%%%Crash happens with both OpenAL and SDL with 64bit build. I noticed that very short scrubs and clicking in strip doesn't crash blender immediately, but will at some point.

For both OpenAL and SDL no crashes happen when caching is enabled for the strip.

I don't have a debug build (and currently no time for doing deeper investigation - perhaps Thomas Dinges can help here out), but the (incomplete) backtrace I see is:

Possibly a problem with threading and reading from disk.

%%%Confirmed the crash on windows x64 as well with OpenAL and SDL.
x32 builds are fine, can't make a debug build though, the exe does abort with an error while starting already. :/ %%%

%%%As discussed in chat:

Problem arises with libsndfile and ffmpeg only on windows 64, without any appearance of a blender code caused reason, so unfortunately nothing we can do here.

Workaround: In case you need scrubbing, cache the sounds, works better then anyway.%%%
