ALSA: hda - Don't set indep_hp flag for old AD codecs

2014-02-06T19:34:10+00:00

commit cbd209f41ea5f39394de5c1fe2dd9aa54a9c5744 upstream.

Some old AD codecs don't like the independent HP handling, either it
contains a single DAC (AD1981) or it mandates the mixer routing
(AD1986A).  This patch removes the indep_hp flag for such codecs.

ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabled

2014-02-06T19:34:04+00:00

commit 75fae117a5dbde5ab984fa5c60705758cfbc6433 upstream.

Commit 384a48d71520 "ALSA: hda: HDMI: Support codecs with fewer cvts
than pins" dynamically enabled each pin widget's PIN_OUT only when the
pin was actively in use. This was required on certain NVIDIA CODECs for
correct operation. Specifically, if multiple pin widgets each had their
mux input select the same audio converter widget and each pin widget had
PIN_OUT enabled, then only one of the pin widgets would actually receive
the audio, and often not the one the user wanted!

However, this apparently broke some Intel systems, and commit
6169b673618b "ALSA: hda - Always turn on pins for HDMI/DP" reverted the
dynamic setting of PIN_OUT. This in turn broke the afore-mentioned NVIDIA
CODECs.

This change supports either dynamic or static handling of PIN_OUT,
selected by a flag set up during CODEC initialization. This flag is
enabled for all recent NVIDIA GPUs.

ALSA: hda - add headset mic detect quirks for another Dell laptop

2014-02-06T19:34:04+00:00

commit 5e87d5807110afd6bd659e1b98929fab43f3732f upstream.

When we plug a 3-ring headset on the Dell machine (Vendor ID:
0x10ec0255, Subsystem ID: 0x1028064d), the headset mic can't be
detected, after apply this patch, the headset mic can work well.

ALSA: hda - Fix silent output on MacBook Air 1,1

2014-02-06T19:34:04+00:00

commit e7729a415315fcd9516912050d85d5aaebcededc upstream.

Similarly to other Apple products, MBA 1,1 needs a specific quirk.
Pin 0x18 must be set to VREF_50 to have sound output.  This was no
longer done since commit 1a97b7f, resulting in a mute built-in speaker.

This patch corrects the regression by creating a fixup for the MBA 1,1.

ALSA: bits vs bytes bug in snd_card_create()

2014-02-06T19:34:04+00:00

commit 4c3773eda49c872a3034382f8ec3080002e715bf upstream.

The test here is intended intended to prevent shift wrapping bugs when
we do "1U << idx2".  We should consider the number of bits in a u32
instead of the number of bytes.

ALSA: hda - add headset mic detect quirks for some Dell machines

2014-02-06T19:34:04+00:00

commit c48ae0ab3790efba2dfb1a4709c0ef8da024de1a upstream.

When we plug a 3-ring headset on some Dell machines, the headset
mic can't be detected, after apply this patch, the headset mic
can work well on all those machines.

On the machine with the Subsytem ID 0x10280610, if we use
ALC269_FIXUP_DELL1_MIC_NO_PRESENCE, the headset mic can be
detected and work well, but the sound can't be outputed via
headphone anymore, use ALC269_FIXUP_DELL3_MIC_NO_PRESENCE
can fix this problem.

ALSA: hda - automute via amp instead of pinctl on some AIO models

2014-02-06T19:34:03+00:00

commit 493a52a9b6645f61954580c7d4bd52fa62110934 upstream.

On some AIO (All In One) models with the codec alc668
(Vendor ID: 0x10ec0668) on it, when we plug a headphone into the jack,
the system will switch the output to headphone and set the speaker to
automute as well as change the speaker Pin-ctls from 0x40 to 0x00,
this will bring loud noise to the headphone.

I tried to disable the corresponding EAPD, but it did not help to
eliminate the noise.

According to Takashi's suggestion, we use amp operation to replace the
pinctl modification for the automute, this really eliminate the noise.

ALSA: Enable CONFIG_ZONE_DMA for smaller PCI DMA masks

2014-02-06T19:34:03+00:00

commit 80ab8eae70e51d578ebbeb228e0f7a562471b8b7 upstream.

The PCI devices with DMA masks smaller than 32bit should enable
CONFIG_ZONE_DMA.  Since the recent change of page allocator, page
allocations via dma_alloc_coherent() with the limited DMA mask bits
may fail more frequently, ended up with no available buffers, when
CONFIG_ZONE_DMA isn't enabled.  With CONFIG_ZONE_DMA, the system has
much more chance to obtain such pages.

ALSA: hda - Don't create duplicated ctls for loopback paths

2014-02-06T19:34:03+00:00

commit 43a8e50a46a4e1dd1451e4a4ffa1f7695fb7d287 upstream.

AD1986A mic pins (0x1d and 0x1f) share the same widget for controlling
the loopback volume/mute, but the generic parser didn't check it.
This ended up with the duplicated controls for the same effect.

This patch adds the check of the duplication for avoiding it.

After this fix, there will be only one control although it affects
both paths; this remaining issue should be fixed later in a different
patch.

commit ed0e0d0617a8dc3d8b82c6e54827f269f2247b07 upstream.

The 3stack pin configs for AD1986A codec had incorrect values that
resulted in broken mic and line-in.
