So I monitored the Device Output log from a Dev Build running on iPhone 6 and the log throws this every time the audio glitches:
May 27 12:26:14 Wards-iPhone DubBoxingv1[684] <Notice>: [UE4] [2020.05.27-19.26.14:306][446]LogAudioMixer: Display: Audio Buffer Underrun detected.
There are tons of them, as stated earlier it gets worse over time. They grow one every few seconds whether anything is happening in game or not (beyond background music). They are in game regardless of buffer size settings (512/1024/2048 seem to make little to no difference). “Number of Buffers To Enque” is 1 from what I just tested but the problem is there with 2 also. Source Workers settings is kept at 0. Test was done with sample rate at 44100 but builds with sample rate at 22,050 had same problem. Any quick ideas I am over looking? I can provide full log if need be.
Thanks
