I have a Dell G7 7790 laptop. My Realtek(R) Audio driver updated 2 or so months ago, and ever since it did that my sound has been <Profanity removed> up.
The actual sound coming from the laptop speakers is totally fine. However, if I put in a headset or earphones, the quality is atrociously bad. It sounds like I'm listening to it through the wall of a different room.
I've tried to uninstall/reinstall the drivers but it's not fixed the problem. At this stage, I have no idea what the problem is.
The sound settings might need to be adjusted. Right click on the volume icon (the right side of taskbar) to get to settings. Run the troubleshooter if needed.
Hold down WinKey and R to open the run dialog box.
type mmsys.cpl sounds to open the Sound properties.
Under the playback tab, double-click on the affected device.
In the new window that appears, click on the advanced tab.
Under the signal enhancements section, uncheck enable audio enhancements.
Click OK on both windows to apply the changes.
Note: If you have the MaxxAudioPro app, turning off the enhancements there will still result in altered audio. The above steps should disable those enhancements as well, resulting in unprocessed audio regardless if the MaxAudioPro setting is on or off.
Check for your audio card driver. An outdated or corrupted audio card driver could result in your problem. Make sure the one in your computer is the best-matched one.
If you are not sure if the problem is from the device driver, then it is suggested you download a device driver scanning and updating software. Personally recommend Driver Talent to you. One of its highlights is easy to use. It could scan all drivers in your computer, list the problematic drivers, then fix it by just one click.
Well, you could also update the audio card driver in Device Manager.
Finally, go to manufacturer's website and download the proper audio card driver is also useful method, however, it is not suggested because it might be time-comsuming.
Good luck man.
