PS5 audio freeze

Unreal Engine
1

Hi,
UE 4.27plus latest from Epic’s Github. Sony SDK 7.0 FMOD 2.02.14
Whan launching game on PS5 after loading audio banks our logs are spammed with this message:

[2023.07.14-08.04.16:148][  0]LogAudio: Warning:
00:12:58    Dump of call to sceAudioOut2PortSetAttributes:

00:12:58            
00:12:58        Result: SCE_AUDIO_OUT2_ERROR_INVALID_PARAM

This is causing title to freeze.

In Ps5Engine.ini I have:

[Audio]
AudioDeviceModuleName=
AudioMixerModuleName=
AudioDeviceModuleName=Ngs2
; Defining below allows switching to audio mixer using -audiomixer commandline
AudioMixerModuleName=PS5AudioFeatures
UseAudioMixer=true

What am I missing?

Have a great day :slight_smile:

Hi,

The issue is FMOD won’t work with built-in UE audio without engine modification (Unreal Integration | Platform Specifics - PS5). In your PS5Engine.ini you are both disabling and setting the AudioDeviceModule and Mixer. There is a linked forum post here: which outlines the modifications required to get FMOD to work with UE audio: https://qa.fmod.com/t/unreal-video-playback-with-audio-on-ps5/16555/2.

Another solution is just disabling UE audio altogether.

Hope this helps.
