[MC-105155] Sound Engine looped boot during resource pack switching

When joining a server with resource packs enabled, or having a server where the resourcepack switches depending on the area of the world you are in, the client hangs for up to a minute.
Upon looking at the logs, it seems the sound engine keeps rebooting for some unknown reason. https://gist.github.com/q220/8c3b2928585bae813b8157084219f744
