Acer Aspire 7520,
/proc/asound/card0/codec#0:Codec: Realtek ALC268
laptop have 3 jacks: line-in, mic-in, output.

Software: fresh install of Ubuntu 12.04, skype

I use Skype mostly to communicate with other players while playing multiplayer games on PS3. I have connected PS3 sound via line-in to get sound back in my headphones.
With command:
pactl load-module module-loopback
I was able to hear the sound coming from line-in on the output jack.
The problem is I can't make Skype to capture mic-input while having line-in sound redirected to the headphones. I can only select one source as a sound input for Skype via PulseAudio Volume Control but then again I am losing line-in monitoring.
Is there any possibility to do both? Or is it simply hardware limited?
