I recently purchased the Nommo Chromas and they worked for a few minutes, but after I've installed Synapse 3.0 Beta and Razer Surround I don't have sound anymore. I uninstalled everything and just installed Synapse 2, which did not help, so I installed 3 again, but still no sound. Windows shows me, that sound is being send to the speakers and when I switch to headphones, I get sound. I also tried different USB ports and connecting via aux, but no dice. RGB etc obviously works and I find the Speakers in Synapse. Windows Device Manager also shows no issues. It's just as if they were muted somehow.
