Help with sound on the modpack!

[JMLG]

Today I tried to enter the new version of Tekkit (1.2.7b) and when I entered the game, I had no sound at all! Not even the sound of the *clicks*!

 

But I noticed that on the Console there's this:

 2014-03-04 12:00:03 [iNFO] [Minecraft-Client] LWJGL Version: 2.9.0

Can someone help me with this thing?

I have that issue if I start the game before I plug in my headphones. restart the game and sound should return (if your using headphones)

Already tried that, and updating LWJGL and OpenAL32!

It's soo rage making*!

I only ever had the no sound problem if I ran Attack of the B-team offline. Strangely enough I could hear the waterfall sound as the only sound? (if near waterfalls)

 

Closing the game and the launcher, connecting my computer to the modem and starting the launcher again in online mode gets me sound again.

 

This only ever happens on AotBt, I tried Hexxit offline and it had sound.

does the vanilla minecraft have sound? as in the mojang launcher version not the tekkit launcher version

I am presuming you have checked the ingame sound volume?
