alsa-project/alsa-ucm-conf issue #325 was opened from myrkr: I'm currently testing an update of alsa-ucm-conf from version v1.2.5.1 to version v1.2.9 and noticed a regression. Kernel: v6.1.34 alsa-lib: v1.2.6.1 pulseaudio: 14.2 I use a Lenovo T14G1 with an HDMI monitor connected via USB-C (but the monitor is not in use by Xorg). I want to use the built-in speaker and microphone of the device. Before the update I got the following output from "pactl list": [pactl-before.log](https://github.com/alsa-project/alsa-ucm-conf/files/11788… ``` Card #0 Name: alsa_card.pci-0000_00_1f.3-platform-skl_hda_dsp_generic Driver: module-alsa-card.c Owner Module: 1 Properties: alsa.card = "0" alsa.card_name = "sof-hda-dsp" alsa.long_card_name = "LENOVO-20S1S19N00-ThinkPadT14Gen1" device.bus_path = "pci-0000:00:1f.3-platform-skl_hda_dsp_generic" sysfs.path = "/devices/pci0000:00/0000:00:1f.3/skl_hda_dsp_generic/sound/card0" device.bus = "pci" device.vendor.id = "8086" device.vendor.name = "Intel Corporation" device.product.id = "02c8" device.product.name = "Comet Lake PCH-LP cAVS" device.string = "0" device.description = "Comet Lake PCH-LP cAVS" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" Profiles: HiFi: Play HiFi quality Music (sinks: 4, sources: 2, priority: 8000, available: yes) off: Off (sinks: 0, sources: 0, priority: 0, available: yes) Active Profile: HiFi Ports: [Out] HDMI3: HDMI / DisplayPort 3 Output (type: HDMI, priority: 700, latency offset: 0 usec, not available) Part of profile(s): HiFi [Out] HDMI2: HDMI / DisplayPort 2 Output (type: HDMI, priority: 600, latency offset: 0 usec, not available) Part of profile(s): HiFi [Out] HDMI1: HDMI / DisplayPort 1 Output (type: HDMI, priority: 500, latency offset: 0 usec, not available) Part of profile(s): HiFi [Out] Speaker: Speaker (type: Speaker, priority: 100, latency offset: 0 usec, availability unknown) Part of profile(s): HiFi [Out] Headphones: Headphones (type: Headphones, priority: 200, latency offset: 0 usec, not available) Part of profile(s): HiFi [In] Mic2: Headphones Stereo Microphone (type: Mic, priority: 200, latency offset: 0 usec, not available) Part of profile(s): HiFi [In] Mic1: Digital Microphone (type: Mic, priority: 100, latency offset: 0 usec, availability unknown) Part of profile(s): HiFi ``` On this cards the ports `Speaker` and `Mic1` are currently selected and usable.

I did a `git bisect` and found out that reverting the following commit from v1.2.7 solves the problem: ``` commit e2cfda5b53f4718f1128fb4df75ec8fb7274d36b Author: Jaroslav Kysela <perex(a)perex.cz> Date: Mon May 23 13:33:24 2022 +0200 HDMI - use new Macro syntax Signed-off-by: Jaroslav Kysela <perex(a)perex.cz> ``` Issue URL : https://github.com/alsa-project/alsa-ucm-conf/issues/325 Repository URL: https://github.com/alsa-project/alsa-ucm-conf

[PATCH v4 1/3] ASoC: Add support for Loongson I2S controller
by YingKun Meng 19 Jun '23

19 Jun '23

From: Yingkun Meng <mengyingkun(a)loongson.cn> Loongson I2S controller is found on 7axxx/2kxxx chips from loongson, it is a PCI device with two private DMA controllers, one for playback, the other for capture. The driver supports the use of DTS or ACPI to describe device resources.

ucm2: PinePhone: use "Mix Mono" routing for earpiece
by GitHub pull_request - opened 18 Jun '23

18 Jun '23

alsa-project/alsa-ucm-conf pull request #324 was opened from a-wai: The earpiece speaker is a mono device, using only a single channel (in our case, the left one) from the DA0 output. This causes loss of information as the right channel is completely discarded when playing stereo audio. In order to avoid this issue, set `AIF1 DA0 Stereo Playback Route` to `Mix Mono` when using the "Earpiece" output port (and only in this case).

alsa-project/alsa-utils pull request #220 was edited from brentlu: Current alsatplg supports only cardinal clock source without m/n divider. Code in SOF ssp driver is ported here to implement the divider function. I tested the code on ADL brya device with following setting: MCLK: 19.2MHz BCLK: 3.072Mz (m 24 n 25) PR of topology is here: https://github.com/thesofproject/sof/pull/7826 Request URL : https://github.com/alsa-project/alsa-utils/pull/220 Patch URL : https://github.com/alsa-project/alsa-utils/pull/220.patch Repository URL: https://github.com/alsa-project/alsa-utils

Mixer settings faulty on M-Audio C400 (usb) after suspend until they're touched in alsamixer
by GitHub issues - opened 17 Jun '23

17 Jun '23

alsa-project/alsa-lib issue #331 was opened from ri0t: I don't know if this is the right place to report it, but: * I do a suspend and resume on my machine * Now, my mixer settings for my M-Audio C400 usb-soundcard are set to output all signals on the first pcm out * alsamixer doesn't reflect the true settings of the mixer, instead it shows the last used (correct, or wanted) settings * Once i touch one of the mixer controls in alsamixer, the settings get set to the correct values (+ that change i did) * This repeats every suspend/resume-cycle I've observed this on Debian Bullseye and now on NixOS 23.05. Thanks in advance, even if you point me to a better place to post this. I can supply more debug info, once i know what you need, but the upload from alsa-info to www.alsa-project.org failed somehow without providing me a url.

[PATCH 1/4] ASoC: max98388: fix unused function warnings
by Arnd Bergmann 17 Jun '23

17 Jun '23

From: Arnd Bergmann <arnd(a)arndb.de> The PM functions are never referenced when CONFIG_PM_SLEEP is disabled: sound/soc/codecs/max98388.c:854:12: error: unused function 'max98388_suspend' [-Werror,-Wunused-function] static int max98388_suspend(struct device *dev) ^ sound/soc/codecs/max98388.c:864:12: error: unused function 'max98388_resume' [-Werror,-Wunused-function] static int max98388_resume(struct device *dev) Fix this by using the modern SYSTEM_SLEEP_PM_OPS() macro in place of the deprecated SET_SYSTEM_SLEEP_PM_OPS() version, and use pm_sleep_ptr() to hide the entire structure as well. On a related note, the of_match_ptr() and ACPI_PTR() macros have the same problem and would cause the device id table to be unused when the driver is built-in and the respective subsystems are disabled. This does not cause warnings unless -Wunused-const-variable is passed to the compiler, but it's better to just not use the macros at all here.
