Almost inaudible sound on HP Compaq 8100 Eleite SFF

[mdcalvert]

I have three identical HP Compaq 8100 Elite SFF Desktop PC's. 

On two of the three, the system speaker works perfectly. 

On the third unit, the audio output of the system speaker is bartely audible - with all audio controls set for maximum volume. 

All audio and device drivers are the same.

OS is Windows 7 Professional SP1.

These PC's were refurbed by Joy Products and I purchased them in January 2017.

I have removed the device and allowewd it to be found and reinstalled -- no change.

I have updated the device drive - no change.

I am curious as to why the SYSTEM SPEAKER is not listed in 'audio devices' .

Any help will be appreciated.

Uninstall the existing driver from device manager and install the latest drivers from HP webpage.

Restart Windows Audio Services 

1. Run -> Services.msc

2. Select Windows Audio service -> Restart the service. 

If the issue remains same post OS reinstallation, a hardware replacment is advised.

Thanks RaveenB,

I have uninstalled the existing driver and restarted the machine and then - after the speaker was 'found' and reinstalled - deleted the driver (it was the same as before) and downloaded and installed the driver from the HP driver list with no improvement.

I have so much new software loaded onto the machine that I am reluctant to swap it for a new machine under warranty.

I will try to do something else.

Thanks anyway.
