Hi everyone, I am new on this forum
I search to share the sound and the USB with the RDP protocol between a computer and a virtual machine.
I want to use the Gnome Settings application but is doesn’t work.
Maybe we need a new feature and add this option.
I. Setup 
:
My pc has Debian 12 with Gnome 42 and the same on my VM. I use xfreerdp for established the connection and its work for screen share.

Critical@Critical-debian-fix:~$ loginctl show-session 2 -p Type
Type=x11
2. Virtual Machine
user@RDP:~$ loginctl show-session 2 -p Type
Type=wayland
II. XfreeRDP
I use XfreeRDP for connection. This application should work with Wayland starting from version 2.3, which can be found at Releases · FreeRDP/FreeRDP · GitHub. It should also support sound and USB sharing.
Critical@Critical-debian-fix:~$ apt show freerdp2-x11
Package: freerdp2-x11
Version: 2.10.0+dfsg1-1
Priority: optional
Section: x11
Source: freerdp2
Maintainer: Debian Remote Maintainers <debian-remote@lists.debian.org>

1. Sound / audio
I use the alsa framework and it is installed on my physical computer :
Critical@Critical-debian-fix:~$ apt show alsa-utils
Package: alsa-utils
Version: 1.2.8-1
Priority: optional
Section: sound
Maintainer: Debian ALSA Maintainers <pkg-alsa-devel@lists.alioth.debian.org>
So, when i established the connection, the screen is ok but no audio.
