Usually this should be in exactly middle, which corresponds to 0dB.
Yep I did. I guess you're tired of stupid support requests. Don't worry I think I know what I'm doing very well. Tried with lots of different model options for the module too, none worked.
Anyway, please show the alsa-info.sh output with --no-upload option. This will tell us more detailed information.
Sure, I'm attaching 2 version. One is by not passing any argument to the module after a fresh boot, the other one is by using model=dell-m42 which should be mine according to my PID. BTW there are lots of bug tickets opened for this card over the net, most related to Ubuntu and kernel > 2.6.24
Thanks, Manuel
I only see the 'Digital Capture Volume' in the no parameters output. You generally need to run 'arecord -f cd foo.wav' to load the digital softvol mixer.
Thanks,

Sorry, ok I did that. With pulseaudio running calling to arecord fails.
Maybe a bug of pulse alsa-plugin I posted today?
Takashi
I just thought it could be pulse. Where's the bug report? I would like to take a look, maybe I can help.
