Hi@moprice64, Welcome to the HP Support Community!

I understand you have audio issues with your PC.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

As you mentioned when you play audio on your PC the audio is muffled after the windows update.

Please provide the product number of your PC to assist you better.

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 or IDT 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 High Definition 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 the 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 or IDT High-Definition Audio.
At the prompt to reboot, click Yes.

If the issue still persists try the steps recommended below.

background intelligent transfer service (BITS) transfers files (downloads or uploads) between a client and server and provides progress information related to the transfers. If the BITS service is turned off, windows update may have problems delivering files to your computer.

Also, try the steps recommended below.

1. In the Sound settings, click on Properties while selecting your Speakers

2. In the Enhancements tab, click Disable all sound effects

3. In the Advanced tab, unclick "Allow applications to take exclusive control..."

4. Apply the settings and test the sound.

Start the BITS service click start, and then click Run.

Type services.msc in the open box and then click ok.

Right-click background intelligent transfer service, and then click properties.

On the General tab in the startup type box, click Automatic, and then click apply.

In the service status section of the Properties dialog box, verify that the BITS service is started. if it is not started, click start.

Click apply, and then click ok.

Also, uninstall the audio drivers from device manager and install the latest audio driver on your PC using HP support assistant.

If the issue still persists uninstall the audio driver from the device manager and install the drivers using HP recovery manager.

If the issue still persists try running a system diagnostics test from your PC and check if the hardware components on your PC are functioning correctly.
