Thanks, Liam. I'll split up the patch into 2.
Also, just a comment that it should not return an error when there is an ID mismatch. It just means that the command is not meant for this component and it should just pass it forward. I will change it to return an error if cdata is NULL.

This patch fixes the following:
a. source_period_bytes/sink_period_bytes calculation fix with the correct frame_bytes b. check if the ctrl cmd is for the volume before processing it
Could you do this as 2 patches. One minor comment below too.

return 0;We should return an error if cdata is NULL or there is an ID mismatch. These can also both be check once at the function entry rather than in the switch statement.
