Hi!
Since last update (1.8.1), I have no sound at all in Minecraft.
I get "missing pack.mcmeta" in the resource pack menu, under the default resource pack. Error messages also show up in the launcher under the "Game Output" tab. e. g. "[15:51:37] [Client thread/WARN]: Unable to play unknown soundEvent: minecraft:gui.button.press".
So far I've tried: Deleting all Minecraft files and reinstalling everything, same with Java (both 32 and 64 bits were tried, separately and together), running an earlier version, using the F3 + S shortcut ingame, playing in fullscreeen vs windowed, deleting and reinstalling openAL32.dll and openAL64.dll
All sound hardware and software work flawlessly on my computer, I get sound from all other programs and Minecraft isn't muted in the Mixer neither. Also, I don't have any mods/resource packs installed.
Thanks a lot for your time!
Please attach the complete output of the "Launcher Log" which can be found on the second tab of the launcher.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".
