Unreal Engine 4.15 integration "IO Device error" and "Bank Load Failed"

0 投票

We are encountering the following problem at the moment (using Unreal Engine 4.15.1 and the latest integration):

Some sound banks (not always the same ones, also not dependent upon size it seems) fail to load with the following messages:

LogAkAudio:Error: IO device error
LogAkAudio:Error: Bank Load Failed

In a development build, this lead to the sounds simply not working. A shipping build even crashes with the following log:

What we tried so far:

  • Regenerating sound banks
  • Decreasing sound bank size (thinking it was a memory problem)
  • Disabling async loading
  • Increasing the default pool size for sound banks

We would be very grateful for any hints on how to proceed with this problem.

We are seeing a crash with "Event Driven Loading" enabled, have you tried disabling that?

Thanks a lot, this was in fact the solution for us. It seems like Epic has already seen errors with the system since they disable it in the 4.15.2 hotfix by default.
