OK. You may be able to figure out what influences on the volume by comparing /proc/asound/card0/codec#* file on both models. > Reminds me what also a bit strange: the PCM mixer control only appears after I > have played back something. > > On detail: - unload alsa, rm asound.state, load alsa, alsamixer (no pcm vol) > - play back something, alsamixer (pcm volume is there) > > From there on, it'll always be visible, even after restarts.

The PCM volume is implemented via softvol plugin, and it creates dynamically at the first run.

Check the AD1988B datasheet, and try to assign the different PIN (and corresponding mixer / selector widgets) in init verb and mixer tables. Then, rebuild driver, and try the driver until you get the complete mapping of pin widgets.
