The sounds sound like static

Could not duplicate this, it seems to be only on your system. Have you tried reinstalling Minecraft?

I have the same problem and it remained after reinstalling. Do the other people with this problem also run OSX 1.5.8 or older, and the older version of java that goes with it?

I have the exact same problem. I have a non Intel based Power PC Mac. All the sounds sound like static. We used to have this issue for 10.5.8 macs before but it was solved. It seems to have returned.

I have the same problem. I too am using an Power PC Mac. OSX 10.4.11. This is my first really annoying problem. I reinstalled and go the same result.

I got to a Max osx 1.5.8 powerpc n i hear to only weird sounds.they really need to fix that

Is there anyway we could make this a more than minor issue? I know I have an old computer but playing the game without sound makes playing in hardcore really difficult. a.k.a. Creepers boom.

So. The common issue is that you all have ancient PPC based systems. Apple dropped support for them quite some time ago (you cannot update to 10.6+). People who build bindings for OpenGL/OpenAL hardly ever give any priority to get compatibility with PowerPC-based systems and this makes it impossible for us to support it beyond a 'best effort basis'. Which in this case is: it works? good; it doesn't .. well ... :'(

There appears to be a solution.

I tried it on my system just now and it works.

You only have to replace the JOrbis CODEC. Then it will work.

Invalid because not a Minecrat bug.
