Rocksmith not detecting sound

[tunnel2k7]

I've been playing without any issues up until now. When I start rocksmith I get an error stating "unable to detect sound, ensure you have sound connected". WTF...I'm on windows 10, and tried searching for fixes but nothing works. Anyone experience this?

I have gotten that error. I would get it once in a while and un plugging and plugging back in the hdmi wire would fix it. Also if i have my soundbar on thats bluetooth connected, it will give me that same error. I have to re select hdmi to play rocksmith.

Make sure your audio system is set to 48kHz/16bit or RS will throw that error.
