Host audio not working after launching the guest

[ncj]

I have an issue where the host audio disappears/doesn't work after the guest is launched.

I have tried disabling the guest audio (VM setting no audio), and full audio from the VM settings, but this makes no difference. During the boot, the audio for the host disappears. I've booted with the guest extensions installed and uninstalled, both exhibit the same outcome. Host is macOS Catalina (10.15.4), Touch Bar 2018 MacBook Pro.

After the VM is shutdown, the host audio will return, but it has a slight echo at the end of any audio play, just as the audio ends it stutters.

It was first noticed by me in 6.1.2, but may have been earlier and persists in 6.1.6 and 6.0.20. Hardware diagnostics return no errors on the host.

I have reduced the RAM allocated, from 4G (50%) to 3G and the audio seems to be ok. From a thread in the forums (​https://forums.virtualbox.org/viewtopic.php?f=8&t=96902), a new guest (VDI) built from scratch seems to be ok.

I copied the VM over to a non-touch bar MacBook Pro (late 2016) and it appears to run without breaking the host audio (logs also attached).

The issue exists in v 6.1.8 as well.

I observed the same issue with macOS 10.15.7 (MaxBook Pro 2019) and VitualBox 6.1.16 (Windows 10 VM). Any chance to have a fix? This seriously limits the usability of the VM.

It is still replicated for the lastest VB and Catalina
