8 Front/Rear Multi-channel Playback
9 ---------------------------------
11 CM8x38 chip can use ADC as the second DAC so that two different stereo
12 channels can be used for front/rear playbacks. Since there are two
13 DACs, both streams are handled independently unlike the 4/6ch multi-
14 channel playbacks in the section below.
20 There are slight differences between the two DACs:
22 - The first DAC supports U8 and S16LE formats, while the second DAC
24 - The second DAC supports only two channel stereo.
