13 The idea of this generic sound card is a bit

18 So having this generic sound card allows all
19 benefit from the simplification of a new car
20 of the wide sample rates support through ASR
21
22 Note, The card is initially designed for tho
23 and PCM DAI formats. However, it'll be also
24 AC'97/I2S/PCM type sound cards, such as S/PD
25 long as the driver has been properly upgrade
