ALSA: usb-audio: Skip volume controls triggers hangup on Dell USB Dock

2016-04-20T05:08:55+00:00

[ Upstream commit adcdd0d5a1cb779f6d455ae70882c19c527627a8 ]

This is Dell usb dock audio workaround.
It was fixed the master volume keep lower.

[Some background: the patch essentially skips the controls of a couple
 of FU volumes.  Although the firmware exposes the dB and the value
 information via the usb descriptor, changing the values (we set the
 min volume as default) screws up the device.  Although this has been
 fixed in the newer firmware, the devices are shipped with the old
 firmware, thus we need the workaround in the driver side.  -- tiwai]

ALSA: hda/realtek - Enable the ALC292 dock fixup on the Thinkpad T460s

2016-04-20T05:08:55+00:00

[ Upstream commit c636b95ec5980345674ad7960a3c67135a84b687 ]

The Lenovo Thinkpad T460s requires the alc_fixup_tpt440_dock as well in
order to get working sound output on the docking stations headphone jack.

Patch tested on a Thinkpad T460s (20F9CT01WW) using a ThinkPad Ultradock
on kernel 4.4.6.

ALSA: hda - fix front mic problem for a HP desktop

2016-04-20T05:08:55+00:00

[ Upstream commit e549d190f7b5f94e9ab36bd965028112914d010d ]

The front mic jack (pink color) can't detect any plug or unplug. After
applying this fix, both detecting function and recording function
work well.

ALSA: usb-audio: Add a quirk for Plantronics BT300

2016-04-20T05:08:50+00:00

[ Upstream commit b4203ff5464da00b7812e7b480192745b0d66bbf ]

Plantronics BT300 does not support reading the sample rate which leads
to many lines of "cannot get freq at ep 0x1". This patch adds the USB
ID of the BT300 to quirks.c and avoids those error messages.

ALSA: usb-audio: Add a sample rate quirk for Phoenix Audio TMX320

2016-04-20T05:03:44+00:00

[ Upstream commit f03b24a851d32ca85dacab01785b24a7ee717d37 ]

Phoenix Audio TMX320 gives the similar error when the sample rate is
asked:
  usb 2-1.3: 2:1: cannot get freq at ep 0x85
  usb 2-1.3: 1:1: cannot get freq at ep 0x2
  ....

Add the corresponding USB-device ID (1de7:0014) to
snd_usb_get_sample_rate_quirk() list.

ALSA: hda - Fix regression of monitor_present flag in eld proc file

2016-04-18T12:51:10+00:00

[ Upstream commit 023d8218ec0dfc30e11d4ec54f640e8f127d1fbe ]

The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI
monitor_present update] covered the missing update of monitor_present
flag, but this caused a regression for devices without the i915 eld
notifier.  Since the old code supposed that pin_eld->monitor_present
was updated by the caller side, the hdmi_present_sense_via_verbs()
doesn't update the temporary eld->monitor_present but only
pin_eld->monitor_present, which is now overridden in update_eld().

The fix is to update pin_eld->monitor_present as well before calling
update_eld().

Note that this may still leave monitor_present flag in an inconsistent
state when the driver repolls, but this is at least the old behavior.
More proper fix will follow in the later patch.

The Microsoft HD-5001 webcam microphone does not support sample rate
reading as the HD-5000 one.
This results in dmesg errors and sound hanging with pulseaudio.

ALSA: hda - Fix forgotten HDMI monitor_present update

[ Upstream commit bd48128539ab89986b24ad08ecd3e027dd1993a1 ]

We forgot to copy monitor_present value when updating the ELD
information.  This won't change the ELD retrieval and the jack
notification behavior, but appears only in the proc output.   In that
sense, it's no fatal error, but a bug is a bug is a bug.

ALSA: hda - Split ELD update code from hdmi_present_sense()

2016-04-18T12:51:04+00:00

[ Upstream commit e90247f9fceeebe5bdaac2d87e301e73bae9bc1f ]

This is a preliminary patch for the later change to support ELD/jack
handling with i915 audio component.  This splits the ELD update code
from hdmi_present_sense() so that it can be called from other places.

Just a code refactoring, no functional change.

ALSA: usb-audio: Add sanity checks for endpoint accesses

2016-04-18T12:50:59+00:00

[ Upstream commit 447d6275f0c21f6cc97a88b3a0c601436a4cdf2a ]

Add some sanity check codes before actually accessing the endpoint via
get_endpoint() in order to avoid the invalid access through a
malformed USB descriptor.  Mostly just checking bNumEndpoints, but in
one place (snd_microii_spdif_default_get()), the validity of iface and
altsetting index is checked as well.
