Same issue here on a Dell Inspiron 13-7378 (ALC3253). Audio was working fine on the previous kernel (4.15.0-96-lowlatency) and after update to 4.15.0-99-lowlatency there is no sound from the internal speaker and also the mic is not working. The sound works fine on an external USB device (plantronics P610).
