[PATCH] ASoC: da7219: Fix pole orientation detection on OMTP headsets when playing music
by David Rau 09 Feb '23

09 Feb '23

The OMTP pin define headsets can be mis-detected as line out instead of OMTP, causing obvious issues with audio quality. This patch is to put increased resistances within the device at a suitable point. To solve this issue better, the new mechanism setup ground switches with conditional delay control and these allow for more stabile detection process to operate as intended. This conditional delay control will not impact the hardware process but use extra system resource. This commit improves control of ground switches in the AAD logic.

[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 v1] ASoC: qcom: lpass-platform: Use SNDRV_DMA_TYPE_NONCOHERENT page allocation
by Judy Hsiao 26 Jan '23

26 Jan '23

Replace SNDRV_DMA_TYPE_DEV by SNDRV_DMA_TYPE_NONCOHERENT for pcm buffer allocation. We measured about 18x performance improvement when accessing the snd_pcm_mmap() buffer from userspace. Eg: aarch64 with internal speaker == SNDRV_DMA_TYPE_DEV frames_per_second=66.4557M/s max_time_per_4096_frames=106.094u time_per_4096_frames=61.6351us SNDRV_DMA_TYPE_NONCOHERENT frames_per_second=1028.58M/s max_time_per_4096_frames=20.312u time_per_4096_frames=3.98221us Signed-off-by: Judy Hsiao <judyhsiao(a)chromium.org> --- sound/soc/qcom/lpass-platform.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sound/soc/qcom/lpass-platform.c b/sound/soc/qcom/lpass-platform.c index b41ab7a321ae..ef5cb40b2d9b 100644 --- a/sound/soc/qcom/lpass-platform.c +++ b/sound/soc/qcom/lpass-platform.c @@ -1181,7 +1181,7 @@ static int lpass_platform_pcm_new(struct snd_soc_component *component, if (is_cdc_dma_port(dai_id)) return lpass_platform_prealloc_cdc_dma_buffer(component, pcm, dai_id); - return snd_pcm_set_fixed_buffer_all(pcm, SNDRV_DMA_TYPE_DEV, + return snd_pcm_set_fixed_buffer_all(pcm, SNDRV_DMA_TYPE_NONCOHERENT, component->dev, size); } -- 2.39.0.rc0.267.gcb52ba06e7-goog

Hm, is it specific to Xen, i.e. if you run the normal kernel on the same machine, does it still work? In anyway, please check the behavior with 6.1-rc8 + the commit cc26516374065a34e10c9a8bf3e940e42cd96e2a ALSA: memalloc: Allocate more contiguous pages for fallback case from for-next of my sound git tree (which will be in 6.2-rc1).

[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. Amadeusz Sławiński (2): ALSA: hda: Reset all SIE bits in INTCTL ALSA: hda: Remove unused macro definition Cezary Rojewski (7): ALSA: hda: Do not unset preset when cleaning up codec ALSA: hda: Fix null-ptr-deref when i915 fails and hdmi is denylisted ALSA: hda: Make device usage_count consistent across subsequent probing ALSA: hda: Fix put_device() inconsistency in error path ALSA: hda: Skip event processing for unregistered codecs ALSA: hda: Fix page fault in snd_hda_codec_shutdown() ALSA: hda/realtek: Remove redundant init_hook() in alc_default_init() include/sound/hda_codec.h | 1 - include/sound/hdaudio.h | 1 + sound/hda/ext/hdac_ext_controller.c | 7 --- sound/hda/hdac_bus.c | 2 +- sound/hda/hdac_controller.c | 7 +-- sound/pci/hda/hda_bind.c | 7 +++ sound/pci/hda/hda_codec.c | 83 +++++++++++++++-------------- sound/pci/hda/patch_realtek.c | 3 -- sound/soc/codecs/hda.c | 4 +- 9 files changed, 56 insertions(+), 59 deletions(-) -- 2.25.1
