I have just come back from holiday to find exactly the same issue....
I get normal sounding audio through the laptop speakers but some weird echoey reverb when listening to audio through headphones. Have tried listening to the same music through my phone and the headphones are fine, it is just when playing through the laptop.
I am a music producer so this is actually a huge deal, need it fixed or to find a workaround asap!!
Any help would be very much appreciated, thanks!
In the notifications area (on the right side of the taskbar), find the setting "Dell audio".
Right click this icon and select "Sound manager". There should be a setting under "MaxxAudio Pro" called "Speaker Enhancement". This will be set to "On".
Turn it off.
For my notes, click my username and send me the pc service tag number via private message as well as your Registered name
I am having this issue, but I dont see Dell Audio anywhere.... I have MaxxAudioPro installed, but I cant find a setting in there called "Sound Enhancement". Did I somehow install the wrong drivers? I got them from the product page.
Thank you for your message. Is this issue observed irrespective of the music application used, both online & offline?
Do you find the issue if the AC adapter is connected or disconnected?
Do you have any external device connected like a docking station, USB printer, external drives?
Please update the latest audio driver (Version: 6.3.9600.2202, A13) followed by the BIOS update (even if you have the latest version)
For my reference, please click on the message tab next to your avatar– click “New Message” & search for my Dell username (Sreejith R) & send a private message with the service tag, registered name & email address.
For me, the issue was resolved using either an old driver (from the Dell homepage, I believe it was version 126.96.36.199xx), or a newer version.
The newer version I'm currently using is 188.8.131.5244, but at that time it was not an official version from the Dell homepage. I got it as a link from Dell support, but the installation was not straightforward.
However, I believe in the meantime, Dell released an updated version as well - you might want to try those.
I had the same problem, caused I believe by the Realtek Audio Driver update Version 184.108.40.20642, A05
The fix for me: Download an older driver and install over the current one.
I downloaded this one: Version 220.127.116.1100, A00
(I also extracted and used the drivers own installer rather than the Dell one, I doubt that made any difference but just in case you get different results try that.)
I found turning off Maxx bass by itself was not enough.
Needed to also turn off the Nx head tracking (middle box) too.
Once both were turned off, echo has now GONE!
