[ltp] Line In recording on an R51

[Peter Lemken]

Hi there,

the R51 only has two audio jacks: Mic In and Headphone out. I haven't figured 
out how to use the input jack for recordings with a non-mic input line.

Is there a soft switch in the audio device that can be used, and if there is, 
how do you do it?

I've been using both audicity with ALSA-support (without artsd) and Krec with 
artsd, but in both cases I have been unable to process an incoming audio 
signal from the input jack.

TIA
