I installed modloader and after forge client into my minecraft.jar, deleting META.INF too. My game runs and mods are working, but I have a seriously problem: I have no sound, my music and sound turns to 0% when I install forge and when I try to change it crahes my game, my game screen turns black and for only less than 0.5 sec I see the error log, so I can't copy it, but in my minecraft folder generates ForgeModLoader.log file that show me the error. And it's not caused by other mod because my minecraft.jar was clear when I installed forge, and without mod the eror still happen. Can someone from forge help me please to fix the sound crash problem?
Versions of forge I tried minecraftforge-client-3.3.8.164 and minecraftforge-client-3.3.7.135 and MinecraftForge-3.3.8.152-Client
My computer is Mac OS X Lion, with Java 64-bit, 2,4 GHz Intel Core 2 Duo, ATI Radeon HD 2400 XT 128 MB, 3Gb RAM.
