Thanks

Every time I listen to music, the sound seems to systematically "dip" during playback. The problem is especially noticeable when listening to songs with a lot of dynamic range. 

I saw that this is an issue that was brought up earlier (in 2012) in this thread: https://h30434.www3.hp.com/t5/Notebook-Audio/Automatic-Audio-quot-Ducking-quot/td-p/1845265

The user describes the issue perfectly: "during the quiet parts of the song, the volume seems to automatically adjust itself in order to keep everything within an average range (quiet parts become WAY louder; loud bursts of sound are capped to a mid-level).  This seems to happen no matter what program I use to play music on, so I'm assuming it is a system setting".

I have a few troubleshooting steps we could try to fix the issue:  

Let's perform Windows Update and HP Support Assistant:

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates. Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.

Use the troubleshooting tool in Windows

The audio troubleshooting tool in Windows can automatically fix common audio recording and audio playback problems with your computer. Run the troubleshooting tool using the following steps:

• In Windows, type find and fix audio into Search, or right-click the speaker icon  in the taskbar and select Troubleshoot sound problems.
• Select Find and fix audio playback problems or Find and fix audio recording problems from the Search results.
• Click Next.
• Select the device you want to troubleshoot and click Next.
• Wait while the troubleshooter detects problems and makes changes (or prompts you to make changes).
• When the troubleshooter is done, the Troubleshooting has completed page is displayed, listing any problems found and what changes were made to the computer.
• Click Close.
• If a recommended action is displayed, select Apply this fix.

Restoring the audio driver in HP Recovery Manager:

1. In Windows, search for and open Recovery Manager.
2. Click Reinstall drivers and/or applications.
3. Select the audio driver in the list, and then click Install.
4. Wait for the driver to reinstall. When the installation is complete, click OK.
5. Close HP Recovery Manager and then restart your computer.
6. Test for sound. If the audio problem persists after reinstalling the driver, try updating the driver using Device Manager.

Updating the audio driver using Device Manager:

Make sure the audio device is enabled and then update the audio driver using Device Manager as follows:

1. In Windows, search for and open Device Manager.
2. Double-click Sound, video and game controllers.
3. If a sound device is listed with a down arrow, the device is disabled. Right-click the sound device name and select Enable to re-enable the device.
4. With the sound device enabled, right-click the sound device and select Update Driver Software.
5. Click Search automatically for updated driver software.
6. Windows checks for and installs any updated drivers found. The window displays whether the computer already has the latest available driver or if Windows was able to successfully update the audio driver.
7. If a window opens asking you to restart the computer, restart the computer.
8. Test for sound. If the audio problem persists after updating the driver, continue to the next step.

If you completed these steps and the latest driver was already installed, use the following steps to uninstall and then reinstall the driver:

1. In Windows, search for and open Device Manager.
2. Double-click Sound, video and game controllers.
3. Right-click the sound device and select Uninstall.
4. Restart the computer to reinstall the driver.
5. Test for sound. If the audio problem persists after reinstalling the driver, continue to the next step.

This is a common complaint with most HP notebooks manufactured within the last several years, including my HP 250 G4.

Assuming that your audio controller is manufactured by Realtek, the ducking (poor dynamic range compression processing) is driver related and can not be turned off or adjusted while listening through the computer's speakers. However, you can try the following in order to decrease this effect...

• Turn off all audio enhancements. (applet for your audio controller in the control panel)
• Keep the player's volume at 50% or below.

The dynamic range compression is not present while using anything other than the internal speakers, so audio sent to bluetooth devices, over HDMI connections or anything plugged into the headphones jack should not be affected.
