New information!   (I presume the same will reproduce on my
SL 6.1 machine).

The following actually *worked* on the my Fedora Core 15 live CD 32 bit.
Pulse Audio was running:

         arecord -d 5 -f cd -t wav -D front foobar.wav

Booting back into CentOS 5.7, both "-D front" and "-D default"
do not work (no joy).

Now this is funny. In CentOS 5.7, I have two "front" devices:

$ arecord -L

front:CARD=ESB2,DEV=0
Intel ESB2, Intel ESB2
Front speakers

front:CARD=NVidia
HDA NVidia
Front speakers

I think if I can figure out how to tell "arecord" I want the
"front" on the ESB2, not the nVidia HDMI, I can get this thing to work!

Anyone have any ideas?

Many thanks,
-T
