Thank you, owner. It's really good to use your own.Previously, the effect of using the Chinese SRS Audio Sandbox passed on by others was good, but the volume should be adjusted more than 80%. The most important thing is that the computer and headphones have sound at the same time after the headphones are plugged in.Later, it was uninstalled. After it was installed according to the building owner's method, neither the system voice nor the player voice could exceed 50% (for fear of disturbing neighbors). Turning on Realtek has a variety of sound effects and environments, beating SRS Audio Sandbox!Thank you again!
