Need help with non functioning "usb audio codec" driver. it's the driver my usb mixer needs and it just stopped working, no reason. trying to test the audio through the playback devices advanced settings results in an error "error failed to play test tone". a wierd detail is that different applications stopped working at differant times, chrome lost audio first, then discord, then skyrim, then reaper (audio production software).
thanks for reading, any help appreciated.
