Audio line-in produces no output

[Alex Janssen]

I've been researching this for several hours, now, and I'm not getting 
anywhere.

I have a DI1501 laptop with the following audio found with lspci:
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
and a desktop with
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio 
Controller (rev 02)
I'm running Ubuntu 9.10 on each.

I remember in 9.04 being able to plug the headphone output of my am/fm 
radio into the line-in jack and listen over the computer speakers.

Now, on either computer, in the Preferences->Sound 
(gnome-volume-control), the input level meter for line-in shows some 
signal level, but I get NO sound from the speakers.

I can't find any references to this specifically and not much for 9.10.  
Most ref's are for earlier(8.04-8.10) versions of Ubuntu.

I hope someone else on the list has run into this.
Could anyone give me a clue?

Alex
