Hmm. May be it is result of double stop. Please try this patch:

--- hdaa.c      (revision 230179)
+++ hdaa.c      (working copy)
_at__at_ -1351,6 +1351,8 _at__at_
         struct hdaa_widget *w;
         int i;

+       if ((ch->flags & HDAA_CHN_RUNNING) == 0)
+               return;
         ch->flags &= ~HDAA_CHN_RUNNING;
         HDAC_STREAM_STOP(device_get_parent(devinfo->dev), devinfo->dev,
             ch->dir == PCMDIR_PLAY ? 1 : 0, ch->sid);
