Loading driver aftre boot seems have different device probe order. That causes HDMI HDA codec on video card to be probed either first or second. It is not snd_hda problem and could be handled just by choosing right pcm device to use (possibly via hw.snd.default_unit sysctl). Lack of audio redirection can probably be explained by CODEC configuration made by BIOS. I suppose that front connectors are configured as separate pcm device. -- Alexander Motin
