[PATCH] ALSA: hda/hdmi: Add Intel silent stream support
by Harsha Priya 25 Jun '20

25 Jun '20

External HDMI receivers have analog circuitry that needs to be powered-on when exiting standby, and a mechanism to detect PCM v. IEC61937 data. These two steps take time and up to 2-3 seconds of audio may be muted when starting playback. Intel hardware can keep the link active with a 'silent stream', so that the receiver does not go through those two steps when valid audio is transmitted. This mechanism relies on an info packet and preventing the codec from going to D3, which will increase the platform static power consumption. The info packet assumes a basic 2ch stereo, and the silent stream is enabled when connecting a monitor. In case of format changes the detection of PCM v. IEC61937 needs to be re-run. In this case there is no way to avoid the 2-3s mute. The silent stream is enabled with a Kconfig option, as well as a kernel parameter should there be a need to override the build time default. Silent stream is supported in Intel platforms Skylake and beyond. Tested HDMI plug-out plug-in from Intel Cometlake based Chromebook connected to few different monitors.

[PATCH] ALSA: hda - let hs_mic be picked ahead of hp_mic
by Hui Wang 25 Jun '20

25 Jun '20

We have a Dell AIO, there is neither internal speaker nor internal mic, only a multi-function audio jack on it. Users reported that after freshly installing the OS and plug a headset to the audio jack, the headset can't output sound. I reproduced this bug, at that moment, the Input Source is as below: Simple mixer control 'Input Source',0 Capabilities: cenum Items: 'Headphone Mic' 'Headset Mic' Item0: 'Headphone Mic' That is because the patch_realtek will set this audio jack as mic_in mode if Input Source's value is hp_mic. If it is not fresh installing, this issue will not happen since the systemd will run alsactl restore -f /var/lib/alsa/asound.state, this will set the 'Input Source' according to history value. If there is internal speaker or internal mic, this issue will not happen since there is valid sink/source in the pulseaudio, the PA will set the 'Input Source' according to active_port. To fix this issue, change the parser function to let the hs_mic be stored ahead of hp_mic.

[PATCH 0/5] ASoC: add dailink .exit() callback
by Pierre-Louis Bossart 25 Jun '20

25 Jun '20

While looking at reboot issues and module load/unload tests, I found out some resources allocated in the dailink .init() callback are not properly released - there is no existing mechanism in the soc-core to do so. The addition of a dailink .exit() callback seems to be the simplest solution overall. It can be argued that the existing machine platform device .remove() callback can also perform the necessary cleanups, however as shown in the last two examples this might require a loop to identify components whereas the dailink .exit() already has all the necessary information to revert the actions done in the .init() step. Changes since RFC: Better commit messages and explanations rt5682 cases with snd_soc_component_set_jack() called in the .exit() Fred Oh (2): ASoC: intel: sof_rt5682: move disabling jack to dai link's exit() ASoC: intel: cml_rt1011_rt5682: disable jack in dailink .exit() Pierre-Louis Bossart (3): ASoC: soc-link: introduce exit() callback ASoC: Intel: bdw-rt5677: fix module load/unload issues ASoC: Intel: kbl-rt5660: use .exit() dailink callback to release gpiod include/sound/soc-link.h | 1 + include/sound/soc.h | 3 +++ sound/soc/intel/boards/bdw-rt5677.c | 18 ++++++++++++++-- sound/soc/intel/boards/cml_rt1011_rt5682.c | 8 ++++++++ sound/soc/intel/boards/kbl_rt5660.c | 17 +++++++++++++-- sound/soc/intel/boards/sof_rt5682.c | 24 ++++++++-------------- sound/soc/soc-core.c | 3 +++ sound/soc/soc-link.c | 6 ++++++ 8 files changed, 60 insertions(+), 20 deletions(-) base-commit: 39853b1438bf9b07349c8c44b48f6c2eda6f8840 -- 2.20.1

Hello This series fixes issues tih the shut-down gpio device tree allocation and a code format issue found. While working on a project slot programming for the tx and rx paths needed to be enabled. In addition the vsense slot programming needed to be configurable and not directly a simpler adder to the isense slot. Finally the yaml conversion patch was moved to be the last patch in the series so that the fixes can be applied and the yaml can be reviewed appropriately and does not hold up the rest of the fixes.
