Hello. So I am having an unpleasent experience with the audio on my new laptop when I first boot it up. Everything else works as expected just for the audio, it was very slow for the first time. The audio jack as well didn't work. I did plug it all the way if you were wondering. So I did a driver update since things didn't work as expected. So now I am in the situation where some part of the audio system in my laptop is not working properly. More details about the audio jack, when I reinstalled the latest driver from Acer, removing the latest one, the audio jack didn't work until I disabled the audio enchantment checkbox in sound setting. Not sure why but it fixed the issue for the audio jack.
For the first issue, in NitroSense app, in the Acer TrueHarmony settings, I cannot change the preset. The default is music, when I try to change to something else, it won't change and stuck at music. Hoping I could find a solution here. Yes I tried Googled for a solution but unfortunately I couldn't find one. I also tried reinstalling the audio driver multiple times. Ones for Acer and ones from Windows Update. I even tried to reinstall NitroSense just incase. For specific, I reinstall these drivers which are the latest from Acer website:
1) Audio Driver (6.0.9071.1)
2) Audio Console Driver (1.20.238.0)
3) XPERI DTS Utility (sound) (Didn't managed to install so I downloaded from Microsoft Store) (2020.4.45.0)
4) XPERI DTS Utility (DTS Console) (Shows need to connect external speakers/headphone to use DTS audio control) (
1.10.1.0)
5) NitroSense (
3.01.3020) 
My second issue is related to DTS:X Ultra , in that app, it kept telling me to connect external speakers/headphone to use DTS audio control. Apparently this issue is related to the new Windows update 21H1. Might as well include here just in case someone have a solution rather than rollback.

My third one just would be how to increase the sound loudness. If I can fix the above problem, it might fixed this third issue. Just at the moment, the max volume just isn't loud enough.
Finally here's some picture related to audio.



I am sorry if I spam, this is my first time asking for help. I am tired trying to figure a solution for this issue. If out of the box the issue was already present, I doubt this is an easy fix. I am sorry as well if my English is bad a bit as English isn't my first language. Thank you for your time. Have a nice day!
