Oh, thanks! That's really explain our behaviour... I'll follow your instructions in order to disable the power_save_node flag.

Ah, that explains why the driver doesn't work. As default, the driver does the dynamic codec power-down depending on the jack detection. And in your case, it's soldered. That said, it's no real "bug" in the driver, but it's rather a special use case. As already mentioned, the power_save_node flag can be turned off via codec hints. You can write a codec "patch" file containing the lines like the following: [codec] 0x10134207 0x10134207 0 [hint] power_save_node = no and put it in e.g. /lib/firmware/alsa/cs4207-hack, and pass it via a module option, e.g. add the following line options snd-hda-intel patch=,alsa/cs4207-hack in any /etc/modprobe.d/*.conf file. The comma (,) before "alsa/cs4207-hack" is no typo, it means to pass to the secondary card. The brief instruction is found in Documentation/sound/hd-audio/notes.rst.
