Added more known names to the vendor id list. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-04-24[ALSA] hda-codec - Add "IEC958 Default PCM" switchTakashi Iwai
Added a new mixer switch to enable/disable the sharing of the default PCM stream with analog and SPDIF outputs. When "IEC958 Default PCM" switch is on, the PCM stream is routed both to analog and SPDIF outputs. This is the behavior in the earlier version. Turning this switch off has a merit for some codecs, though. Some codec chips don't support 24bit formats for SPDIF but only for analog outputs. In this case, you can use 24bit format by disabling this switch. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-04-24[ALSA] hda-codec - More fix-up for auto-configurationTakashi Iwai
In some cases, the BIOS sets up only the HP pins with different assoc and sequence numbers, e.g. on FSC Esprimo with ALC262. This patch adds a fix-up for such a case. When multiple HPs are defined and no line-outs is found, the configurator tries to re-assign some pins from HP list to line-out, judging from the sequence number.

2008-04-24[ALSA] hda-codec - Allow multiple SPDIF devicesTakashi Iwai

AD1986A has a hardware problem that it cannot share a stream with multiple pins properly. The problem occurs e.g. when a volume is changed during playback.

2007-10-16[ALSA] hda-intel - Fix resume logic, when dynamic power managment is onMaxim Levitsky
Comment in hda_intel.c states that 'the explicit resume is needed only when POWER_SAVE isn't set', but this is not true. There is no code that will automaticly power up the codec on resume, but only code that powers it up when user accesses it. So if user leaves a sound playing, codec will not be powered To fix that I check if there are any codecs that should be powered codec->power_count, and if so I power them up together with main controller.

2007-10-16[ALSA] hda-intel - Add POWER_SAVE optionTakashi Iwai
Added CONFIG_SND_HDA_POWER_SAVE kconfig. It's an experimental option to achieve an aggressive power-saving. With this option, the driver will turn on/off the power of each codec and controller chip dynamically on demand. The patch introduces a new module option 'power_save'. It specifies the second of time-out for automatic power-down. As default, it's 10 seconds. Setting 0 means to suppress the power-saving feature. The codec may have analog-input loopbacks, which are usually represented by mixer elements such as 'Mic Playback Switch' or 'CD Playback Switch'. When these are on, we cannot turn off the mixer and the codec chip has to be kept on. For bookkeeping these states, a new codec-callback is introduced. For the bus-controller side, a new callback pm_notify is introduced, which can be used to turn on/off the contoller appropriately. Note that this power-saving might cause slight click-noise at power-on/off. Also, it might take some time to wake up the codec, and might even drop some tones at the very beginning. This seems to be the side-effect of turning off the controller chip. This turn-off of the controller can be disabled by undefining HDA_POWER_SAVE_RESET_CONTOLLER in hda_intel.c.

2007-10-16[ALSA] hda-codec - optimize resume using cachesTakashi Iwai
So far, the driver looked the table of snd_kcontrol_new used for creating mixer elements and forces to call each of its put callbacks in PM resume code. This is too ugly and hackish. Now, the resume is simplified using the codec amp and command register caches. The driver simply restores the values that have been written in the cache table. With this simplification, most codec support codes don't require any special resume callback. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2007-10-16[ALSA] hda-codec - introduce command register cacheTakashi Iwai
This patch adds the cache for codec command registers. snd_hda_codec_write_cache() and snd_hda_sequence_write_cache() do the write operations with caching, which values can be resumed via snd_hda_codec_resume_cache().

2007-10-16[ALSA] hda-intel - Remove invalid __devinitTakashi Iwai
Some functions in hda_codec.c are called from patch ops, which are kept in the codec instance even after initialization. Thus they shouldn't be marked as __devinit. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

2007-10-16[ALSA] hda-codec - Add a generic bind-control helperTakashi Iwai
Added callbacks for a generic bind-control of mixer elements. This can be used for creating a mixer element controlling multiple widgets at the same time. Two macros, HDA_BIND_VOL() and HDA_BIND_SW(), are introduced for creating bind-volume and bind-switch, respectively. It taks the mixer element name and struct hda_bind_ctls pointer, which contains the real control callbacks in ops field and long array for private_value of each bound widget. All widgets have to be the same type (i.e. the same amp capability). Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2007-10-16[ALSA] hda-intel - Add hwdep interfaceTakashi Iwai
Added a hwdep interface for each codec (enabled per kconfig). This interface can be used for reading/writing HD-audio verbs and other purposes as future extensions. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

2007-05-31[ALSA] hda-codec - Fix STAC922x capture boost levelTakashi Iwai
STAC922x provides the capture boost level up to 4, but actually it works only up to 2. Since the range of the mixer is automatically defined from amp-capability bits, we need to override the value beforehand. snd_hda_override_amp_caps() is introduced for this purpose. The function patch_stac922x() calls this for NID 0x12 (Mux Capture Volume). This should fix another recording problem on Intel Macs.

2007-05-16[ALSA] hda-codec - Make the mixer capability check more robustTakashi Iwai
In some cases, mixer elements return -EINVAL because it couldn't obtain proper amp_cap bits. The patch improves the robustness, trying the amp_cap query again in such a case. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2007-05-11[ALSA] Add speaker pin sequencing to hda_codec.c:snd_hda_parse_pin_def_config()Steve Longerbeam
Some verb tables (such as an Asus VT sent by IDT) contain only speaker outs in the default pin configs, and no line-outs. In such a case the speaker sequence numbers have to be used to order the speaker out pins, just as is being done for line-out pins. Then, when speaker-outs are copied to line-outs, the line-outs will be ordered properly.
