Lack of equaliser controls on HP laptop

[PeterB78]

Following on from the previous comments about the  very poor design of the audio system with respect to the switching off of the equaliser/tone controls when headphones are plugged in.

Question is HP going to do anything about it?  Currently it makes the laptop totally useless in this mode especially when they have made an effort with the speaker system.

If they are not going to do anything about it is there a work around . Perhaps  some software to install another equaliser when in this mode

@PeterB78 Welcome to HP Community!

Please try the steps recommended below.

Go to Windows Device Manager > Sound, video and game controllers section.
In the list of audio device drivers, look for Realtek High definition Audio. This is the device driver for BeatsAudio (a little bit sneaky, wouldn’t you say?).
Right-click and select Disable. The downward arrow displays on this driver, indicating it is disabled. (NOTE: At this point, you won’t be able to play any music files.)
Right-click and select Update Driver Software.
Select Browse my computer for driver software.
Select Let me pick from a list of device drivers on my computer.
You should see a window that says Select the device driver you want to install for this hardware. NOTE: If you see a window that says something like This is the best driver for this device, exit the window and repeat steps 4, 5, and 6.
In the Model box, highlight Realtek Audio Device (this is the substitute audio device driver) and click Next.
At the Update Driver Warning window, click Yes. You should see a confirmation window with High Definition Audio Device displayed. Click Close.
In the list of audio device drivers in the Sound, video and game controllers section, you’ll notice that the High Definition Audio Device now displays instead of Realtek High definition Audio.
At the prompt to reboot, click Yes.

If the issue still persists try the steps recommended below.

Is the loudness equalization off? If not, please:
Right, click the speaker icon
select 'Playback Devices'. 
Highlight the default device
Click Properties
Click Enhancements tab
Next to 'Loudness Equalization' take out the check mark in the box.
Click Apply
Click OK

Lastly, uninstall the audio driver from the device manager and update the driver and BIOS using the HP support assistant.

You can update drivers on the PC using HP support assistant.
