953 // Compute wake up time for device level to reach enough samples
955 // Device has 100 samples (48K rate).
956 // Stream has 123 samples (44.1K rate)
957 // cb_threshold = 512 samples.
958 // Stream needs 512 - 123 = 389 samples.
959 // Converted to device rate => 389 * 48000.0 / 44100 = 423.4 samples
960 // => 424 samples.
961 // Device needs another 424 - 100 = 324 samples.
962 // Time for 252 samples = 324 / 48000 = 0.00675 sec.
963 // So expected wake up time for samples is at level_tstamp + 0.00675 sec =
985 // to reach enough samples for one cb_threshold.
