All pins get set to D3 afterwards anyway, so as long as this implementation does not cause regressions anywhere, I'll try this first out of simplicity. > 1) There is a wrong AC_VERB_SET_CONNECT_SEL setting.

The 0x17 node is not used because there is a more direct path ( 0x19 -> 0x10 instead of 0x19 -> 0x17 -> 0x10 ). In some codecs, not using the mixer node gives slightly better audio quality, so therefore we use this strategy by default. Is it causing any practical problems for you? > 2) I don't know how to explain it but there is a wrong PCM level.

As far as I can see, this corresponds to a "Speaker" and a "Master" slider, or "Headphones" and "Master" if you have headphones plugged in. Start "alsamixer" in a terminal. (see https://wiki.ubuntu.com/Audio/Alsamixer for keys you can use.) Fiddle around with this, i e, move the slider in the sound settings GUI and see the alsamixer GUI bars moving. Or change things in the alsamixer GUI and notice what results it has on the actual output volume. It seems to me like either of the "Speaker" or "Master" sliders are not working properly, or maybe "Headphones" control Speakers or something otherwise strange here.
