'Ello again! Hope all are well! Another lockdown day, another poser. Have a second (main gaming) box running through an Aten switch (CS-1744) along with the laptop I'm using for workystuff. Sound from laptop speakers was a shocker so had a Cambridge USB DAC plugged in and running through the switch - sorted. Whenever I/the kids wanted to game on the main box, I just popped out the USB DAC from the laptop to the main box physically and everything was fine (with correct drivers installed, of course) bar reduced volume on main box vs the laptop, oddly... I then thought I'd buy a cheap Sabrent USB DAC (since everyone and their mouse seems to be buying Sabrent SSDs these days) to chuck in the back of the gaming box purely to save swapsying, but even though it's a PnP job (AU-MMSA), something has gone the way of the drain. I can still get sound from the Sabrent to the switch/amp, but the channels are swapped, so when I do a Windows sound test "L" is now a weak R speaker output and "R" is now a stronger L speaker output. I switched the Cambridge back in to the gaming box to test and same occurred. I plugged headphones into front panel and same occurred. By the way, I'm using USB because I think the board's back panel jacks are screwed (or something else, but either way, the green jack does nothing now when used directly). I've plugged straight into the headphone output of the amp to eliminate speakers and same occurred, so it seems it's definitely a PC issue. I've now uninstalled the Cambridge drivers but no difference. Board is Asus (grr...!) Maximus IV Extreme-Z. Was working fine until switch of USB sound adapters. Is there something I'm missing/something else I can try? Thanks in advance, team!
