This is the information about the Line in Configuration

   Simple mixer control 'Line',0
   Capabilities: pvolume pswitch cswitch cswitch-exclusive
   Capture exclusive group: 0
   Playback channels: Front Left - Front Right
   Capture channels: Front Left - Front Right
   Limits: Playback 0 - 31
   Front Left: Playback 25 [81%] [on] Capture [on]
   Front Right: Playback 25 [81%] [on] Capture [on]

The modules are loaded as following
   modprobe saa7134 card=3 tuner=39
   modprobe saa7134-oss

And create the following devices with index = 1
   ls -l /dev | grep audio
   crw-rw---- 1 root audio    14,  12 2006-08-01 13:03 adsp
