If anyone has any objections, please let me know. ------------------ From: Takashi Iwai commit 7a9744cb455e6faa287e148394b4b422a6f3c5c4 upstream. When a driver is set up without the jack detection explicitly (either by passing a model option or via a specific fixup), the pin powermap of IDT/STAC codecs is set up wrongly, resulting in the silence output. It's because of a logic failure in stac_init_power_map(). It tries to avoid creating a callback for the pins that have other auto-hp and auto-mic callbacks, but the check is done in a wrong way at a wrong time. The stac_init_power_map() should be called after creating other jack detection ctls, and the jack callback should be created only for jack-detectable widgets. This patch fixes the check in stac_init_power_map() and its callee at the right place, after snd_hda_gen_build_controls().
