Describe the bug
In the Windows Audio Mixer the PRemoteM fader keeps showing the icon of the first connection you have made with rdp instead of changing back to PRemoteM icon/Icon of another RDP session.

To Reproduce
Steps to reproduce the behavior:

1. Completly close PRemoteM (Taskbar icon -> exit)
2. Open PRemoteM
3. Open Windows Audio Mixer
4. Start an RDP Session with a saved icon. You should now see a slider called "<session name> - PRemoteM" with the icon of your connected session.
5. Disconnect session. You should now see the PRemoteM Slider called "PRemoteM" still with the icon of your previously connected RDP Session.
6. Connect to another client via RDP (best if it has some other icon). You should now see the name "<session name> - PRemoteM" but with the icon of your first rdp session.
7. Do that as much as you like but the icon of your first rdp session after opening PRemoteM stays until completely exiting the program and start it again.

Expected behavior
When changing RDP session the name AND the icon should change correspondingly.

Screenshots

Desktop (please complete the following information):

• OS: Windows 10 Pro 21H2
• PRemoteM Version 0.7.1.6

Additional context
I also think it's weird that you only get the volume fader when you start a session and not when opening the program. I mean you still have it if you close every session but it only shows when you start connecting to a client.
