I every do often change my default card... I have only these two lines
(if I grep out all that is commented out) in my:
$ cat ~/.asoundrc | grep -v '^#'  

pcm.!default { type hw card 1 }
ctl.!default { type hw card 1 }

and sometimes I need to set it to 0, sometimes to 1 (depending of the
update of the system and where the old Hauppauge HVR3000's audio, or the
MBO's Intel HD Audio end up...

So this below is what I somehow practice since long:

That does give the option to choose the card. But it's only one of the
two, the Hauppauge or the Intel HD...

Starting alsamixer and hitting F3 should be where to look for. And I
don't see anything the changing of which gives me audio to work in
Firefox...

I have all built in the kernel. I do have audio, such as with MPlayer or
with Vlc, just I don't have audio in Firefox.

It appears to be basically the same info as in your kind explanation...

But this is now getting way more than 15 minutes... I will try to find
more time, still, but not hours, for this issue...

No, it doesn't. And the issue is not solved yet...
