hda-verb improvements for Asus Zenbook Pro Duo UX582LR
by Marcel Brouillet 25 Feb '23

25 Feb '23

Hello, I have a Asus Zenbook Pro Duo UX582LR that does not have sound out-of-the box. But with either this : hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774 hda-verb /dev/snd/hwC0D0 0x20 0x500 0x45 hda-verb /dev/snd/hwC0D0 0x20 0x400 0x5289 Or this : hda-verb /dev/snd/hwC0D0 0x20 0x500 0x1b hda-verb /dev/snd/hwC0D0 0x20 0x477 0x4a4b hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf hda-verb /dev/snd/hwC0D0 0x20 0x477 0x74 Then 1. I do get output from the laptop speakers ✅ 2. I do get output through a headset when pluged in (and no sound through speakers) ✅ 3. I do get input from laptop mics, *but far too high gain. *Setting the mic level to 35% in Pulse Audio is roughly good 4. Input *remains from laptop mics even when I plug in headsets* (TRRS jack) I've been OK with this for 18 months, but decided to chip in the time to solve 3 and 4 and make it available to the community. I looked at https://github.com/alsa-project/alsa-tools/tree/master/hda-verb and understand the hda-verb syntax. But *where do I find the verb arguments (strings or the above cryptic 0x477 or 0x400) ?* Do I need to read this 220 pages document ? https://www.intel.com/content/www/us/en/standards/high-definition-audio-spe… *If anyone is willing to direct me to the few verbs to try, and please tell me if there is any risk of killing my sound interface with wrong parameters, a big thank you to you.* Regards, Marcel.

From within the early trigger we are doing a reset of the SERDES unit, but the final status read is on a bad address. Add the missing SERDES unit offset in calculation of the address.

[PATCH] ASoC: adau7118: don't disable regulators on device unbind
by Nuno Sá 24 Feb '23

24 Feb '23

The regulators are supposed to be controlled through the set_bias_level() component callback. Moreover, the regulators are not enabled during probe and so, this would lead to a regulator unbalanced use count.

If it is Desktop Konnekt 6, node offset 0x'ffff'e0a0'103c has the 32 bit value to express the state of phantom powering. If it is 0, disabled, else enabled. Quadlet write asynchronous transaction can change the state, but I have never used MacOs to operate any node in IEEE 1394 bus. I know some developer and user for the craft driver; e.g. * Re: [alsa-devel] Tascam Coding Inquiry * https://lore.kernel.org/alsa-devel/20200108095430.GA16741@workstation/ I think it your help to contact to them. Especially Paul Neyrinck[1] seems to complete his work for the craft driver of Digidesign Digi 002/003 family in MacOS. They are different hardware from yours, while he will help you to execute the simple read/write transaction to a certain offset of it. [1] https://neyrinck.com/ Regards Takashi Sakamoto

[PATCH v6 0/4] Add CS35L41 shared boost feature
by Lucas Tanure 22 Feb '23

22 Feb '23

Valve's Steam Deck uses CS35L41 in shared boost mode, where both speakers share the boost circuit. Add this support in the shared lib, but for now, shared boost is not supported in HDA systems as would require BIOS changes. Based on David Rhodes shared boost patches. Also, fix boost config overwriting in IRQ found in the review and do a small refactor of the code. Changes from V5: - Improved documentation from Cirrrus - All amps use MDSCYN for boost source - Active amp has TX and RX enabled Changes from V4: - Fix Document subject Changes from V3: - Fix wrong code sent - Fix ISO C90 mixed declarations and code Changes from V2: - Drop External boost without VSPK Documentation - Move Shared boost to use values 2 and 3 - Revert back to reg_sequence but reading the value first and only update the necessary bits - Fix bug found by Intel kernel Test Robot Changes from V1: - Fix Documentation patch subject - New patch for External boost without VSPK Documentation - New patch to fix boost IRQ overwriting issue - New patch to refactor IRQ release error code - reinit_completion on pcm_startup - fix DRE switch overwriting - return IRQ_HANDLED in PLL_LOCK case Lucas Tanure (4): ASoC: cs35l41: Only disable internal boost ASoC: cs35l41: Refactor error release code ALSA: cs35l41: Add shared boost feature ASoC: dt-bindings: cirrus,cs35l41: Document CS35l41 shared boost .../bindings/sound/cirrus,cs35l41.yaml | 10 +- include/sound/cs35l41.h | 13 +- sound/pci/hda/cs35l41_hda.c | 6 +- sound/soc/codecs/cs35l41-lib.c | 73 +++++++++- sound/soc/codecs/cs35l41.c | 125 +++++++++--------- sound/soc/codecs/cs35l41.h | 1 + 6 files changed, 157 insertions(+), 71 deletions(-) -- 2.39.2

[PATCH 00/10] ASoC: Initial support for Cirrus Logic CS35L56
by Richard Fitzgerald 22 Feb '23

22 Feb '23

The CS35L56 is a high-performance boosted mono audio amplifier. Supported control interfaces are I2C, SPI or SoundWire. Supported audio interfaces are I2S/TDM or SoundWire. The CS35L56 has a self-booting firmware in ROM, with the ability to patch the firmware and/or apply tunings. Patches #1 to #7 add support to cs_dsp and wm_adsp for self-booting firmware and the ability to apply a .bin file without having to apply a .wmfw. Patch #8 adds the ASoC driver. Patches #9 and #10 add support for this to the Intel sof_sdw machine driver.

I maintain the repository. Linux kernel has driver stack for audio and music unit in IEEE 1394 bus. I maintain the driver stack as well. For example, you can see backport drivers from mainline Linux kernel: * https://github.com/takaswie/snd-firewire-improve/ The repository you found is supplemental one. It provides user space service program to configure DSP functions such as channel strip effects. Besides, they are available in Linux only. As long as I know, no one work to develop craft drivers in MacOS for your device. P.S. I think you use 'Desktop Konnekt 6' or 'Konnekt 8'. Takashi Sakamoto
