[PATCH] ASoC: SOF: Intel: hda: enable async suspend
by Ranjani Sridharan 04 Mar '21

04 Mar '21

The skylake driver disabled async suspend to prevent disabling the DSP before the card was suspended during system suspend. This code was carried over to the SOF driver. But, there is no risk of the DSP getting disabled before the card is suspended with the SOF driver. Therefore, it is safe to enable async suspend and thereby optimize the system resume time.

[PATCH] ALSA: usb: Add Plantronics C320-M USB ctrl msg delay quirk
by John Ernberg 03 Mar '21

03 Mar '21

The microphone in the Plantronics C320-M headset will randomly fail to initialize properly, at least when using Microsoft Teams. Introducing a 20ms delay on the control messages appears to resolve the issue. Link: https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1065 Tested-by: Andreas Kempe <kempe(a)lysator.liu.se> Signed-off-by: John Ernberg <john.ernberg(a)actia.se> --- Note: Microsoft Teams is the only application tests have been performed with and no other kinds of investigations have been performed, like USB packet logging. Originally reported as a possible PulseAudio issue, where it was suggested to try a delay quirk in the kernel. If other tests should be performed, please let me know which tests and I will try to do them. All testing was done on 5.10, patch was then applied on sound.git master for submission I did not register to the mailing lists, please keep me CC on any comments.

[PATCH 0/4] ALSA: hda/cirrus: Add support for CS8409 HDA bridge and CS42L42 companion codec.
by Vitaly Rodionov 03 Mar '21

03 Mar '21

Dell's laptops Inspiron 3500, Inspiron 3501, Inspiron 3505 are using Cirrus Logic CS8409 HDA bridge with CS42L42 companion codec. The CS8409 is a multichannel HD audio routing controller. CS8409 includes support for four channels of digital microphone data and two bidirectional ASPs for up to 32 channels of TDM data or 4 channels of I2S data. The CS8409 is intended to be used with a remote companion codec that implements high performance analog functions in close physical proximity to the end-equipment audio port or speaker driver. The CS42L42 is a low-power audio codec with integrated MIPI SoundWire interface or I2C/I2S/TDM interfaces designed for portable applications. It provides a high-dynamic range, stereo DAC for audio playback and a mono high-dynamic-range ADC for audio capture Stefan Binding (1): ALSA: hda/cirrus: Add Headphone and Headset MIC Volume Control Vitaly Rodionov (3): ALSA: hda/cirrus: Increase AUTO_CFG_MAX_INS from 8 to 18 ALSA: hda/cirrus: Add support for CS8409 HDA bridge and CS42L42 companion codec.

[PATCH] ASoC: SOF: Intel: broadwell: fix mutual exclusion with catpt driver
by Pierre-Louis Bossart 03 Mar '21

03 Mar '21

In v5.10, the "haswell" driver was replaced by the "catpt" driver, but the mutual exclusion with the SOF driver was not updated. This leads to errors with card names and UCM profiles not being loaded by PulseAudio. This fix should only be applied on v5.10-stable, the mutual exclusion was removed in 5.11.

[PATCH v2 0/5] soundwire: qcom: various improvements
by Srinivas Kandagatla 03 Mar '21

03 Mar '21

Thanks for reviewing v1 of this patchset! During testing SoundWire controller on SM8250 MTP, we found few issues like all the interrupts are not handled, all transport parameters are not read from device tree. Other major issue was register read/writes which was interrupt based was an overhead and puts lot of limitation on context it can be used from. With previous approach number of interrupts generated after enumeration are around 130: $ cat /proc/interrupts | grep soundwire 21: 130 0 0 0 0 0 0 0 GICv3 234 Edge soundwire after this patch they are just 3 interrupts $ cat /proc/interrupts | grep soundwire 21: 3 0 0 0 0 0 0 0 GICv3 234 Edge soundwire So this patchset add various improvements to the existing driver to address above issues. Tested it on SM8250 MTP with 2x WSA881x speakers, HeadPhones on WCD938x via lpass-rx-macro and Analog MICs via lpass-tx-macro. Also tested on DragonBoard DB845c with 2xWSA881x speakers. Changes since v1: - changed bgp_count to blk_group_count as suggested by Pierre - used version raw value as suggested by VKoul - updated read fifo logic and interrupt handling to do while() - renamed some of the variable to make reading easy! - removed patch that parses version Srinivas Kandagatla (5): soundwire: qcom: add support to missing transport params soundwire: qcom: set continue execution flag for ignored commands soundwire: qcom: start the clock during initialization soundwire: qcom: update register read/write routine soundwire: qcom: add support to new interrupts drivers/soundwire/qcom.c | 438 ++++++++++++++++++++++++++++++--------- 1 file changed, 335 insertions(+), 103 deletions(-) -- 2.21.0
