2009-10-11ALSA: HDA VIA: Add smart5.1 function.Lydia Wang
Smart 5.1 is for 3-jacks model, to reuse input pins as outputs. While off, they act as "line out" / "line in" / "mic in". While on, they acts as "line out" / "back left/right" / "center/lfe".

2009-10-10ALSA: ice1724: Fix surround on Chaintech AV-710Robert Hancock
Fix the num_total_dacs setting for Chaintech AV710. The existing comment that only PSDOUT0 is connected is correct, but since the card is using packed AC97 mode to send 6 channels to the codec, num_total_dacs should be set to 6 and not 2. This allows 6-channel surround to work. Also clarify a comment regarding the additional WM8728 codec on this card (it's connected to the SPDIF output and always receives the same data).

2009-10-09ASoC: TPA6130A2 amplifier driverPeter Ujfalusi
Driver for Texas Instruments TPA6130A2 stereo headphone amplifier. The driver provides playback gain control and also pre-defined DAPM_HP widgets and DAPM routings for power management. The DAPM_HP widget names are: "TPA6130A2 Headphone Left" "TPA6130A2 Headphone Right" From soc machine drivers to use with the tpa6130a2 amplifier, the tpa6130a2_add_controls has to be called, which adds the alsa controls and the DAPM routing needed for the tpa6130a2. After that the machine driver can connect the codec's output with 'TPA6130A2 Left' and 'TPA6130A2 Right': {"TPA6130A2 Left", NULL, "CODEC LEFT OUT"}, {"TPA6130A2 Right", NULL, "CODEC RIGHT OUT"}, Internally the left and right channels are powered separately. When none of the channels are needed the amplifier is powered down: hard power: valid GPIO number is passed within platform data soft power: Using the software shutdown of the amplifier Signed-off-by: Peter Ujfalusi <peter.ujfalusi@nokia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-10-09ALSA: hda - Add full rates/formats support for Nvidia HDMITakashi Iwai
Allow Nvidia HDMI to support more possible sample rates and formats. At best, the really supported rates and formats should be determined together with the negotiation with the HDMI receiver, but it's currently not implemented yet (Nvidia stuff seems incompatible with HDMI 1.3 standard in this regard). As a compromise, we enable all bits, assuming that all recent devices do support such rates/formats. Tested-by: Alan Alan <alanwww1@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Increase the default and maximum PCM buffer prellocation size for ice1724's SPDIF and independent stereo pair outputs to 256K, which is the hardware's maximum supported size.

MIXER to PCM type * PLEASE NOTE - this change requires the corresponding update of envy24control for ice1712 - kind of an ABI change. * The "Multi Track Peak" control is read-only level meters indicator. * The control is VERY confusing to most users since it is currently displayed in regular mixers. E.g. alsamixer ignores its read-only status and allows changing the levels with keys which makes no sense.

2009-10-06sound: via82xx: move DXS volume controls to PCM interfaceClemens Ladisch
The "VIA DXS" controls are actually volume controls that apply to the four PCM substreams, so we better indicate this connection by moving the controls to the PCM interface. Commit b452e08e73c0e3dbb0be82130217be4b7084299e in 2.6.30 broke the restoring of these volumes by "alsactl restore" that most distributions use; the renaming in this patch cures that regression by preventing alsactl from applying the old, wrong volume levels to the new controls. http://bugzilla.kernel.org/show_bug.cgi?id=14151 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=532613 Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-10-05ALSA: hda - Fix invalid initializations for ALC861 auto modeTakashi Iwai
The recent auto-parser doesn't work for machines with a single output with ALC861, such as Toshiba laptops, because alc_subsystem_id() sets the hp_pins[0] while it's listed in line_outs[0]. This ends up with the doubled initialization of the same mixer widget, and it mutes the DAC route because hp_pins has no DAC assigned. To fix this problem, just check spec->autocfg.hp_outs and speaker_outs so that they are really detected pins.
