Dell Xps 17 L702x right speaker hissing noise + sometimes it loses volume? what is the problem?

Jump to solution

Hello 

 I am facing an irritating problem, I noticed that my right speaker will sometimes decrease in volume then after a while it will return to normal volume/ or I believe it loses bass meaning the left speaker sounds louder and then the right speaker. Last night I noticed there was a sizzling sound from the right speaker, it wasn't loud but when the room is quiet then you could hear it. I don't know if the problem lies on the right speaker. 

Can someone please guide me to know what the problem is, my warranty just ran out last month so I have to figure on what the actually problem is first

I didn't notice this before but one of my headphone jack is loose,for example if I plug my headphones into the jack,you don't require any force at all to stick it in and out.

Maybe you should look into getting an extended warranty from Dell.

If you ever decide to work on it yourself you can get the part with the audio jacks from the parts-people (specialists in Dell parts). They also have the left/right speakers for $15. Their parts are mostly used but have a warranty.

Hello. If you listen through headphones but do not get the same symptoms then it is a hardware issue. Probably replacing the speakers will resolve it.

Hello Jimco

When I use the headphones, I don;t think It happens but I did notice was when I go to the audio software to change some settings randomly the speaker will return normal then low or I have to turn the volume up a bit for it to work.  Do you think its still the speaker issue, I've run the audio test by playing left and right speaker but they sound normal

Another way to test is to change the audio driver -- if you are now using the Realtek audio driver switch to the native Windows driver, or vice-versa. If the problem goes away when you switch drivers then it is a software issue.

To install the native driver, remove the Realtek driver. Open the Device Manager and expand the Sounds controllers section. Right click on the Realtek and select to uninstall. Put a check mark in the option to delete the files, and then ok. When you reboot, Windows will either install its own native driver or a Realtek driver if there were any other versions on the hard drive. So go back to the Device Manager and check for a Realtek driver. Keep uninstalling & rebooting until Realtek no longer appears under sound controllers. At that time you will see the native driver listed as "High Definition Audio Device".

Or if you are currently using the native driver, download the Realtek driver and install it.

Hello Jim

I noticed when I turned off the maxxaudio, both of my speakers (left+right) were the same volume playing but when I turned on the maxxaudio, it will play both loud but after a short while the right speaker will be lower than the left. I don't know if software can cause this since if it was then both speakers would act similar way.

I cannot find the realtek drivers as when I visit the page it only shows the manual, I am using Realtek ALC665 audio driver

To get the Realtek driver go to the XPS L702x downloads page, enter your operating system (Win 7 or 8) in the box, then expand the Audio category. To see if there is another version of the driver you can try, click on "Previous versions" after expanding Audio.

Note that if you want to try a version that is dated older than the one currently installed, first completely remove the current one by the method I described above.

Hello Jimco

 I think I would prefer to download the drivers from Realtek's website but I cannot locate the drivers plus I am not sure if it is compatible with dell xps 17. I have uninstalled the driver and booting up then re-installing but there are no changes.

When there is a major windows update(7) every month,I boot up the laptop to complete the updates and I notice the right speaker doesn't become quieter after using for the day.

The last fresh installation I have done was at april and after that with the all the drivers installed, I would use disk cleanup tool + disk defragmenter which does boost my bootup time faster but I am not sure if disk clean up +defragmenter could influence the drivers by corrupting/deleting,causing the software to not function properly.

I have uninstalled the driver and booting up then re-installing but there are no changes.

I suggest that you use the native driver for a day or two and see what happens. If the volume level of the right speaker still goes down while using the native driver but remains level in the headphones then I think it is a hardware problem, because the exact same problem is unlikely to be caused by 2 entirely different drivers.

To install the native driver, remove the Realtek driver. Open the Device Manager and expand the Sounds controllers section. Right click on the Realtek and select to uninstall. Put a check mark in the option to delete the files, and then ok. When you reboot, Windows will either install its own native driver or a Realtek driver if there were any other versions on the hard drive. So go back to the Device Manager and check for a Realtek driver. Keep uninstalling & rebooting until Realtek no longer appears under sound controllers. At that time you will see the native driver listed as "High Definition Audio Device".


When you have finished testing the native driver, install a Realtek driver. To get one direct from the Realtek site,

Go to the Realtek downloads selection page.

On the page click on "High Definition Audio Codecs".

Check "I accept" and then "next".

In the column named "Description" find the file named README. That has the instructions for installing or updating.

In the column named "Download", click on one of the server names to download the readme file.

Go back to the column named "Description" and select your operating system (and whether it is 32bits or 64bits) from the 1st 2 choices at the top of the list.

In the column named "Download", click on one of the server names to download the driver.

It will be compatible with your laptop. If you want one tailored for your model then get it from Dell. Dell gets Realtek to do some re-branding, for example naming the Realtek Audio Manager the Dell Audio Manager on some models. I'm sure there are other differences too but I have not done a comparison.

Using the Windows tools you mentioned will not harm the audio driver.

Hello Jim

I am still in the process of testing the driver but last night after I had removed the realtek driver, I needed to restart my laptop but I am worried if restarting  can damage the laptop such as laptop components by *clicking on start menu  then "restart" after a 2-3 hours use
