[pvrusb2] s-video input and audio question

[Rick Macdonald]

I think the original poster is confused by calling the red/white audio 
jacks "composite" connectors. The only "composite" jack is the yellow 
RCA jack labeled "Composite Video In" connector. "composite" means the 
three separate Y'PbPr component video signals are mixed (composed) into one.

The device has 4 sources to choose from. The first three are video 
sources; radio of course is audio only.

# cat ctl_input/enum_val
television
s-video
composite
radio

Television and radio get their signals (including audio) from the coax 
connectors on the back near the USB and power connectors. The connectors 
for the other two video sources, labeled "S-Video" and "Composite 
Video", are video only, and get their audio from the red/white 
right/left "Audio In" jacks that are right beside the S-Video and 
Composite Video jacks.

So, the "composite" shown by ctl_input is not an audio source, it's a 
video source.
