Virtualbox 6.0 sound issues

[StuardBr]

Hello!!

I was using VirtualBox 5.2.18 with an Ubuntu 18.04 guest without any problems, so, today i updated to the 5.2.28 and started to suffer issues in the audio. So, i searched and founded that this wasn't the newest version and updated again to the 6.0.6 and the problem persist. I can try to rollback to the 5.2.18 but first I want to know if there is something i can do to keep this version and solve this problems.

Sometimes the problem happen in 5 minutes of continuous playing, sometimes after 15 minutes, sometimes after 3 minutes...

Host: Dell Optiplex 9020 - Intel Core i7 4790 @3,6 GHz - 16 Gb RAM

Guest: Ubuntu 18.04 - 2 CPU - 8 GB RAM
PAE/NX Enabled
3D Enabled
128MB Video memory
Guest Additions installed

How to reproduce:
Audio streaming in spotify
Youtube
VLC playing audio

Tried some tests:
- Windows 10 1809 guest - Impossible to test, after some minutes of playing the VM crash (Log attached)
- Changed the audio driver in the VM settings to Intel HD Audio: Nothing
- Instaled Pulse Audio Manager in the Ubuntu and changed profile: Nothing
- Tried in Google Chrome (Version 74.0.3729.131), Mozilla Firefox (66.0.3) and VLC.
- If I open the audio settings window of the guest system while listening something, the audio just freeze.

PS: Logs bigger than 128 KiB, so, i put in the pastebin. I needed to change the U RL because i can't post U RLs yet, so sorry about this.
