2013-07-29ALSA: hda - Fix invalid multi-io creation on VAIO-Z laptopsTakashi Iwai
VAIO-Z laptops need to use the specific DAC for the speaker output by some unknown reason although the codec itself supports the flexible connection. So we implemented a workaround by a new flag, no_primary_hp, for assigning the speaker pin first. This worked until 3.8 kernel, but it got broken because the driver learned for a better multi-io pin mapping, and not it can assign two mic pins for multi-io. Since the multi-io requires to be the primary output, the hp and two mic pins are assigned in prior to the speaker in the end. Although the machine has two mic pins, one of them is used as a noise- canceling headphone, thus it's no real retaskable mic jack. Thus, at best, we can disable the multi-io assignment and make the parser behavior back to the state before the multi-io. This patch adds again a new flag, no_multi_io, to indicate that the device has no multi-io capability, and set it in the fixup for VAIO-Z. The no_multi_io flag itself can be used generically, added via a helper line, too.

2013-03-07ALSA: hda - Consolidate add_in_jack_modes and add_out_jack_modes hintsTakashi Iwai
There is no big merit to distinguish these two hints. Instead, just have a single flag, add_jack_modes, for creating the jack mode enum ctls for both I/O directions. The hint string parser code is left and translated as add_jack_modes just for keeping compatibility. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-03-07ALSA: hda - Add the generic Headphone Mic featureTakashi Iwai
This patch improves the generic parser code to allow to set up the headphone jack as a mic input. User can enable this feature by giving hp_mic hint string. The former shared hp/mic feature for the single built-in mic is still retained. This detection can be disabled now via hp_mic_detect hint string, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>

This patch adds a new position_fix option value, 4, as a combo mode to use LPIB for playbacks and POSBUF for captures. It's the way recommended by Intel hardware guys. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-09-28ALSA: hda - Allow patching with any vendor/subsystem idsTakashi Iwai
In the ugly real world, there area really broken devices that don't set codec SSID correctly. In such a case, the ID can be random, thus the patching won't work reliably. For applying the patch forcibly to such a device, the driver will skip the vendor and/or subsystem ID checks when zero or a negative number is given in [codec] section.

2010-09-30ALSA: HDA: Add position_fix=3 module option, and refactor related codeDavid Henningsson
What was previously known as via_dmapos_patch, and hard-coded to be used for VIA and ATI controllers, is now configurable through a module option. The background is that some VIA controllers seem to prefer via_dmapos_patch to be turned off.

2010-08-04Documentation: update broken web addresses.Justin P. Mattock
Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

2010-03-26ALSA: hda-intel - remove model=hwio , use probe_only=3 insteadJaroslav Kysela
The probe_only module parameter skips the codec initialization, too. Remove the model=hwio code and use second bit in probe_only to skip the HDA codec reset procedure. Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2010-03-26ALSA: hda-intel - add special 'hwio' model to bypass initializationJaroslav Kysela
Using the 'model=hwio' option, the driver bypasses any codec initialization and the reset procedure for codecs is also bypassed. This mode is usefull to enable direct access using hwdep interface (using hdaverb or hda-analyzer tools) and retain codec setup from BIOS. Signed-off-by: Jaroslav Kysela <perex@perex.cz>
