. But seriously, 512 MB isn't enough...

Yes, you are able to play custom sounds with Command Blocks using command:

playsound <sound> <player> [x] [y] [z] [Volume] [Pitch] [minimumVolume]

Minecraft Wiki has the following description:

Example: Sound located at .minecraft\assets\sound\mob\pig\death.ogg The value for sound would be written as mob.pig.death, as the command originates from the sound folder. For sequentially numbered files pertaining to the same event (like various walking sounds), the player must exclude the number of the sound (for example, sound located at .minecraft\assets\sound\mob\pig\say2.ogg). In this case, the command will play a randomly selected sound out of the three available. A player or area must be selected, and the player must be able to hear the sound from where it is played.

I have no knowledge on adding more numbered sounds, but the wording of the above description makes me think it should be handled OK by the game. Unless anyone else adds that information, you'll have to test yourself - just add a loud scream to zombie groans and walk around for some time :)
