So far, my system seems to be running stable but I am curious as to why and how the setting for my interface got changed and why it took S1 so long to give me a sample rate error. Maybe the root cause was a Windows update that somehow changed the setting.
Steve, I have had Window updates as well as Nvidia updates change my audio interface settings. Windows to Realtek and Nvidia to their audio. It can be a PITA. However just to be safe I would do a full anti-virus and a anti-malware scan.
