8 Front/Rear Multi-channel Playback
9 ---------------------------------
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-
18 (hw:0,1) is assigned to the second DAC for rear playback.
22 - The first DAC supports U8 and S16LE formats, while the second DAC
24 - The second DAC supports only two channel stereo.
26 Please note that the CM8x38 DAC doesn't support continuous playback
44 on and "double DAC" mode. Actually I could hear separate 4 channels
