I cannot hear any difference in pop level am I using head of linux-omap or when merging sound-2.6/asoc on top of it. Of cource this pop noise can be codec output & load dependent and also possible on-board amplifier with proper power sequencing can mask the noise. For reference, output jack of the Beagle is connected directly into HSOL and HSOR pins. -- Jarkko
