Hi everyone, I'm currently using an external audio interface, model Steinberg MR816CXS. I recently installed windows 7 on a new pc, and noticed the surround5.1/stereo option was gone from the menu in the audio setting of my device. I èven tried to install the up to date drivers for my motherboard, but nothing seem to work. I notice the difference when I play videos on youtube for example, 25% of the audio content I play on there wont be played on my stereo setup. What are the options? Could there be a way I can turn it back to stereo? Thanks for reading.
