1. Audio issues. When using PulseAudio driver in guets, VirtualBox

somehow changing other Guests volume affects other one.
I don't remember significant audio changes in quite a while. Are you
sure that this is new in 6.1.97 (which is a dev version of what will be
released in the unknown future) and does not happen in 6.1?
Also, you'd need to describe in a lot more detail what "using PulseAudio
driver in guests" means. Which Linux distro, which audio config in the
VM, all config details, VBox.log and so on. Otherwise we can't say much
intelligent.
Or are you talking about using PulseAudio on the host (yeah, the driver
is selected in the VM config, but it will not be used as such by the
guest since that can be any OS)?
Host is Arch Linux with custom built kernel (for kdump functionality and
ISA bus enabled for ISA soundcard (Sound Blaster 16) in the VirtualBox)
5.7.18. One Guest is Windows Server 2008 R2 SP1 and other have Arch
Linux (same custom built kernel as in the host) as its OS.
PulseAudio on the host (and in the Arch Linux guest) and "Host Audio
Driver : PulseAudio" selected in the guest settings. Yes, that happens
only 6.1.97 starting with r139689. 6.1.97 r139475 was working fine. And
VirtualBox 6.1.13 r140124 (Qt5.6.1) is working fine, too.
2. Taking a snapshot aborts running guest. This happened to Windows
Guest of mine. Attached two files which one is output from "coredumpctl
info" and the log file of the guest (VBox.log)
This could be anything... from the stack traces it's some sort of heap
corruption (from the looks detected straight after a new thread was
started). Not something we're seeing ourselves so far.
VBox.log is always useful (even though if this case it doesn't
correspond to the crash you mentioned, because it's a successful VM run
which takes about 14 seconds, ending with a poweroff). It shows that
you're using a rather unsuspecting VM config.

Hmm, alright.
