At this point you call it a bad motherboard since that's where the audio is. RMA, start fresh.
I have a newly built desktop and just recently on 4/4/2020 all audio was gone I've done everything from installing new drivers restart my computer to run an audio test which can't do because it keeps saying the test tone failed. on top of that, I can't play Spotify not like I can't hear anything more like whenever I tried to play music it won't work the same this with other music players. I don't why this is happening I've never had this happen if anyone could tell me why I would appreciate it
