Simplification of equations

Hello, I am trying to simplify an equation like E^(I y) x == 0 I would exspect Simplify[E^(I y) x == 0, Assumptions -> y > 0] to work, but it doesn't. It needs explicitly Simplify[E^(I y) x == 0, Assumptions -> E^(I y) != 0] which should be implied by the first version. Is there a better way? Best regards KUS
