You need to either have an asound.conf to override the default order of soundcards or you need to pass the snd-index option to alsa so hda shows up as card 0. Most apps default to card 0 especially the ones that don't use alsa and use stuff like oss etc. I put something like this in my modules files years ago: options snd-da-intel snd-index=0 do check this in the alsa docs because I can't remember dashes or underscores. regards, Kerry.
