OK so type 0 is audio output, so node id 2 and 5 are audio output. Therefore,
in the driver, the:
sorbo_conf_output(sc, 0, 3);
should be replaced with 0, 2 or 0, 5.
The "pins", are type 4 and you need to amplify them. So you need to modify:
sorbo_set_amp(sc, 0, 5, 40);
with:
sorbo_set_amp(sc, 0, 8, 40); // set node id 8 gain 40
sorbo_set_amp(sc, 0, 9, 40); // set node id 9 gain 40
...
sorbo_set_amp(sc, 0, 18, 40); // node id 18.
There is one aditional piece of debug info which might be handy. You need to
make sure that the "pins" are connected to the audio output device. Make enum()
get called as described in the previous mails, then in sorbo_print_widget(), get
rid of 0 && in the type == HDA_PARAM_AUDIO_WIDGET_CAP_TYPE_PIN_COMPLEX. That
is, sorbo_conf_pin() should be called for each pin. This will cause an
additional printf which will tell you which audio output each pin is connected
to [list %x cur %d]. Ideally you want pins to be connected either to 2 or 5 in
your case.
Also, make sure the hardware volume is up, if there are any buttons on the
laptop. =D
