Btw, for the code modification, I modified model will in patch_realtek.c which works same as the hda-verb command. From: static const struct hda_verb alc260_will_verbs[] = { {0x0f, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_HP}, {0x0b, AC_VERB_SET_CONNECT_SEL, 0x00}, {0x0d, AC_VERB_SET_CONNECT_SEL, 0x00}, {0x0f, AC_VERB_SET_EAPD_BTLENABLE, 0x02}, {0x1a, AC_VERB_SET_COEF_INDEX, 0x07}, {0x1a, AC_VERB_SET_PROC_COEF, 0x3040}, {} }; To: static const struct hda_verb alc260_will_verbs[] = { {0x0f, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_HP}, {0x0b, AC_VERB_SET_CONNECT_SEL, 0x00}, {0x0d, AC_VERB_SET_CONNECT_SEL, 0x00}, {0x0f, AC_VERB_SET_EAPD_BTLENABLE, 0x02}, {0x1a, AC_VERB_SET_COEF_INDEX, 0x07}, {0x1a, AC_VERB_SET_PROC_COEF, 0x3040}, {0x01, AC_VERB_SET_GPIO_MASK, 0x01}, {0x01, AC_VERB_SET_GPIO_DIRECTION, 0x01}, {} };

Hi all, I solved the speaker problem of B1900, and I have you can fix the driver in next alsa release. I use hda-verb tool to enable sound from speaker. Commands as below: sudo hda-verb /dev/snd/hwC0D0 0x01 0x716 0x01 sudo hda-verb /dev/snd/hwC0D0 0x01 0x717 0x01
Perhaps you need to add a new model besides will. Meanwhile, auto detect of headphone inserting is not function, so speaker and headphone don't switch automatically.

The auto-parser require correct pin default
Refer to alc260 General Description
Realtek's proprietary impedance sensing and jack detect techniques allow device loads on inputs and outputs to be auto-detected. All analog IOs are input and output capable. Headphone amplifiers are also integrated at each analog output. All analog IOs can be re-tasked according to user's definitions, or automatically switched to suit the connecting device (Universal Audio Jack®).
Reserve analog mixer architecture is backwards compatible with AC'97
the function is_jack_detectable() has been changed to check AC_DEFCFG_MISC_NO_PRESENCE

I guess Takashi Iwai expect you to provide a pin fixup patch which provide the pin location of the speaker , internal mic, headphone and external mic jack for the auto parser
Refer to #25
Adding micphone detect: $ sudo hda-verb /dev/snd/hwC0D0 0x12 0xF09 0x0 nid = 0x12, verb = 0xf09, param = 0x0 value = 0x800000c8
does impedence sense require some delay to get the accurate reading ? it seem the microphone has a much higher impedenance than your result 0xc8
