Mplayer : Audio Input as "Audio In" or say the sound card In-jack

[Abhishek Sharma <sharma abhisharma gmail com>]

How can I configure Mplayer to take audio input from the "Audio In"
port of the sound card.

Actually I want to play TV on Mplayer and My TV tuner card gives out
audio output as "Audio out" , I have a connector lead which connects
this "Audio Out" of TV card to "Audio In" of sound card.  Now I want
Mplayer to play this audio while playing TV.

Thanx!
