Is there any way to install alsa-lib with the suid bit set?
by Stefan Alexe 03 Feb '23

03 Feb '23

I am trying to only use a static /dev. I have opened an issue about this on GitHub and got it to work only as the root user. This resembles my experience with xorg. In that case I had to use the suid use flag. Is there an equivalent in this situation?

[PATCH v3 0/6] Fix default DMIC gain on AMD PDM drivers
by Mario Limonciello 02 Feb '23

02 Feb '23

It's been reported that a number of laptops have a low volume level from the digital microphone compared to Windows. AMD offers a register that can adjust the gain for PDM which is not configured at maximum gain by default. To fix this change the default for all 3 drivers to raise the gain but also offer a module parameter. The module parameter can be used for debugging if the gain is too high on a given laptop. This is intentionally split into multiple patches for default and parameter so that if the default really does behave better universally we can bring it back to stable too later. v2->v3: * Use clamp and clear properly Mario Limonciello (6): ASoC: amd: yc: Adjust the gain for PDM DMIC ASoC: amd: yc: Add a module parameter to influence pdm_gain ASoC: amd: renoir: Adjust the gain for PDM DMIC ASoC: amd: renoir: Add a module parameter to influence pdm_gain ASoC: amd: ps: Adjust the gain for PDM DMIC ASoC: amd: ps: Add a module parameter to influence pdm_gain sound/soc/amd/ps/acp63.h | 2 +- sound/soc/amd/ps/ps-pdm-dma.c | 8 +++++++- sound/soc/amd/renoir/acp3x-pdm-dma.c | 8 +++++++- sound/soc/amd/renoir/rn_acp3x.h | 2 +- sound/soc/amd/yc/acp6x-pdm-dma.c | 8 +++++++- sound/soc/amd/yc/acp6x.h | 2 +- 6 files changed, 24 insertions(+), 6 deletions(-) -- 2.34.1

[PATCH] ALSA: hda: Fix the control element identification for multiple codecs
by Jaroslav Kysela 02 Feb '23

02 Feb '23

Some motherboards have multiple HDA codecs connected to the serial bus. The current code may create multiple mixer controls with the almost identical identification. The current code use id.device field from the control element structure to store the codec address to avoid such clashes for multiple codecs. Unfortunately, the user space do not handle this correctly. For mixer controls, only name and index are used for the identifiers. This patch fixes this problem to compose the index using the codec address as an offset in case, when the control already exists. It is really unlikely that one codec will create 10 similar controls. This patch adds new kernel module parameter 'ctl_dev_id' to allow select the old behaviour, too. The CONFIG_SND_HDA_CTL_DEV_ID Kconfig option sets the default value.

[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

Thanks very much for the bisection (complete log at [1])! The bisection claims the first bad commit is: 833477fce7a1 ("Merge tag 'sound-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound") with parents: 7e6739b9336e ("Merge tag 'drm-next-2022-10-05' of git://anongit.freedesktop.org/drm/drm") 86a4d29e7554 ("Merge tag 'asoc-v6.1' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus") Both 7e6739b9336e and 86a4d29e7554 tested "good" during the bisection. There is a minor conflict when merging 86a4d29e7554 into the upstream, but I can't imagine that being resolved incorrectly. Would you mind turning off CONFIG_SOUND in your .config and testing 833477fce7a1 again? I'm a little skeptical that the hang would be sound-related, but I guess it's a place to start.

[PATCH v2] ALSA: pci: lx6464es: fix a debug loop
by Dan Carpenter 01 Feb '23

01 Feb '23

This loop accidentally reuses the "i" iterator for both the inside and the outside loop. The value of MAX_STREAM_BUFFER is 5. I believe that chip->rmh.stat_len is in the 2-12 range. If the value of .stat_len is 4 or more then it will loop exactly one time, but if it's less then it is a forever loop. It looks like it was supposed to combined into one loop where conditions are checked.
