I'm not familiar with what the module creation IPC update does, but this is stored at widget creation time and can be used later when we create the messages.

…t of a module Based on the input and output formats we can evaluate what param might be changed by the module instance. If there is a difference between the input rate/channels/format and the output rate/channels/format it means that the module can change one or multiple of the params. Store this information during init for later use. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>
The process module can change different parameters in the audio path and this change has to be properly evaluated and applied. In case of playback we are converting from multiple input formats to a single format (or just passing through without change), the output format lookup must be based on the input format. In case of capture, we are converting from a single input format to a format which is to be passed to the FE, we need to use the input parameters and the FE parameters to be able to find the correct format: for those parameters that are modified by the module instance we need to use the FE parameter while for the rest we use the input parameters.

The process module can change different parameters in the audio path and
this change has to be properly evaluated and applied.
In case of playback we are converting from multiple input formats to a
single format (or just passing through without change), the output format
lookup must be based on the input format.
In case of capture, we are converting from a single input format to a
format which is to be passed to the FE, we need to use the input parameters
and the FE parameters to be able to find the correct format:
for those parameters that are modified by the module instance we need to
use the FE parameter while for the rest we use the input parameters.
