While trying to update to version 3.1.x, I foolishly typed ssu release 3.1.0.12 instead of ssu release 3.1.0.11. Only later I noticed my mistake. My attempt at downgrading to 3.1.0.11 (I know this is not recommended) left me with no audio.

Is there an easy way to restore audio (i.e. re-installing some rpm)?
