Hi Ash,
yes, the alsa settings are the same... at least this is what the amixer contents say! (I've set the controls that affects the recording, such as Analog Capture Volume = 5, Digital Capture Volume = 0, and the various Capture Switch).

There is something I've forgot to set?

Hi Francesco,

Perhaps a silly question but are the alsa settings the same?  I think
the 'amixer' command should dump the current settings.
