So, I've been having a issue with my optical out connection with my ASRock B450 itx. I have it hooked up to my Marantz Sr5009 receiver. And I go between my TV audio and Receiver Audio by switching it via task bar. But, Sometimes the audio comes out distorted horribly "screeching". Swapping from TV back to Optical does not fix the issue. Turning the receiver off and on does not fix it ether. Neither does turning the amplifiers on and off. Nether does closing the application and retrying. The only thing that fixes it is rebooting the PC. And it seems to always work just fine. So, I am almost positive the computer itself is sending the data corrupted. And Rebooting resets it. Any suggestions? It's really annoying and I don't want it to damage my speaker or amplifiers.
