This worked because we only ever had 1 CPU DAI for each rtd until now. But with multiple CPU DAI's, a new connection between a BE CPU DAI and the DAI widget should be established without affecting the previous connections. So, modify the loop to set the playback/capture widget for the first BE CPU DAI that does not have a connection established previously.
