Nobody can tell you anything without exact system info or other technical details such as system audio settings, AE audio prefs, comp settings, exact specs of your audio and possibly the exact error message. You know, those cute numbers they come with sometimes are useful.
The code is 26 :: 392
That's...well, that's something.
Where are you getting this footage? Has it worked in previous versions of AE? Does it still work in older versions like CC 2014? Wait, what version of CC 2015 are you using?
