Do you have the EQ and Bass Boost turned on?
Can you post me a screenshot of the audio page for your ROG Theta 7.1?

Can someone help me.. Volume is very low with 7.1. What should be sound preset in games (in game settings) for the 7.1 sound (home cinema, headset, 3d headset..)? Where i can find good EQ settings for gaming. When i set up 7.1 headset through Windows 11 should i choose "select full-range speakers"? There is option to choose: Front left and right and Surround speakers.
Have a play around with Armoury Crate, the options are quite complete and you can create your own profiles.
Only set the front channels as full range, so that the low frequencies from the surround channels can be redirected to larger drivers.
Note that the effects from surround channels are typically subtle to give you a sense of presence or surprise when there should be, they are not supposed to be overwhelming or noticeable at all times.
