[Error] Virt-Manager in rootfull+init dbox "crashes" sound for other apps

[nunix]

Describe the bug
When starting virt-manager from a rootfull+init dbox, the USB audio devices are no more accessible from other apps, such as Chrome or Brave browsers (installed as flatpak).

To Reproduce

• Create a new rootfull+init dbox:

distrobox create --name virt --root --init

• Install virt-manager and dependencies:

sudo zypper in +pattern:kvm_server +pattern:kvm_tools qemu-spice virtiofsd qemu-hw-display-virtio-gpu
sudo usermod -aG kvm,libvirt $USER
# [Optional] export the desktop app
distrobox-export --app virt-manager

• Create a test VM with all the defaults (it doesn´t need to be started aftwerards)
• Exit dbox and stop it:

exit
distrobox stop --root virt

• Start a web app that requires sound (i.e. meet.google.com)
• Open virt-manager (from the desktop icon if exported, or from the CLI inside the dbox)

RESULTS: the running app (i.e. meet.google.com) has no more access to sound devices.

Expected behavior
The sound devices should remain available to the running apps.

Logs
N/A and specific logs can be provided on-demand.

Desktop (please complete the following information):

• Are you using podman, docker or lilipod? Podman
• Which version or podman, docker or lilipod? 5.0.3
• Which version of distrobox? 1.7.2.1
• Which host distribution? Aeon
• How did you install distrobox? installed by default

Additional context
I have a workaround: my audio devices are all USB, and if I remove the USB redirection from the VMs configuration, I don't have this issue.
