Our Unity title has Wwise audio working 100% correctly on all platforms except Linux. (i.e. Windows/Mac/Consoles). After starting up the game, we see the expected events fire in the Wwise profiler but no audio is heard,. Our log is showing the following:
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
AK Error: Unknown game object ID. Make sure the game object is registered before using it and do not use it once it was unregistered.

AudioManager: Using PulseAudio: Default Output Device
(This all occurs BEFORE our first Game Object is even started/running which actually initializes Wwise)
The same generated banks and code is working perfectly fine for our Windows/Mac builds; what could cause this? We are using the 2015.1.4 integration. (Strangely, some streaming music played later in the game IS HEARD without issue, so it seems that the Wwise engine has at least properly initialized, just cannot play audio from the banks.)
