I am sorry if I explained this poorly, I am very unsure as to what is going on and I find it difficult to explain it. They both have AMD CPUs, which I am not sure if that helps. Furthermore, on my old PC it automatically updated one day and then the exact same problem occurred on that PC too which has different specs compared to my main PC. I have since updated back to the most recent version of windows because a lot of the programs I use didn't work as well and I am having the exact same problem I always had. I decided one day that I should try installing that version of windows on my main PC and it worked perfectly on that version from 2017. I decided to use my old PC that has a windows version from 2017 (I believe the windows version is 1709), and the capture card works perfectly using Amarec and the audio sounds great. I had always thought this was a problem with my motherboard, as the motherboard and CPU I am using is currently going through some USB intermittent connectivity issues (B450 Tomahawk MAX with Ryzen 5 3600), however I now have the most recent BIOS update which is said to fix those USB issues.
