[GRLUG] Linux Mint 13 No sound output from Line-in

[moosebriard]

I have a Windoze computer running television from a Hauppage TV tuner card.
I output from the Speaker (High Definition Audio Device) through a cord
into my Linux Mint 13 box's Line-in port. I have made sure the items
"Master" and "Line" are at 100 in Alsamixer. When I open sound settings and
click the input tab, I see the input level meter fluctuating. The speaker
test from the Linux box works, but no output from the Line-in connector.

I recently upgraded from Mint 12 to 13. The set up worked under Mint 12 for
a long time. I remember messing with it for quite some time until I found
out about Alsamixer when I got it to work last time. Any ideas as to what I
am overlooking?
