Not that is effects your issue much, but I wonder if your XPS-15_9520 also has the Nvidia-card or just the on-board Intel video.

I suggest you try a USB-based headset. This will have it's own "sound card" and drivers (the on-board audio-device and Waves-Maxx DSP nonsense will not even be used).

If you need some purchasing suggestions, just let me know. Mention if you want gaming headset (like Logitech) of more business-like like Plantronics. Post my name in thread so I will be notified.

I don't have much experience with chat type applications, but maybe a couple of things to visit.  I, cannot verify what you are attempting, is even workable.  I am not on a Dell system right now but I will check and get back if I notice anything with such an operation.

You are saying just one process at a time, Zoom or YouTube, works fine?  It is only when you run a second, similar process that problems occur?

Have you tried lowering the audio quality?

Does it make any difference whether the system is plugged in or not?

My first thought would be to check the settings in the attachment.  You can get there by using mmsys.cpl in a run box.  Perhaps, if apps were allowed to share the devices, they would not disconnect when another one was used.

Have you verified, since all of this is online, that your internet connection is adequate?  If your system was seeing deficiencies during these sessions, it might try to make corrections to the current configuration.

I think you have proven the problem is not based on your computer.  

discord and zoom are two of the most popular voice chat applications and discord specifically is designed to be used while streaming or gaming with friends (tandem applications with sound running at the same time). My XPS 7590 never had any issues doing any of this and I had 3 of them, which all were able to do this simple task. I am currently using a 6 year old microsoft surface pro 4 in place of my brand new xps 9520, which is able to do this task. This is a normal function of a computer and for "the best windows laptop" to not be able to do voice calls while doing other computer tasks is wildly frustrating. It is reproducible when running a voice chat app like zoom or discord while also having audio playing through another app like youtube or a video game (simple bread and butter stuff like communicating with a friend during a game like "Among Us").

Changing the audio quality doesnt seem to alter the issue.

The problem happens when plugged in or on battery power indiscriminately.

I have gone through the process of contacting the applications support team and done hours of tinkering in the applications setting and windows settings and no change has come from it. I have reinstalled windows 9 times. 

I have the fastest internet you can buy in a major city with fiber optic run straight to my house and the problem persists when on a wired connection through my dell docking station and when on wifi. It does not happen on other devices like the before mentioned surface or older xps 7590.

I dont understand how this product is selling like this. I have had 3 and they all have the same problem. its causing me to miss lectures, not be able to join in on discussions for group assignments and I cant play games with my friends. I should have got a Macbook.

My units have all had the rtx 3050 GPU. I have a wireless steelseries arctis 7 with a USB receiver, which i have tried with and without its own software. The problem is reproducible with every audio device i have looked up. I will try again with devices through the audio jack and fully usb wired connections, but this has already been tested and failed. Thank you for your suggestion.

This is how I reproduce the issue: 

- Open youtube shorts (shorts allows you to easily switch to a new video by pressing the down arrow, which initiates the problem).

- Open a zoom meeting

- At this time both youtube and zoom are using the same input and output. Be attentive to the sound quality of the youtube video. It will have likely changed. If it hasn't then go to the next video and then go back to the previous video (becasue you know what the previous video is supposed to sound like). At this point Zoom usually shows a pop up saying it cannot detect my microphone or speakers. This is easily resolved by just clicking test my device, which seems to turn the device back to zoom, (very annoying and not working properly). Now with the youtube shorts video still playing, end your zoom call and listen to the quality all of a sudden come back to your headphones. This is reproducible every time with multiple different headphones. it seems like the routing of the signal is not able to handle two applications or something which is just unheard of, let alone on a $2500 computer. like I said my $1000 computer from over 6 years ago handles this just fine and so did the XPS 7590 before this.

I also tried disabling exclusive mode and it changed nothing (I was really banking on it working).

Actually, I have the XPS-15_9520. Runs fine for me.

Be sure you are running the latest BIOS/Firmware (and all the sub-components also got updated ... like Thunderbolt ports).

You said you reloaded Windows-11. Was that Dell's version or Microsoft's? If Dell's, try uninstalling Support-Assist and some of the other heavy Dell driver-suites and Apps. Or, just install Microsoft's and use only drivers from Windows-Update (no Dell Drivers or Apps).

Be sure AC-Adapter is plugged-in and running in High Performance mode. Be sure all settings in Power Profile are maxed-out and all the limiting-stuff is disabled.

Discord should be fine, but there are some settings within.

Zoom is known not to play nice with other apps and barely functions on some hardware. If you are using it from a browser, try the native Windows App.

Your problem might be your Browser, or it's settings. If using Edge, try Chrome.

Be sure Nvidia card is configured to always run Apps (especially the games) in High-Performance mode.

Your problem might be your USB-Adapter/Hub. Try connecting charger and simple wired-USB Headset to laptop directly. Use one of these if you must.

If you are using Bluetooth (2.4ghz), be sure your WiFi Access-Point is instead the 5Ghz one.

Yes, put the fancy wireless SteelSeries Arctis 7 aside and test with something like this. I'm wondering if it's wireless radio is conflicting with your WiFi or maybe it's drivers are not quite-right (to allow concurrent apps operation).

If you want a MacBook, then I suggest you get one. Get a really nice/loaded one. The Mac-Studio (with M1-Max) is also nice if it doesn't need to be a laptop (sounds like you have plenty of those). However, remember that you can't get them with Nvidia card (for gaming) and you can no longer BootCamp them (so you will be limited to games and Apps that run natively on macOS).

I am glad yours works as this means there is hope for me. However, I have had 3 9520's all with the same problem and none of my other computers have this problem including my 2019 xps 15 7590. 

- Bios is up to date and this has been verified by Dells support assist team multiple times, along with attempting to update drivers for ever component imaginable.

- I have reinstalled windows 9 times total across 3 9520's. One of those times was a microsoft version on a new drive to eliminate the partition. I find it hard to only use windows drivers as the support assist app is handy for keeping my computer up to date, but if it is the only solution I will do it until I can afford a macbook... Given that I didnt have any luck with the microsoft version of the windows install, I am not overly confident that it will solve the issue, but worth another try at this point.

- AC is usually plugged in when issue occurs but not always (regardless, a laptop that cannot be used without being plugged in defeats the purpose of a laptops, doesnt it). I am confident this is not contributing to the issue though becasue it happens when plugged in. I have tried with power manager set to the highest mode. no change.

- I have had lengthy conversations with Discord support and tried all of their suggestions to no avail.

- I tried Zoom to help rule out discord as being the only app that causes the problem as the issue was originally noticed when trying to game when on discord. Zoom is just easiest to view and explain a reproduction of the issue.

- I am using Chrome and all apps are the desktop version. the browser doesnt seem to be the issue since this same problem happens when gaming which doesnt use the browser.

- I have the RTX 3050 set to run all relevant processes

- I have used 3 different usb hubs and all 3 USB-C ports on the laptop and reproduced the issue indiscriminately. One hub is the Dell docking station, another is the one provided with the laptop and the third is a 3rd party USB hub from HOOTOO. Issue present regardless of which devices im using.

- I am not using the 5G wifi and this happens when I use a wired connection as well.

- I have reproduced the problem without using a head set and only using the laptops built in speakers and microphone. I have also used other bluetooth ear buds, wired speakers and usb microphones. All still result in the problem.

- Id love to get a macbook at this point but since I have spent $2000+ on this laptop without the ability to return in and use that money to get a macbook I am stuck with this product. I am also in my 8th year of university finishing my masters so I am extremely broke. I feel like I am. TOS76>

. I can barely believe that yours works given the fact that I have had 3 systems that have the same problem. This is wild. Thank you for your suggestions, it is appreciated.

Are you getting any indications in the Events tab of the different devices as to if and why they might be losing the connection?

Knowing if it only happened if plugged in or not is just a troubleshooting step.

Have you been able to tell if either the audio out or the Microphone in, is causing the problem?  

The 9520 is probably a modern standby system.  Is the 7590 also one of those?  Again, just another troubleshooting step.

Since Bluetooth headsets seem to go around Waves, it is probably not responsible.

The audio on recent systems changed from a Realtek Audio to a Realtek USB Audio version, which puts the audio through the PCIe bus.  This change may be involved.

You might try not letting one of those apps have access to the Microphone, just to see if it makes a difference.

You stated you have used both Wi-Fi and Ethernet, but you did not mention what the Network Link Rate was with those options.

Hopefully, you and @Tesla1856 are talking apples to apples as far as the exact process you are using.
