Desktop Audio

Can you please help.I recently purchased and HP 27b Curved 27" monitor.   While I can get sound from my headphones from the PC's headphone port, as well as from the headphone port on the HP 27b monitor, the internal/onboard speaker on the monitor do not work.   I guess the question is... does this monitor have on-board speakers built into the monitor.   It appears that their are speaker areas defined on the bottom of the monitor on the left and right, but all attempt to get sound from them has been unsuccessful.  I have tried multiple troubleshooting efforts, as well as installed multiple drivers in attempt to get the sound to come from the monitors internal speakers to no avail.    Again ... The sound is making it to the headphone/speaker jack on the rear of the monitor, so the HDMI cable and its associated audio is making it to the monitor, yet I get no sound from the speakers.   So again .. Does this monitor have speakers, if so what can be done to make them active.  I've loaded the monitors drivers in the my Window's 10 O/S, My PC is the newest OMEN 880 SE running an 8th generation Intel i7-8700K oricessir wutg ab NVIDIA@ GeForce@ GTX 1080 8G video card. The sound setting show the HP27b Curved  (High Definition Audio Device) as a viable output device as well as Digital Audio (S/PDIF) (2-High Definition Audio Device) The HP  27b is selected, and if I plug headphones into the headphone port it works ... it's as if the speakers are disable, not installed, or there is a failing component/driver.      I too am a retired HP employee and have extensive experience with PC's and the MS O/S.   This appears to be a hardware problem...
