Windows 10: Monitor Audio speakers disappears when closing lid.

I've got the following system:
- Microsoft Surface Laptop 2 (I7 / 16GB / 512GB)
- Microsoft Surface Docking Station
- Asus MX25AQ Monitor connected to Docking Station via Displayport
- Logitech keyboard connected to Docking Station via USB
- Logitech mouse connected to Docking Station via USB
- LAN connected to Docking Station

If I start the laptop with lid open everything works fine.
Microsoft finds both realtek HD speaker on Laptop and MX25AQ monitor speakers and I can switch speakers from notebook to monitor and back using the volume icon.
When I close the laptop lid the screen I can see the monitor in full resolution, but MX25AQ audio disappears and I can only hear sound from the laptop.
If I open the lid again it is still gone.
For audio on MX25AQ monitor to work I need to restart windows with laptop lid closed.


Is there an option that when I close the lid of the laptop audio will switch to the MX25AQ monitor or at least not remove the MX25AQ option from volume icon ?

HDMI Audio disables itself when lid is closed

HDMI Audio for some reason decides to disable itself when the lid is closed. i have it connected to my TV with an HDMI cable. when the lid is OPEN, audio is routed to the TV as its supposed to be. but when i close the lid, it forces the audio to switch back
to the internal speakers, with NO WAY AT ALL to switch back without reopening the lid. is there a setting for this? it is incredibly annoying, and i have changed numerous settings related to closing the lid and it makes no difference.

HDMI Audio disables itself when lid is closed

Hi,



Thank you for writing to Microsoft Community Forums.

• What is the make and model of your PC?
  

This issue could be possibly be due to the laptop speakers taking priority over the HDMI when the lid is closed. You may want to try the methods listed below and check if it works:



Method 1

Unplug and re-plug the HDMI cable:

• Close the lid and unplug the HDMI connection from laptop.
  
• Wait for a few seconds and plug the HDMI back in.
  

Method 2

Manage Default Audio Device:

• Right click the Speaker icon on the taskbar and choose
  Sounds.
  
• Under the Playback tab, set the
  HDMI Output as the Default device.
  

Note: If HDMI
is not visible, right click on a blank space under the Playback
tab and choose Show disabled devices.



Let us know how it goes.

Regards,
