ALSA: hda - Fix mic issues on Acer Aspire E1-472

2016-03-09T18:15:25+00:00

[ Upstream commit 02322ac9dee9aff8d8862e8d6660ebe102f492ea ]

This patch applies the microphone-related fix created for the Acer
Aspire E1-572 to the E1-472 as well, as it uses the same Realtek ALC282
CODEC and demonstrates the same issues.

This patch allows an external, headset microphone to be used and limits
the gain on the (quite noisy) internal microphone.

ALSA: hdsp: Fix wrong boolean ctl value accesses

2016-03-09T18:15:19+00:00

[ Upstream commit eab3c4db193f5fcccf70e884de9a922ca2c63d80 ]

snd-hdsp driver accesses enum item values (int) instead of boolean
values (long) wrongly for some ctl elements.  This patch fixes them.

ALSA: hdspm: Fix zero-division

2016-03-09T18:15:19+00:00

[ Upstream commit c1099c3294c2344110085a38c50e478a5992b368 ]

HDSPM driver contains a code issuing zero-division potentially in
system sample rate ctl code.  This patch fixes it by not processing
a zero or invalid rate value as a divisor, as well as excluding the
invalid value to be passed via the given ctl element.

ALSA: hda - Fix headset support and noise on HP EliteBook 755 G2

2016-03-09T18:15:09+00:00

[ Upstream commit f883982dc1b117f04579f0896821cd9f2e397f94 ]

HP EliteBook 755 G2 with ALC3228 (ALC280) codec [103c:221c] requires
the known fixup (ALC269_FIXUP_HEADSET_MIC) for making the headset mic
working.  Also, it suffers from the loopback noise problem, so we
should disable aamix path as well.

ALSA: hda - Fixup speaker pass-through control for nid 0x14 on ALC225

2016-03-09T18:15:08+00:00

[ Upstream commit 2ae955774f29bbd7d16149cb0ae8d0319bf2ecc4 ]

On one of the machines we enable, we found that the actual speaker volume
did not always correspond to the volume set in alsamixer. This patch
fixes that problem.

This patch was orginally written by Kailang @ Realtek, I've rebased it
to fit sound git master.

[ Upstream commit 7cb32ae09a6490c27bc3c110ee42d808a5670142 ]

commit 3b43b71f05d3ecd01c4116254666d9492301697d upstream.

After login to the desktop on Dell Inspiron 3162,
there's a very loud background noise comes from the builtin speaker.
The noise does not go away even if the speaker is muted.

The noise disappears after using the aamix fixup.

ALSA: hda - Add mic mute hotkey quirk for Lenovo ThinkCentre AIO

2016-03-09T18:15:05+00:00

[ Upstream commit 3694cb2947db50753caf432db067487eafae7b9b ]

The Lenovo ThinkCenter AIO uses Line2 (NID 0x1b) to implement the
micmute hotkey, here we register an input device and use Line2 unsol
event to collect the hotkey pressing or releasing.

In the meanwhile, the micmute led is controlled by GPIO2, so we
use an existing function alc_fixup_gpio_mic_mute_hook() to control
the led.

[Hui: And there are two places to register the input device, to make
the code simple and clean, move the two same code sections into a
function.]

ALSA: hda - Fixing speaker noise on the two latest thinkpad models

2016-03-09T18:15:05+00:00

[ Upstream commit 23adc192b862b69ad80a40bd5206e337f41264ac ]

We have two latest thinkpad laptop models which are all based on the
Intel skylake platforms, and all of them have the codec alc293 on
them. When the machines boot to the desktop, an greeting dialogue
shows up with the notification sound. But on these two models, there
is noise with the notification sound. We have 3 SKUs for each of
the models, all of them have this problem.

So far, this problem is only specific to these two thinkpad models,
we did not find this problem on the old thinkpad models with the
codec alc293 or alc292.

A workaround for this problem is disabling the aamix.
