Switch mode to linear

Hi, Am wondering if it’s possible to replace a switch mode psu with a linear? Have tried powering up a Bose speaker from a 12v source via a dc to dc converter to19v as the required I/put for the Bose...speaker powers up ok but I get no sound from it Am assuming that the 2 types of psu’s Are not compatible in this case

Any assistants would be much appreciated Paul.
