AAC not working on iOS 11 after switching to v2016.2.4 build 6098

Question

I had been using Wwise 2015.1.65, which worked OK under iOS 11 although there were some issues. My AAC sounds played fine.

I just updated to v2016.2.4 build 6098, and now my AAC sounds don't play at all on an iOS 11 device

AK Error: AAC decoder failure: 205100711

AK Error: Failed creating source: 205100711

I no longer have an explicit codec registration (I do include <AK/Plugin/AkAACFactory.h>), but was hearing AAC sounds just fine on an iOS 9 device. And non-compressed sounds are OK on both.

Is this a known issue? Did I miss some trick in migrating?

Comments

I got my sound designer to re-export in Vorbis format, and that works on iOS 11 beta. (But it sounds terrible in the iOS Simulator, plus AAC can use hardware to decode.)

Hi David,

Upgrading to Wwise 2017.1.3 should solve your problem. There is a fix for this specific issue in this release.

Thank you!

Great! But won’t I have to go back to my sound designer and get him to update his Wwise (to match this version) and then re-export as AAC? He has moved on to other projects…
