You can make this a lot easier by adding 'PulseAudio Volume Control' to your audio-VM in the Applications-settings.
#### Installing `pasystray`
To recover some tray-icon functionality, install the package `pasystray` in the audiovm's template:
```sudo dnf install pasystray```
It won't provide all functions the dom0 tray-icon provided. To autostart the tray-icon on audiovm boot, add this line to `/rw/config/rc.local` in your audiovm:
```pasystray```
The tray-icon should provide:
* volume-indication
* change volume via mouse-wheel
* open `pavucontrol` (Volume Control GUI) via menu
The `pasystray`-project reports other functionality as well, though they don't seem to work seamlessly in QubesOS.
### Getting Keyboard-Control For Volume
Since the keyboard is attached to dom0, you need to build a solution in dom0. The approach chosen is to run a command in the audio-VM and bind those to shortcuts in xfce.
