I've recently updated my Unity integration to Wwise 2015.1.7. It work fine in the editor, but no sound in the build. The log informed me that soundbanks are not where they supposed to be. I checked, they were there, as usual.
Added more logging and realized that ms_Instance.basePath doesn't contain the path set in the WwiseSettings.xlm (which is set to Soundbanks folder under StreamingAssets). The Init.bnk path building sequence looks as this:
ms_Instance.basePath: 3533366637353665363434323631366536623733
fullBasePath: [...]/StreamingAssets\3533366637353665363434323631366536623733
InitBankPath: [...]\StreamingAssets\3533366637353665363434323631366536623733\Windows\Init.bnk
I fixed this for now by hardcoding Soundbanks in basePath, but I have no idea why it is set to such value.
My WwiseSettings.xlm:
?xml version="1.0" encoding="utf-8"?>
<WwiseSettings xmlns:xsi="

<CreateWwiseGlobal>true</CreateWwiseGlobal>
<CreateWwiseListener>false</CreateWwiseListener>
<OldProject>false</OldProject>
</WwiseSettings>
