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).

Just like in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875916 my sound stopped working with the new kernel "4.15.0-99-generic #100-Ubuntu SMP Wed Apr 22 20:32:56 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux". Rebooting into "4.15.0-96-generic #97-Ubuntu SMP Wed Apr 1 03:25:46 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux" sound works again. With 4.15.0-99-generic I do see a signal on the meters of the sound/volume control app, but physically there is no sound on either internal speakers nor on the headphones. With 4.15.0-96-generic everything is back to normal. My touchpad is working though (#1875916 seems to suggest that the touchpad stops working with 4.15.0-99-generic).
