my audio works great with other applications, and speaker-test is ok. I think that the problem is due to the interaction between unreal engine and Pulseaudio.
I found this in pulse audio log:
[pulseaudio 2700]: Error opening PCM device hw:0: Device or resource busy
I’ve got this error only when I run my unreal app, not with other apps.
And I’ve got this problem only on ARM, not on linux x64
I’ve tried different boards (raspberry pi4 and banana pi m5) and different os (raspbian, Arabian, ubuntu mate)
is there any way to make unreal engine interact directly with ALSA without using pulseaudio?
