I would be very grateful for any help with the following issue.
I have Ubuntu 14.04 nicely installed and running on an old mac mini. I
want to wireless stream video around my home with a Kworld DVD Maker 2
USB video capture card and VLC, like I did nicely for years under
Ubuntu 10.10. Since upgrading, video still works perfectly, but sound
is tricky. I can record sound from the USB device with Audacity
(default settings), but can't play sound from it with VLC or mplayer,
seemingly because no hw:1,0 alsa playback device is being created for
VLC to use, like it used to be under 10.10.
Surely this is fixable as sound is entering the box - I seem to be so
close. Any help much appreciated as it will save good money on
expensive alternatives such as a Slingbox!
Here's what I know.

Ubuntu gnome sound app settings:
These show a "Line In USB 2861 Device" and the Input Level indicator
flickers nicely to show sound is being received.
Info from mplayer:
When I try to run this with commands that worked on the old system, I
get nice video but an "Audio no sound" message.
