Short Noise On Level Start

In my project there is a short noise (just few ms) when a level loads (actually since it is so short i cant tell exactly when i happens: when the level is loading or when finished loading…).

few facts:

  • the sound occurs every now and then. pretty erratic.
  • i use the latest version of unity since few days.
  • the sound occurs mainly on ipads (retina and mini) but i think it happened in the editor few times too.
  • changing the length of the audiobuffer changes the sound but it does not make it dissappear.
  • it sometimes happens before i do anything with sound

i have no idea how to track this problem down and would be thankful for any advice.

ok, it seems to be an issue with unity 4.2.1. i just imported an older version made with 3.6 into the 4.2.1 one and the noise is there.
and now i’m positive it’s not an iOS thing. it happens in the editor too. so i suppose that updating Xcode would not help either. i’m i right?

has anyone the same issue?

the noise is still there…
