System volume slider does not work, except muting at lowest level

I have recently upgraded Gnome to 3.38 on a FreeBSD-12.1 system. I am using a DH67CL Intel mainboard with i3-2120 processor and using HDMI output for sound. 

The sound slider on the upper right corner does nothing if I increase or decrease. However, If I slide it down, the sound mutes. I checked that my device is a Intel Cougar Point HDMI output and it has a 'Vol' and 'PCM' as controls listed in mixertui. If I adjust 'PCM', I can increase or decrease sound volume. So, I believe Gnome's volume control is mapped to 'Vol'. So, in order to get sound volume control to work, mapping system sound in Gnome to 'PCM' is needed. 

I had also tried adding HDMI device details to /boot/device.hints and it did not work. Please help to make the sound volume control in Gnome-3.38 work. Let me know, if any other details needed.
