Is this the right fix here? I am not super familiar with the driver but it appears to contain an "AIFOUTL Mux" control which is not connected to anything. Looks like maybe this is a mistake the mux is indeded to be included in the path? Feels like we should either remove the control as well or hook it into the path.
Thanks, Charles
