U4320Q, external speakers volume control issue
I just got a Dell U4320Q and started having compatibility issues with it right off the bat (after having an LG 43UN700 working seamlessly in my workflow). This time the issue is that I cannot control the volume of my external speakers plugged in into the monitor. I called Dell support but they couldn't figure out how the monitor is supposed to work and the support folks were very unprofessional and ignorant
Specifically regarding my issue, there are actually 2 things that do not seem right:
1) Both the monitor's internal speakers and my external speakers are playing at the same time when I plug in my external speakers. When I change the volume, only the volume on the internal speakers is changed. This never happened on my LG monitor, the expected behaviour is the sound playing from the external speakers when they're plugged in and from the internal speakers otherwise.
2) I go to the monitor menu and disable the internal speakers (with my external speakers plugged in). Now only the external speakers are playing. Next, I try changing the volume and I'm seeing the volume bar changing the volume level but the actual volume of the speakers doesn't change. The expected behaviour is that changing the volume should indeed change the volume of the external speakers.
I'm a software developer and I usually prefer Dell products over other stuff... Hoping someone can help me to resolve this issue. Is this a defect of my monitor? Is this a bug that can be resolved with a firmware update? Or should I just return it and have peace with my LG monitor?

Update September 28, 2021 = Response for the Dell Displays Team.
The U4320Q is working as designed. The line out is considered a fixed audio output and cannot be controlled by adjusting the U4320Q volume adjust. It is best to have the U4320Q and Soundbar (line out) adjusted for proper audio levels. Then use the Microsoft audio adjust slider as the master volume control. This is the same behavior used in TVs with external audio receivers. The line outs are always fixed output.

I am interested in this topic. Please do let me know if technical support can come up with a solution
Since Computer is pushing audio through HDMI cable to Monitor to Speakers
So instructions from the computer are being sent to the monitor
Awe need to know how monitor is utilizing that information.
The fact that both monitor and external speaker play at the same time, is a poor Design, monitor speaker should go off as soon as Speakers are plugged in to it.
From Monitor's OSD menu > I see an option or increasing and decreasing Volume
Could you please check and confirm if that works.
If that works to control the volume of external speaker.
Dell will have to make changes in monitor's firmware, so treats external speakers as it's own whenever they are plugged in.
If that also doesn't work
IN Audio panel of your computer are these speakers getting detected as default playback device or your display is still the default playback device.
