Strange audio 'issue'

I have a JBL Tune 310C headphone as well as a Cyber Acoustics USB & Bluetooth Speaker Bar (CA-2890BT) in both I have a strange ‘issue’ -

If I select “Digital Output” mode the sound is considerably low, but if I select Analog Output and move the volute all the way up & then I switch back to Digital Output, the sound output is normal.

I wonder if it is an issue with both of my devices (which will be strange) or is it some sort of bug ?
I am on Fedora 41Ws with all the patches / updates applied.
I am using easyeffects, but this issue was there even when I was not using easyeffects.
