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

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.
