Mismatched volume controls of Sound Blaster X3
by GitHub issues - opened 12 Sep '24

12 Sep '24

alsa-project/alsa-utils issue #273 was opened from buboleck: Hello, Recently I got Creative Sound Blaster X3 (SB1810) as it seemed it works fine with linux. I'm using Gentoo with Plasma desktop (ALSA + Pipewire) and the onboard sound is OK but the SB X3 seems is misbehaving, I found that the volume controls for RearLeft is swapped with Center and RearRight is swapped with the LFE. (Also tried live Ubuntu 24.04 same issue) On the other hand maybe related, I was not able to get stereo upmix working in any way, ALSA upmix does not want to work as also the Pipiwire upmix. Gentoo kernel 6.10.9 alsa-lib-1.2.12 alsa-tools-1.2.11 alsa-utils-1.2.12 alsa-plugins-1.2.12 pyalsa-1.2.12 Issue URL : https://github.com/alsa-project/alsa-utils/issues/273 Repository URL: https://github.com/alsa-project/alsa-utils

Mic mute LED only follows internal rather than selected
by GitHub issues - opened 12 Sep '24

12 Sep '24

alsa-project/alsa-ucm-conf issue #440 was opened from JL2210: I have a laptop keyboard with a key to mute the microphone. Using this key mutes whichever mic is selected as default. However, the light on the key only changes with the internal microphone rather than the active mic. Pressing the key when a headset is plugged in doesn't change the LED, but pressing it without a headset does.

[PATCH v3] ASoC: dt-bindings: renesas,rsnd: add post-init-providers property

At least if rsnd is using DPCM connection on Audio-Graph-Card2, fw_devlink might doesn't have enough information to break the cycle (Same problem might occur with Multi-CPU/Codec or Codec2Codec).

This patch adds support for the primary mi2s interface on devices using SM8250 audio drivers. Tested on SM7150 (xiaomi-davinci).

[PATCH 00/13] ALSA: update sample rate definitions
by Jerome Brunet 11 Sep '24

11 Sep '24

This patchset adds rate definitions for 12kHz, 24kHz and 128kHz. It is follow-up on the series/discussion [0] about adding 128kHz for spdif/eARC support. The outcome was to add 12kHz and 24kHz as well and clean up the drivers that no longer require custom rules to allow these rates. Identifying these drivers is not straight forward, I tried my best but I may have missed some. Those will continue to work anyway so it is not critical. Some drivers using these rates have not been changed on purpose. The reason for this may be: * The driver used other uncommon rates that still don't have a definition so a custom rule is still required. * The constraint structure is used in some other way by the driver and removing it would not help the readability or maintainability. This is the case the freescale asrc drivers for example. There is one change per driver so, if there is a problem later on, it will easier to properly add Fixes tag. The series has been tested with * ARM64 defconfig - spdif 128kHz at runtime. * x86_64 allmodconfig - compile test only Last, the change adding IEC958 definitions has been dropped for this patchset and will be resent separately [0]: https://lore.kernel.org/all/20240628122429.2018059-1-jbrunet@baylibre.com/ --- Jerome Brunet (13): ALSA: pcm: add more sample rate definitions ALSA: cmipci: drop SNDRV_PCM_RATE_KNOT ALSA: emu10k1: drop SNDRV_PCM_RATE_KNOT ALSA: hdsp: drop SNDRV_PCM_RATE_KNOT ALSA: hdspm: drop SNDRV_PCM_RATE_KNOT ASoC: cs35l36: drop SNDRV_PCM_RATE_KNOT ASoC: cs35l41: drop SNDRV_PCM_RATE_KNOT ASoC: cs53l30: drop SNDRV_PCM_RATE_KNOT ASoC: Intel: avs: drop SNDRV_PCM_RATE_KNOT ASoC: qcom: q6asm-dai: drop SNDRV_PCM_RATE_KNOT ASoC: sunxi: sun4i-codec: drop SNDRV_PCM_RATE_KNOT ASoC: cs35l34: drop useless rate contraint ASoC: spdif: extend supported rates to 768kHz include/sound/pcm.h | 31 +++++++++++++++++-------------- sound/core/pcm_native.c | 6 +++--- sound/pci/cmipci.c | 32 +++++++++----------------------- sound/pci/emu10k1/emupcm.c | 31 +++++-------------------------- sound/pci/rme9652/hdsp.c | 18 ++++++------------ sound/pci/rme9652/hdspm.c | 16 +--------------- sound/soc/codecs/cs35l34.c | 21 --------------------- sound/soc/codecs/cs35l36.c | 34 ++++++++++++---------------------- sound/soc/codecs/cs35l41.c | 34 +++++++++++----------------------- sound/soc/codecs/cs53l30.c | 24 +++--------------------- sound/soc/codecs/spdif_receiver.c | 3 ++- sound/soc/codecs/spdif_transmitter.c | 3 ++- sound/soc/intel/avs/pcm.c | 22 ++++++---------------- sound/soc/qcom/qdsp6/q6asm-dai.c | 31 ++++++++++--------------------- sound/soc/sunxi/sun4i-codec.c | 28 +++++++++------------------- 15 files changed, 96 insertions(+), 238 deletions(-) --- base-commit: 785f4052380684dbcc156203c537c799e2f4be09 change-id: 20240905-alsa-12-24-128-8edab4c08dd4 Best regards, -- Jerome
