I have an HDA-Intel PCH sound card and details of my sound configuration from running the alsa info script is here:

On Opensuse 13.1 XFCE I find that I cannot control the current playback device using the default xfce4-mixer application launched from the default volume controller menu. In Gnome or Kmix for example (and pavucontrol), you can switch between different playback device options like analog stereo output, and HDMI stereo/5.1 digital surround. The only reference to the HDMI audio device in the xfce mixer is I think IEC958 which can be seen by enablling "switches" from the "select controls" options. Unchecking IEC958 turns HDMI sound off.

If I install pavucontrol I can switch playback device configuration by selecting from a number of profiles like analog stereo or Digital Surround 5.1 (HDMI) outputs. Screenshot here:

I wanted to ask if it is possible to make the default xfce4-mixer (accessible via the system tray volume control icon) to show a subdevice menu so I can switch between different audio output devices without having to resort to pavucontrol. I know it can be done as when I had installed XFCE on an Opensuse KDE installation and booted into the XFCE DE I could switch between HDMI and analog stereo via the volume control mixer (can't remember accurately but I think I could do this as the HDMI and analog subdevice opitons appeared as separate cards where there is now just one sound card (HDA Intel PCH) in the mixer window (see first screenshot) in the XFCE only OpenSUSE installation.

Here is the aplay -l output if it may help:
siva@JAC2:/tmp> aplay -l
**** List of PLAYBACK Hardware Devices ****

Any kind of help here is much appreciated.
