Audio stuttering - 10.14.1 Vanilla intall

Hi,

I have an audio stutter problem, that only occurs on USB audio devices, like:

- USB Bluetooth dongle > Bose Bluetooth headset connected
- USB Bose audio set
- Cheap chinese USB Soundcard

I'll try to describe the stuttering problem: When i play audio on Spotify the sound is OK, no distortion. But for every 3 seconds of playback it seems to be muted for 100 ms. So i get a stuttering effect on the music.
All of this does not happen when headphone with 3.5mm jack is connected to green port of the mobo.

I think AppleALC is installed correctly since Audio settings correctly shows all posible audio output devices.

My hardware:
Ryzen 2700X
32G Trident RGB
ASUS X470 Prime Pro mobo
RX 580 GPU

Installed kexts:

WhateverGreen.kext
VoodooTSCSync.kext
USBInjectAll.kext
SmallTreeIntel82576.kext
NullCPUPowerManagement.kext
Lilu.kext
FakeSMC.kext
AppleALC.kext
AmdCPUMonitor.kext
AHCI_3rdParty_SATA.kext
