Low sound quality (possible ID-10-T)

When outputting to my video card I have very low quality sound vs the high quality that is coming in.
I tried to bring up the equalify window but it isn’t opening

Realtek onboard audio generic

VAC is installed but line 1 is perfect sound and direct is. But for studio line 2 isn’t.

I’m not 100% sure what you are trying to say here.

Lets take one thing at a time…
You say you cant open the EQ window, does the button show ?

Low sound quality, what do you mean by that?
The sound quality will be the same for all output devices unless you have manually changed settings for one of them using the standard windows settings.
Equalify does not down/up-sample the audio or change anything but the filters you put in.
