I would just like to first say hi as I am new here.
So I have an Onkyo HT-R591 set up using Audyssey 2EQ Full Calibration(with some custom db levels), when I play audio through my TV to my receiver(using TV/CD), the audio and bass are louder than when I play the same content through a standard HDMI input(eg VCR/DVR).
I tested this by playing a YouTube video off my smart TV and also playing the same YouTube video on my PS4(toggling between inputs). The YouTube off my TV(optical input TV/CD) is louder.
I tried to check if the audio settings were different in TV/CD, but they look the same as in any of the HDMI inputs. Maybe Audyssey doesn't work on input TV/CD?
Thanks for your help and I'll update if I find a solution.
PS: I love my receiver and 7.1 is great, I just noticed this(the above) and so did some of my family.
