I use Lenovo laptop I9 to run cubase pro 13 with no external sound card because I just want to do editing and mastering on it. No sound recording is needed. Please show me how to set up the audio setting because either no sound come from the laptop speakers while there are signal bars jumping up and down, or, the speakers work even I already plugin the earbugs. It seems the laptop cannot control to output to the headphones and also cannot control the audio level. Can anyone show me the solutions? Thanks.
