XPS 9520, audio quality decreases

@DELL-Nathalia M @Dell-BradL , all of the information you are requesting is already included in this thread. 2.4ghz wireless headphones will disconnect from zoom or discord (probably others as well) when audio from another application begins playing. If Bluetooth headphones are used the audio quality immediately changes to extremely low quality. There is a way to fix this but it is extremely complicated and causes other issues. It requires changing to unsupported audio drivers and disabling all of the waves processes and services. A clean install of windows was also performed. This causes other problems though and is not a reasonable solution for the average user. I hope that Dell and its affiliate software companies can develop working drivers and software that makes these XPS devices usable for everyday video calling while gaming. Gaming while on discord is a great way to aggravate the issue. Playing YouTube while on a zoom call is another way to aggravate the symptoms. Please let us know when a solution has been found. Thank you for removing the solved tag from this issue since it is not solved. Much appreciated.

I have also encountered a similar situation where, after the support team replaced the mainboard, reinstalled Windows 11, and updated all drivers and Windows, the issue persisted.

This problem occurs consistently when using a Type C dock, external speakers, or microphone, where they randomly disconnect and require reinserting the dock. I hope Dell pays more attention to the user experience and addresses this issue.

I have also been having this issue since I got the laptop (about a year).
I've been through several sets of headphones and hunting through the settings of every video/audio driver and app I have installed (NVidia, Realtek, Waves, Discord, Windows Audio).
I've been on Windows 11 since the beginning and have updated all of my drivers at multiple points in the last year.
I use USB audio, generally through a dock connected to the Thunderbolt port.

Glad to know it's not just me facing this issue.

I eagerly await updates which may finally fix this.

Our team would like to look into this further. If anyone is having trouble with audio on their XPS 9520, please use Get Help Now. If you have trouble using chat/contacting our team please let me know. The details shared will allow us to investigate this further. 

Here is another possible workaround to try at this link

Symptoms

Dell optimizer is not installed on my laptop and can not be installed because according to the installation file and Dell website, it does not support XPS 15 9520.

If XPS, try : MyDell > Audio > Voice > disable "Remove Noise" under Microphone and Speakers. 

Reboot, and try if that helps. 

Audio disruption with Intel 12th and 13th Generation Processors with Dell Optimizer or Waves MaxxAudio Pro

Additional testing #1 =
* Control Panel --> Sound--> Enhancements
* Disable the enhancements, then restart the system and test

Additional testing #2 =
* Disable Intel smart sound technology, then restart the system and test

MyDell on my laptop does not have an Audio section.

1) Audio Enhancements is already off.

2) The internal speaker on my laptop couldn't be recognized after disabling Intel smart sound technology in Device Manager.

We are in August and I have to reconnect my USB headphone 100 times because my laptop can't recognize it, Besides the poor quality of the sound and microphone noise, this is unbearable! When your update that was supposed to be released in July will be released then??

I have similar issues, experiencing it especially in Microsoft Teams but I did test other conferencing solutions, same issue. Headset randomly stops working. With my Jabra Evolve 75 it will disconnect me from the call, with Bose I stay in the call but people can't here me and I can't here them. When entering calls, sometimes I only hear distorted roboter sounds - unplugging the dongle or cable and replugging helps with that usually. Laptop is basically unusable since half a year - never ever will I buy a Dell again.

Hi all, have the exact same problem on my XPS 9720 when receive slack's notification, no chance to fix at all.... 

For who have audio quality decrease symptom, can you try below and see it that helps ? 

1."Win" Key + R, enter "services.msc".

2. Scroll down and find "Waves Audio Services", double click to enter the properties page.

3. Press "Stop" and then press "OK". 

4. Re-start the system and see if symptom presist ?

There is a rough fix posted on Reddit. The guide is tricky to follow and results in your headphone jack no longer working. Create a restore point before performing the following steps in case it messes your audio up, as it took me a few tries and tinkering with drivers. The steps involved include going into task manager and ending all processes that have the word or association with the word "waves." I believe there are at least 2. Then in task manager, go into services and disable any "waves" services. Again I think there are 2ish. Then right click on any service and select "open services,," where you will again search for anything "waves" and disable it. I would also check "start up" in task manager and disable any waves stuff in there as well. Once this is done go to device manager and find the drop down "sound, video and game controllers." From the list, right click on "realtek (R) audio" and select update driver then browse my computer for drivers. The next page will have a check box that says something about only searching for compatible drivers, you want to check that box so that it looks for all possible drivers. Once you do this you scroll the list till you get to Microsoft, select it and then choose the most recent HD option. Once you do this, restart the computer. Check your audio. If it sounds like garbage go to the Dell website under support and go to download driver (or something like that) then look for audio drivers for the 9520. Select the realtek driver without waves. Once you install this driver your computer should restart and then check audio again and it should be better. After trying this please report back to confirm if it worked. After doing this my headset is no longer disconnecting inputs and outputs while on voice/video calls. I based this off a thread i found on reddit https://www.reddit.com/r/DellXPS/comments/12ytc86/comment/jmcvmyf/?context=3

Again this is not a perfect fix as it seemed to disable my audio jack and is pretty insane for an average consumer to have to navigate these steps just to have functionality of their computer. Dell should be able to take this information and provide an update that fixes the issue. Dell, please confirm on this thread when an update has been created that fixes the issue. Thank you.
