[PATCH AUTOSEL 4.14 10/12] ALSA: hda: generic: change the DAC ctl name for LO+SPK or LO+HP
by Sasha Levin 12 May '21

12 May '21

From: Hui Wang <hui.wang(a)canonical.com> [ Upstream commit f48652bbe3ae62ba2835a396b7e01f063e51c4cd ] Without this change, the DAC ctl's name could be changed only when the machine has both Speaker and Headphone, but we met some machines which only has Lineout and Headhpone, and the Lineout and Headphone share the Audio Mixer0 and DAC0, the ctl's name is set to "Front". On most of machines, the "Front" is used for Speaker only or Lineout only, but on this machine it is shared by Lineout and Headphone, This introduces an issue in the pipewire and pulseaudio, suppose users want the Headphone to be on and the Speaker/Lineout to be off, they could turn off the "Front", this works on most of the machines, but on this machine, the "Front" couldn't be turned off otherwise the headphone will be off too. Here we do some change to let the ctl's name change to "Headphone+LO" on this machine, and pipewire and pulseaudio already could handle "Headphone+LO" and "Speaker+LO".

[PATCH] ASoC: cs42l42: make HSBIAS_SENSE_EN optional
by Vitaly Rodionov 12 May '21

12 May '21

HSBIAS_SENSE_EN configures HSBIAS output current sense through the external 2.21-k resistor. HSBIAS_SENSE is hardware feature to reduce the potential pop noise during the headset plug out slowly. But on some platforms ESD voltage will affect it causing test to fail, especially with CTIA headset type. For different hardware setups, a designer might want to tweak default behavior.

[PATCH 0/9] ASoC: SOF/Intel: fix and remove Sparse warnings
by Pierre-Louis Bossart 12 May '21

12 May '21

We updated our SOF CI settings last week (see below) to use more options for Sparse, and sure enough it detected one nasty single-character bug in one of my previous patches, along with more trivial issues with string/integer sizes and signed/unsigned confusions. export ARCH=x86_64 export CF="-Wsparse-error -Wsparse-all -Wno-bitwise-pointer -Wno-pointer-arith -Wno-typesign -Wnoshadow" make -k sound/soc/sof/ C=2 make -k sound/soc/intel/common/ C=2 make -k sound/soc/intel/boards/ C=2 make -k drivers/soundwire/ C=2 Pierre-Louis Bossart (9): ASoC: SOF: Intel: hda: fix index used in inner loop ASoC: Intel: sof_rt5682: shrink platform_id names below 20 characters ASoC: Intel: sof_cs42l42: shrink platform id below 20 characters ASoC: Intel: bxt_da7219_max98357a: shrink platform_id below 20 characters ASoC: Intel: glk_rt5682_max98357a: shrink platform_id below 20 characters ASoC: Intel: kbl_da7219_max98357a: shrink platform_id below 20 characters ASoC: Intel: sof_da7219_max98373: shrink platform_id below 20 characters ASoC: Intel: sof_sdw: fix signed/unsigned warning ASoC: Intel: soc-acpi: add ull suffix for SoundWire _ADR values sound/soc/intel/boards/bxt_da7219_max98357a.c | 12 +++--- sound/soc/intel/boards/glk_rt5682_max98357a.c | 4 +- sound/soc/intel/boards/kbl_da7219_max98357a.c | 4 +- sound/soc/intel/boards/sof_cs42l42.c | 2 +- sound/soc/intel/boards/sof_da7219_max98373.c | 8 ++-- sound/soc/intel/boards/sof_rt5682.c | 20 +++++----- sound/soc/intel/boards/sof_sdw.c | 2 +- .../intel/common/soc-acpi-intel-adl-match.c | 28 +++++++------- .../intel/common/soc-acpi-intel-bxt-match.c | 2 +- .../intel/common/soc-acpi-intel-cml-match.c | 22 +++++------ .../intel/common/soc-acpi-intel-cnl-match.c | 2 +- .../intel/common/soc-acpi-intel-glk-match.c | 6 +-- .../intel/common/soc-acpi-intel-icl-match.c | 12 +++--- .../intel/common/soc-acpi-intel-jsl-match.c | 6 +-- .../intel/common/soc-acpi-intel-kbl-match.c | 2 +- .../intel/common/soc-acpi-intel-tgl-match.c | 38 +++++++++---------- sound/soc/sof/intel/hda.c | 2 +- 17 files changed, 86 insertions(+), 86 deletions(-) -- 2.25.1
