Hi Robert, I recently upgraded to an AMD Ryzen system. For some reason the audio keeps jumping between channels. I am using the optical out on my old Recon3D card. Currently outputting to a receiver with Dolby Digital Live! enabled. I tried swapping cables/re-seating the card in different slots and the problem still persists. I doubt the card is failing because it worked fine on my old system/motherboard. Both Creative drivers and PAX drivers have the same problem running on Windows 10. Please help me! Thanks.
