The only way to solve this is to replace your onboard sound chip with another sound chip and see if the new sound chip works. do some research and see what onboard sound chips work in programs like Sonar,. then see if it will fit in your laptop. If it does, purchase it and install it.
The other way to fix it is to get another laptop with a sound chip that is known to work well with programs like Sonar.
Allot of laptops do not have sound chips that will perform well with professional programs as because they have not have good drivers written for them.
Onboard sound chips are made for ordinary sound playback, not for DAW's
Do some research and see what laptops have the sound chips that will work.
