Using ReClock 18.104.22.168. It seems like since I updated to Windows 10 build 2004, any time I restart my computer this setting inside ReClock Configuration gets reset. I need it set to my "NVIDIA High Definition Audio" device since that's where my AV receiver is. Is there a file somewhere where ReClock stores its settings that I can make read-only, or is there anything else I can do to make this setting stick through reboots? EDIT: I may have a solution. I've found that the ReClock settings are stored in the registry under the key HKEY_CURRENT_USER\SOFTWARE\ReClock\Config. So I can simply set up ReClock the way I want with the config utility, export the registry key, make a batch file with the line "REG IMPORT [exported reg file]", and finally place a shortcut to that batch file in my startup folder (which is a pain to access in Windows 10, but that's another story).
