Péter,
I can't seem to find a Left/Right Digital Loopback the mention of a loop I found is an FM Loop Enable. The following is the dapm_widget enable output from my Gumstix Overo running the 2.6.38 Kernel. Thanks for your help.
Look for the control: amixer -c0
Look for the Left/Right Digital Loopback in the list, and check the value

Hrm, It does seams that the digital loopback is enabled from this. You had only capture running while taken this, right?
