[MC-489] No sound when starting Minecraft

When I start Minecraft I can't listen anything, but 1 or 2 minutes later Minecraft runs normally.

Environment

This can happen while Minecraft is downloading the resource files the first time.

Does this happen every time you start Minecraft, even after you have loaded a world?

This happen fisrt time I load a world

Does it happen every time on every world you load?

No, only with the fisrt world

Working as intended.
