Windows 7 Hardware Disconnect/Reconnect noise when monitor is in sleep - make it stop

Question

Whenever I plug either of two Windows 7 laptops into my Planar 27" monitor, I get a constant hardware disconnect/reconnect sound when the monitor goes to sleep. It drives me absolutely insane, so I shut off my speakers.

I do NOT want this. However, I want the disconnect/reconnect sounds for all my other devices, so the "just disable the sounds" 'fix' is unacceptable.

I have a suspicion that the cause is the speakers / audio playback device that's in the monitor over the HDMI cable, but I also don't want to downgrade my connection to an RGB cable. What better solutions are there?

Answer 1

1. With the monitor connected, type manage audio devices in the Start Menu search box

2. Right-click inside the Playback tab and make sure both the following options are checked:

   

3. Now if the offending device shows up, see if you can right-click and Disable it

Another place to check for the device would be in the Device Manager.

You can also check your sound card's (advanced) settings and see if there's any way to disable only HDMI audio and leave the video intact.
