System sound recording not working

I have followed this video however the system or stereo mix doesn’t work only works on microphone and the sound isn’t clear. i have logi tech speakers and logi video cam plugged in, is this the reason it doesn’t work or something else? thanks!

You could try changing the host from MME to WASAPI, then recording from “your output device (loopback)”.
