Realtek Audio driver causing audio and video delay

I managed to solve the problem without updating the drivers (didn't help).

1. Open device manager

2. Turn on showing hidden devices

3. Remove hidden (gray) unused audio and video devices. Pay attention to external monitors (TVs, MiraCast).

After that, everything immediately worked fine (even without a reboot).

I got an Inspiron 3501 and I've got this problem too.

At first I fixed it just uninstalling the Realtek Audio drivers and rebooting the pc, everything went fine.

Then after few days the problem came back and I don't know what to do now.

I'll try to get the specific driver the solution talk about and I'll give it a try, I feel really frustrated.

how you disable it im not logged into it

how do you turn off updates for drivers 

Editing the windows registry

I found that driver 6.0.9205.1 works just fine. It also brings back the Realtek HD Audio Manager in the control panel where you can set the equalizer.

Just found this online. This worked for me regardless of what version driver is installed.

Find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318}\xxxx\PowerSettings

where 'xxxx' is one of keys which contains

DriverDesc value 'Realtek High Definition Audio'.

Note: There may be multiple ones containing PowerSettings,

for example 'Nvidia High Definition Audio'.

You'll find there three binary values and set them:

ConservationIdleTime = ff ff ff ff;
IdlePowerState = 00 00 00 00;
PerformanceIdleTime = ff ff ff ff.

Also consider this thread, helped for me:

User HintD wrote this too, but I skipped the Miracast devices....but this was the important one.

If anyone else is struggling as much as I was, snaver's post in Reddit is what finally solved it for me without having to use the generic Microsoft driver:

In case this gets taken down someday, this is what Snaver wrote:

This frustrated me for ages after trying to fix for a separate headphones issues, somehow I seemed to have two versions of Waves MaxxAudio Pro Application installed - but not listed for removal/uninstall in Windows Control Panel.

oem11.inf wavespro9de.inf

6.2.0.719

1.42.18.0

oem106.inf wavesapro9de.inf

6.2.0.946

1.55.3.0

These appeared in C:\windows\system32\DriverStore\FileRepository.

Windows 10 Device Manager has got 'Devices by driver' view mode to quickly find and remove drivers, use this to find the duplicate waves drivers and click remove.

Hope this helps someone else as much as it helped me.

I had been following this discussion since I had the same issue. Instead of handling the registry, I had found a temporary fix which was to uninstall the audio driver and looked for previous versions on the Dell website and install them until a version worked just fine. But every windows update had to be dealt with by reinstalling the older driver that had worked for the audio to work fine.

But the good news is that recently, there has been an update that came with a complete fix to this problem and its been more than a month now that this issue was resolved on my device.

It sounds like you've done some troubleshooting and determined that the Realtek Audio driver is the problem. Here are a few things you can try to fix the issue:

• Update the Realtek Audio driver. Go to the Dell website and download the latest driver for your Inspiron 7506 2-in-1. Once you have the driver, install it on your laptop.
• Roll back the Realtek Audio driver. If updating the driver doesn't fix the issue, you can try rolling back the driver to a previous version. To do this, open Device Manager and expand the "Sound, video and game controllers" category. Right-click on the Realtek Audio driver and select "Properties". Click on the "Driver" tab and then click on the "Roll Back Driver" button.
• Disable the Realtek Audio driver. If rolling back the driver doesn't work, you can try disabling the Realtek Audio driver. To do this, open Device Manager and expand the "Sound, video and game controllers" category. Right-click on the Realtek Audio driver and select "Disable".

The audio and video delay you are experiencing could be caused by compatibility issues or outdated drivers with your Realtek Audio driver. It is possible that the driver is not optimized for your system, leading to latency in audio and video playback.
Additionally, conflicts between the Realtek Audio driver and other installed software or drivers on your computer can contribute to the delay. Outdated or corrupted Realtek Audio driver files may also result in synchronization issues, causing audio and video delay. Adjusting the audio settings within the Realtek Audio driver software might help alleviate the delay. To resolve the issue, consider upgrading to the latest version of the Realtek Audio driver or seeking support from Realtek's official website or customer support.
