 I don't know what is going on. Your sources probably screwed. Please
 recompile everything, just to be sure. It probably harmless, for now.

 Please enable vchans. Make sure hw.snd.maxautovchans=<greater than 0>
 and hw.snd.pcm0.vchans=<greater than 0> (on -current, this should be
 dev.pcm.0.vchans). Try again (remember that hint.pcm.0.dac="1").

 Expected.

 This version is much better than the previous one since you can
 configure total number of DAC. Since yours cannot operate more than 1
 DAC, dac=1 works flawlessly at the cost of enabling vchan (which is
 good).

 ... Recording in stereo is obviously too advanced
     and confusing for us idiot ***** users :P ........
