Tested sound cards
We typically run the sound system with 48000 Hz sampling rate and
periods of 2 ms (96 samples). The measured hardware delay (combined
input and output), as caused by block processing, USB BUS protocol and
anti-aliasing filters is given below. Please note that the values for
USB devices may vary slightly between jack starts and sound-card
