Help with RealTek PC audio

Hello, I was using a optical cable from my PC to a Monarchy Audio DIP, output via XLR digital cable to a MSB Link DAC then out via a pair of RCA’s to a Modwright SWL 9.0 pre amp. I use a Antique Sound labs tubed headphone amp. I then would plug a Bose 2.1 audio system into the headphone amps 1/8 inch output. Works amazing, improves the standard PC sound by a lot, games or Spotify all sound way better, i can even listen to my HD600 headphones.


The BAD: I turned on my PC one day only to discover no sound! Plus now my DAC is showing 48KHz. So, i check all the Realtek settings and even though I put the Digital out on 16/44 (and the PC shows this) it still shows 48HKz on my DAC which will not work, it needs a standard 16/44KHz signal to work I think. bummed.
