Ever since I got this thing over a year ago, I have been plagued by on and off issues with the audio interface, with issues ranging from it refusing to enter recording mode when I have a VST open, volume reduction having no mitigating effect against sound clipping. to and absolute deafening screeching noise whenever it is plugged in.
Sometimes these issues just seem to magically disappear, and I still have not been able to figure out any rhyme or reason to it. I just updated the firmware twice just to be safe, still nothing. Right now it's just flat out not giving me any signal.
I have a PC using the ASIO4All driver. Hope this helps.
