193  *  Add a delay of 1-2ms at each control message handling
195  *  Add a delay of 5-6ms at each control message handling
197  *  Add a delay of 50ms at each interface setup
199  *  Perform sample rate validations at probe

215  *  Force an interface reset whenever stopping & restarting a stream
218  *  Do not set PCM rate (frequency) when only one rate is available
