Windows 10: No Sound from DP on monitor.

I have an ASUS ROG Swift XG27AQ Gaming Monitor and when I have it connected via HDMI port there is sounds from the built in speakers but when I switch to the DP I no longer get any sound from the monitor. I have the latest BIOS and drivers for my motherboard. TX Gaming B760M WiFi I know the speakers work because audio output from HDMI works fine. speakers set to 50% and mute box is unchecked. Running Windows 11 Proi713700KFRadeon RX 7800 XT 16GB

dual monitors stops sound

Hi David,

Thank you for posting in Microsoft Community.

To assist you better, I suggest you to answer the below questions.

• When will the sound disable, when playing through main monitor or the extended monitor?
• Did you try enabling the sound from the sound drivers and check if it helps?
• Since from when are you facing this issue?

This issue causes because the monitor automatically takes the HDMI sound as the Default input. Disable and enable the speakers and check if it helps.

I suggest you to try the below steps and check if it helps.

• Right click on the volume control and then
  Properties,
• When you connect the HDMI it becomes the default output device, even though it has no speakers.
• You need to change this back to "Speakers" and set as default.

Hope this helps. Keep us posted to help you better.

 

Windows from HDMI monitor move to DP monitor when monitors go to sleep.

Hi Bobbeloos,



Welcome to post in Microsoft Community.

I'm Mosken, I do apologize for the inconvenience that you're experiencing right now, let me help you figure it out.



According to your description, I knew that you have two external monitors of similar model connected via HDMI and DP, but when the system goes to sleep, the DP-connected monitor goes straight to black, but the HDMI-connected monitor shows "no signal" and then goes black, and when you go to sleep from sleep, the DP-connected monitor goes straight to black All windows in HDMI monitor moved to DP monitor when computer was woken up and the resolution was not normal. If my understanding is wrong, please correct me in the reply.



Based on the available information, the speculation is that when the system goes to sleep, your HDMI connected monitor will be directly disconnected, it is recommended that you turn off "Allow the computer to turn off this device to save power" by follow steps. "Win" + "X" > "Device Manager" > "Display Adapter", double click "Display Adapter" to expand the entry, you will see a list of your monitor device names, then select your external monitor device names(try both), right click > " Properties" > "Power Management" tab, then uncheck "Allow the computer to turn off this device to save power", then press Enter to confirm.



The above steps are provided based on the information I have learned so far, I wish that will be helpful to you. If your problem still cannot be solved by these steps, you could tell me the specific situation in the next reply. I will continue to assist you in solving the problem.

Answering your 1st set of questions above:

1. I use Method 1, which you detailed.
2. Yes.
3. Well over 2000.
4. Everything works just fine when 3 monitors are connected via HDMI, DVI-D, and DP. Once 2 monitors are connected via DP, the above problem presents itself.
