I'm trying a while for solve this problem but I can't. When I install synapse 3 thx works perfectly, but when I switch off the computer or something else, thx doesn´t work, I can't hear anything. I tried to reinstall the drivers and restart the service but nothing... The only way to solve it is uninstall synapse and install it again, and only works the first time. Obviously i'm not going to do this every time. Any solution?
