Let me correct myself there... significantly so.

I realized that I had made a config error in BIOS. I _did_ disable the onboard HDMI-audio. But I neglected to disable the onboard audio controller.

Having  done that, my system now reports no audio devices at all with aplay, but I DO see an audio device on 02:00.1, and since the 02:00.0 is the GT430, it would appear to be a device there?

j2 at MythBox:~$ aplay -Lv
pulse
    Playback/recording through the PulseAudio sound server
j2 at MythBox:~$ aplay -lv
**** Lista över PLAYBACK hårdvaruenheter ****
j2 at MythBox:~$

So, I guess that means that I have a bigger issue then I thought? But, I do see an audio devices listed as 0:
