[PATCH] ALSA: hda: cs35l56: Select SERIAL_MULTI_INSTANTIATE
by Simon Trimmer 20 Jun '24

20 Jun '24

The ACPI IDs used in the CS35L56 HDA drivers are all handled by the serial multi-instantiate driver which starts multiple Linux device instances from a single ACPI Device() node. As serial multi-instantiate is not an optional part of the system add it as a dependency in Kconfig so that it is not overlooked.

ALSA volume control ignored for "4c4a:4155 Jieli Technology USB Composite Device"
by GitHub issues - opened 20 Jun '24

20 Jun '24

alsa-project/alsa-lib issue #401 was opened from davidmcnabnz: I just purchased a generic USB audio interface, which shows up in `lsusb` as: ``` 4c4a:4155 Jieli Technology USB Composite Device ``` The device on the whole seems to _simply just work_. But the level control for the stereo capture seems to be completely ignored, both in `alsamixer` and `pavucontrol`. My setup is Debian GNU/Linux 12 (bookworm), standard apt including contrib. General stack is wireplumber and pipewire, implementing JACK via pw-jack and pipewire-pulse. This is working very well for my music work. Lastly, below is a paste of my currently installed packages relevant to ALSA and JACK. Grateful if anyone can advise.

[PATCH v6 0/7] ASoC: codecs: wcd937x: add wcd937x audio codec support
by Mohammad Rafi Shaik 19 Jun '24

19 Jun '24

This patchset adds support for Qualcomm WCD9370/WCD9375 codec. Qualcomm WCD9370/WCD9375 Codec is a standalone Hi-Fi audio codec IC connected over SoundWire. This device has two SoundWire devices, RX and TX respectively supporting 3 x ADCs, ClassH, Ear, Aux PA, 2xHPH, 6 DMICs and MBHC. For codec driver to be functional it would need both tx and rx Soundwire devices to be up and this is taken care by using device component framework and device-links are used to ensure proper pm dependencies. Ex tx does not enter suspend before rx or codec is suspended. This patchset along with other SoundWire patches on the list have been tested on QCM6490 IDP device. Changes since v5: - Remove the string compare in MIC BIAS widget settings as suggested by Srinivas Kandagatla - Fixed Unbalanced pm_runtime_enable! in wcd937x-sdw soundwire slave. Changes since v4: - Removed volatile/read-only registers from defaults list - Added wcd939x_volatile_register() with only volatile registers - Added a wcd939x_readable_register() with read-only and read-write registers, so cache does it's job - Fixed Spurious events for mixer controls and validated with mixer selftest tool - Used TLV instead of enum for ear_pa_gain mixer control - Used enum constraints instead of OneOf in dt-binding patch - Added vdd-px supply property as non optional in dt-binding patch - Reworked and done driver cleanup Changes since v3: - Fixed dt binding check errors. - Added constraints on values in v4-0001 binding patch as suggested by Krzysztof - Change the patch sequence soundwire driver first then codec driver - Added missing .remove soundwire driver function - Reworked and done driver cleanup Changes since v2: - Used common qcom,wcd93xx-common.yaml. removed duplicate properties. - Merged bindings patches "v2-0001" and "v2-0003" in single patch for easy review. - Fixed dt binding check errors. - Added missing "qcom,wcd9375-codec" in v3-0001 dt binding patch. - Added constraints on values in v3-0001 binding patch as suggested by Krzysztof - Fix the typo mistake in v2 cover letter Changes since v1: - Split the patch per driver for easier review as suggested by Krzysztof - Used devm_gpiod_get api to get reset gpio as suggested by Krzysztof Prasad Kumpatla (7): ASoC: dt-bindings: document wcd937x Audio Codec ASoC: codecs: wcd937x-sdw: add SoundWire driver ASoC: codecs: wcd937x: add wcd937x codec driver ASoC: codecs: wcd937x: add basic controls ASoC: codecs: wcd937x: add playback dapm widgets ASoC: codecs: wcd937x: add capture dapm widgets ASoC: codecs: wcd937x: add audio routing and Kconfig .../bindings/sound/qcom,wcd937x-sdw.yaml | 91 + .../bindings/sound/qcom,wcd937x.yaml | 82 + sound/soc/codecs/Kconfig | 20 + sound/soc/codecs/Makefile | 7 + sound/soc/codecs/wcd937x-sdw.c | 1136 +++++++ sound/soc/codecs/wcd937x.c | 3011 +++++++++++++++++ sound/soc/codecs/wcd937x.h | 653 ++++ 7 files changed, 5000 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/qcom,wcd937x-sdw.yaml create mode 100644 Documentation/devicetree/bindings/sound/qcom,wcd937x.yaml create mode 100644 sound/soc/codecs/wcd937x-sdw.c create mode 100644 sound/soc/codecs/wcd937x.c create mode 100644 sound/soc/codecs/wcd937x.h base-commit: d35b2284e966c0bef3e2182a5c5ea02177dd32e4 -- 2.25.1

[PATCH] ASoC: cs35l56: Accept values greater than 0 as IRQ numbers
by Simon Trimmer 19 Jun '24

19 Jun '24

IRQ lookup functions such as those in ACPI can return error values when an IRQ is not defined. The i2c core driver converts the error codes to a value of 0 and the SPI bus driver passes them unaltered to client device drivers. The cs35l56 driver should only accept positive non-zero values as IRQ numbers.

aloop driver introducing glitches
by noman pouigt 18 Jun '24

18 Jun '24

Hello Folks, I wanted to use aloop driver to dump playback audio data to a file in userspace for debugging without data being sent to hardware (just as a debug feature for future use). Command flow is this: 1. aloop capture device is started using below command first: "arec -D hw:0,1 /data/rec.wav &" 2. using aplay, userspace sends the playback data. "aplay -D hw:0,0 /data/test.wav" Using jiffies. Wondering if changing rate_shift (don't know what is that for) will help? However, even in this simple setup I can see aloop driver is corrupting the data and sinetone sent from playback has glitches. I have tried different period sizes as well but nothing worked. Wondering if this is by design i.e. if the aloop driver shouldn't be used for this purpose? Any debug steps will be highly appreciated. Thanks for your help,
