The line out from the motherboard rear sounds blown out after switching out my power supply, from Superflower Leadex III 850w to NZXT 1200w. I can hear the audio peaking a lot and sub woofer is louder after the swap. PC Case front doesn't have the same audio blown out issues. I use rear channel output as a temporary solution as I use a subwoofer (sub out) for my setup.
Reinstalled the drivers multiple times and used driver store to ensure it is fully cleared.
PC is stressed tested and other issue, only audio from line out.
