I wonder who is supposed to apply this patch. Either it should be split by file and go in via the respective maintainers, or it goes in via Greg's tree? I added Greg to To: for him to chime in.

[PATCH][next] ASoC: uapi: Replace zero-length arrays with __DECLARE_FLEX_ARRAY() helper
by Gustavo A. R. Silva 03 Feb '23

03 Feb '23

Zero-length arrays are deprecated and we are moving towards adopting C99 flexible-array members, instead. So, replace zero-length arrays declarations in anonymous union with the new __DECLARE_FLEX_ARRAY() helper macro. This helper allows for flexible-array members in unions.

[PATCH] Sound: pci/hda: Add quirk for HP Envy x360 ey0xxx
by Fae 02 Feb '23

02 Feb '23

This patch fixes speaker output on the HP Envy x360 ey0xxx The mic/speaker mute LEDs are still non-functional but they aren't required for basic funtionality Also the quirk is labeled ALC287_FIXUP_CS35L41_I2C_2 however it does not only apply to ALC287 Its function is the generic cs35l41 fixup telling the driver that there's 2 i2c speakers. It isn't actually specific to ALC287 I did have a bit of luck getting the mic mute LED to work but it was to finicky to submit ( I used the ALC245_FIXUP_HP_GPIO_LED quirk ) I had no luck getting the speaker mute LED to work Signed-off-by: Fae <faenkhauser(a)gmail.com> --- sound/pci/hda/cs35l41_hda.c | 3 ++- sound/pci/hda/patch_realtek.c | 1 + 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/sound/pci/hda/cs35l41_hda.c b/sound/pci/hda/cs35l41_hda.c index 129bffb431c22..21d8c2de128ff 100644 --- a/sound/pci/hda/cs35l41_hda.c +++ b/sound/pci/hda/cs35l41_hda.c @@ -1156,7 +1156,8 @@ static int cs35l41_no_acpi_dsd(struct cs35l41_hda *cs35l41, struct device *physd hw_cfg->valid = true; put_device(physdev); - if (strncmp(hid, "CLSA0100", 8) == 0) { + if ((strncmp(hid, "CLSA0100", 8) == 0) || + (strncmp(hid, "CSC3551", 7) == 0)) { hw_cfg->bst_type = CS35L41_EXT_BOOST_NO_VSPK_SWITCH; } else if (strncmp(hid, "CLSA0101", 8) == 0) { hw_cfg->bst_type = CS35L41_EXT_BOOST; diff --git a/sound/pci/hda/patch_realtek.c b/sound/pci/hda/patch_realtek.c index 8a57636f622e9..e7053cbc6bb6e 100644 --- a/sound/pci/hda/patch_realtek.c +++ b/sound/pci/hda/patch_realtek.c @@ -9179,6 +9179,7 @@ static const struct snd_pci_quirk alc269_fixup_tbl[] = { SND_PCI_QUIRK(0x103c, 0x83b9, "HP Spectre x360", ALC269_FIXUP_HP_MUTE_LED_MIC3), SND_PCI_QUIRK(0x103c, 0x841c, "HP Pavilion 15-CK0xx", ALC269_FIXUP_HP_MUTE_LED_MIC3), SND_PCI_QUIRK(0x103c, 0x8497, "HP Envy x360", ALC269_FIXUP_HP_MUTE_LED_MIC3), + SND_PCI_QUIRK(0x103c, 0x8a31, "HP ENVY x360 2-in-1 Laptop 15-ey0xxx", ALC287_FIXUP_CS35L41_I2C_2), SND_PCI_QUIRK(0x103c, 0x84da, "HP OMEN dc0019-ur", ALC295_FIXUP_HP_OMEN), SND_PCI_QUIRK(0x103c, 0x84e7, "HP Pavilion 15", ALC269_FIXUP_HP_MUTE_LED_MIC3), SND_PCI_QUIRK(0x103c, 0x8519, "HP Spectre x360 15-df0xxx", ALC285_FIXUP_HP_SPECTRE_X360), -- 2.37.1

[PATCH] ALSA: hda/hdmi: Use only dynamic PCM device allocation
by Jaroslav Kysela 27 Jan '23

27 Jan '23

Per discussion on the alsa-devel mailing list [1], the legacy PIN to PCM device mapping is obsolete nowadays. The maximum number of the simultaneously usable PCM devices is equal to the HDMI codec converters. Remove the extra PCM devices (beyond the detected converters) and force the use of the dynamic PCM device allocation. The legacy code is removed. I believe that all HDMI codecs have the jack sensing feature. Move the check to the codec probe function and print a warning, if a codec without this feature is detected.

[PATCH 0/9] ALSA: hda: Codec-reload bug fixes and cleanups
by Cezary Rojewski 17 Jan '23

17 Jan '23

Total of 6 fixes and 3 cleanups - cleanups are last. All of the fixes address problems that present themselves in situation when user engages in codec driver reload. Second condition to reproduce is two-step initialization of HDAudio codec - this is the case only for ASoC HDAudio bus driver as snd_hda_intel calls only compound function snd_hda_codec_new(). Once these conditions are met, several reload/unload scenarios end with null-ptr-deref and page faults. Goal of the series is to allow codec/bus driver reloading without any errors.

[PATCH 0/6] ASoC: samsung: fsd: audio support for FSD SoC
by Padmanabhan Rajanbabu 03 Jan '23

03 Jan '23

The intention of this patch series is to enable audio support on FSD SoC. The following features are added in samsung I2S interface: 1. Add TDM support on samsung I2S interface 2. Allow sound card to directly configure prescaler divider instead of calculating it from frame clock Also the sound card support for FSD SoC is added, which utilizes samsung I2S interface as CPU DAI. This patch is dependent on fsd-pinctrl fixes patch series [1] [1]: https://lkml.org/lkml/2022/10/13/257 Padmanabhan Rajanbabu (6): ASoC: samsung: i2s: TDM Support for CPU DAI driver ASoC: samsung: i2s: configure PSR from sound card dt-bindings: sound: Add sound card bindings for Tesla FSD ASoC: samsung: fsd: Add FSD soundcard driver arm64: dts: fsd: Add I2S DAI node for Tesla FSD arm64: dts: fsd: Add sound card node for Tesla FSD .../bindings/sound/tesla,fsd-card.yaml | 158 ++++++++ arch/arm64/boot/dts/tesla/fsd-evb.dts | 57 +++ arch/arm64/boot/dts/tesla/fsd-pinctrl.dtsi | 14 + arch/arm64/boot/dts/tesla/fsd.dtsi | 41 ++ sound/soc/samsung/Kconfig | 12 + sound/soc/samsung/Makefile | 2 + sound/soc/samsung/fsd-card.c | 349 ++++++++++++++++++ sound/soc/samsung/i2s-regs.h | 17 + sound/soc/samsung/i2s.c | 120 +++++- sound/soc/samsung/i2s.h | 1 + 10 files changed, 766 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/tesla,fsd-card.yaml create mode 100644 sound/soc/samsung/fsd-card.c -- 2.17.1

Regression playing 24bit/96kHz audio on USB audio interface between 5.10.94 and 5.15.21
by Ruud van Asseldonk 02 Jan '23

02 Jan '23

Hi, I have a program that configures a Behringer UMC404HD 192k USB audio interface for playback as follows (pseudocode): snd_pcm_hw_params_set_channels(pcm, hwp, 2); snd_pcm_hw_params_set_format(pcm, hwp, SND_PCM_FORMAT_S24_3LE); snd_pcm_hw_params_set_access(pcm, hwp, SND_PCM_ACCESS_MMAP_INTERLEAVED); snd_pcm_hw_params_set_rate(pcm, hwp, val=96000, dir=0); snd_pcm_hw_params_set_period_size_near(pcm, hwp, val=513, dir=0); // If I confirm at this point with snd_pcm_hw_params_get_period_size, // I get back 513. snd_pcm_hw_params_set_buffer_size_near(pcm, hwp, val=2052); snd_pcm_hw_params(pcm, hwp); // If I confirm with snd_pcm_hw_params_get_buffer_size, // I get back 2052. On Linux 5.10.94 (specifically Arch Linux ARM package linux-rpi-5.10.94-1), this succeeds, and I can play back audio just fine. On 5.15.21 (specifically linux-rpi-5.15.21-3), all the calls succeed apart from the last one, which returns EINVAL. (My actual program is written in Rust and uses a Rust wrapper library for libasound, https://docs.rs/alsa/0.6.0/alsa/, but the calls should be the ones listed.) I confirmed with snd_pcm_hw_params_test_format that the S24_3LE format is supported. On both kernels it is successful. I confirmed with snd_pcm_hw_params_test_rate that 96 kHz is supported. On both kernels it is successful. There are differences though. When I query these: snd_pcm_hw_params_get_period_size_min snd_pcm_hw_params_get_period_size_max snd_pcm_hw_params_get_buffer_size_min snd_pcm_hw_params_get_buffer_size_max Then on 5.10.94 (the good version), I get: period size min/max: 12/32768, buffer size min/max: 24/65536 But on 5.15.21 (the bad version), I get: period size min/max: 13/71332, buffer size min/max: 26/142663 Also, after I set the period size to 513, if I then query the buffer size min/max, on 5.10.94 I get: buffer size min/max: 1026/65536 But on 5.15.21 I get: buffer size min/max: 1027/142663 In lsmod, snd_usb_audio shows up, and from lsusb -v, the UMC404HD appears to be a standard USB audio interface. The lsusb output is identical on both kernels. Please let me know if there is anything I can do to help further diagnose the issue, or if I should report this elsewhere. Kind regards, Ruud van Asseldonk
