I thought it was one, or the other. Can I have both àt the same time? What
for?

I didn't even know there were 2 cards in that laptop when I bought it. I
only want the HDMI to work properly so I can listen to some music in good
conditions. Why would I want to use the "bad" audio card?

My guess is it goes to the "normal" one, as I barely hear anything with the
volume at 100%. Any other way to know for sure?

Why are there 2 different programs? And how are the other applications
supposed to know which one to use? I have looked at the settings in
GMusicBrowser, RythmBox and VLC and didn't find anything that seems related
to alsa or pulseaudio; so I don't know how to configure these applications.
