Hey guys, there is some update to my issue. It has not been resolved in 4.25 Preview, so I started thinking that something is wrong with my computer.
I did not pay a lot of attention to my logs and that was wrong.
I found out that there is some problem with my audio device:
LogAudioMixer: Warning: Audio device removed, falling back to other windows default device.
LogTemp: Resetting audio stream to device id
LogAudioMixer: Display: 0: FrontLeft
LogAudioMixer: Display: 1: FrontRight
Every time a spike happens I get this warning.
I don’t know what the problem is with my speakers. They seem to work fine. I watch videos, listen to music. Even in UE audio works fine. More importantly in UE 4.22 there were no such warnings.
But anyway, now I get these warnings. If I unplug the speakers, the warnings go away, and the performance spikes never happen again.
I tried to update audio drives but nothing seems to help me.
Any ideas?
p.s. BTW, the warning gets logged in AudioMixerPlatformWindows.cpp on the line 315 (method FMixerPlatformXAudio2::OnDeviceRemoved)
