[alsa-devel] [PATCH] ALSA: hda/tegra: compatible string as shortname
by Sameer Pujar 29 Nov '18

29 Nov '18

By default HDA sound card is registered with shortname "tegra-hda". Same driver is used across tegra platforms and it is necessary to distinguish between platforms to use platform specific settings from userspace. One such example is, hdmi port on different platforms use different alsa pcm device ID. For hdmi playback to work it should open correct pcm device depending on the platform. This patch applies shortname from first compatible string provided in root node of device tree. Userspace then can use this card name to apply specific settings.

[alsa-devel] Subwoofers aren't working on ALC298 (Lenovo Yoga C930 Laptop)
by Jonathan Reeve 29 Nov '18

29 Nov '18

Hi Alsa Devs, I've been struggling with a sound issue for a while now. I just bought a new laptop that's known for its high-quality audio. It's billed as a Dolby Atmos speaker system, and it appears to be using a ALC298 card (or so I gathered from `aplay -l`). From what I can tell, it has tweeters in the back, and subwoofers on the bottom of the laptop. It sounds really great in Windows, but tinny and flat in Linux. I'm guessing this is because the subwoofers aren't being engaged. Here are some things I've tried so far: - Tweaking what is possible to tweak in GNOME. - Running pavucontrol. No useful options here. - Unmuting everything in alsamixer. Unmuting only some things in alsamixer. - Running hdajackretask, from the alsaTools package. It seems to correctly recognize that there are some unassigned pins, and even gives me the option of assigning them to "internal speaker (LFE)," which sounds like it could be a bass output. But when I click "apply now" or "apply boot options," the scripts fail by saying they can't find tools like md or tee. I can run the scripts it generates manually, but then the changes don't really seem to take effect. - Following the instructions from the ALSA page on the wiki, and trying all kinds of different options - All of the above, and also restarting alsa / snd_hda / pulseaudio all manually. As far as I can tell, I'm running the latest version of ALSA, since I'm on NixOS unstable, and [[https://github.com/NixOS/nixpkgs/blob/master/pkgs/os-specific/linux/alsa-fi… build script]] seems to grab the latest version. [[http://www.alsa-project.org/db/?f=8c072b3fbb139d350cd0e2c4c98cbb7736c6455a]…'s the output from my alsa-info.sh.]] I don't know enough about ALSA, or sound hardware, to know what's going on there. Is it obvious from my alsa-info which pins I should try reassigning to which channels? And does anyone know of a good way of doing this? Preferably one that doesn't use hdajackretask, which doesn't appear to work on NixOS. [[https://unix.stackexchange.com/questions/482885/how-can-i-get-my-laptops-in… also posted a few more details about this on this StackExchange question.]] I hope that getting this to work will not only help me, but others with this same laptop or speaker configuration. Thanks in advance for any help you'd be able to provide! Best, Jonathan

[alsa-devel] [RFC PATCH 0/6] ASoC:Intel:Skylake: Enable HDaudio legacy fallback
by Pierre-Louis Bossart 28 Nov '18

28 Nov '18

This patchset is provided as an RFC and should not be merged as is (Turkey break in the USA and more validation needed). This is however a good time to gather comments. This work is the result of multiple email discussions to finally provide more flexibility for distributions to chose whether to stick with the legacy HDaudio driver or to enable the SST/Skylake driver for newer platforms (required e.g. for digital microphone support) The patches add support for CoffeeLake, simplify the probe for the Skylake driver, introduce more compile-time granularity so that platforms can be selected individually and last provide a dynamic fallback mechanism when two drivers are registered for the same PCI ID. When the SOF driver is released, the same mechanism will be used to enable the SOF-legacy fallback. There will be no plans to enable an SOF->SST falback. Pierre-Louis Bossart (4): ASoC: Intel: Skylake: stop init/probe if DSP is not present ASoC: Intel: Skylake: remove useless tests on DSP presence ASoC: Intel: Skylake: Add more platform granularity ALSA: hda: add fallback capabilities for SKL+ platforms Takashi Iwai (2): ASoC: Intel: Skylake: Add CFL-S support ALSA: hda: Allow fallback binding with legacy HD-audio for Intel SKL+ include/sound/hdaudio.h | 6 + sound/pci/hda/Kconfig | 40 +++++++ sound/pci/hda/hda_controller.h | 2 +- sound/pci/hda/hda_intel.c | 51 ++++++-- sound/soc/intel/Kconfig | 86 ++++++++++++-- sound/soc/intel/boards/Kconfig | 16 ++- sound/soc/intel/skylake/skl-messages.c | 8 ++ sound/soc/intel/skylake/skl.c | 154 +++++++++++++++++++------ 8 files changed, 311 insertions(+), 52 deletions(-) -- 2.17.1

[alsa-devel] [PATCH] ASoC: rsnd: tidyup registering method for rsnd_kctrl_new()
by Kuninori Morimoto 28 Nov '18

28 Nov '18

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Current rsnd dvc.c is using flags to avoid duplicating register for MIXer case. OTOH, commit e894efef9ac7 ("ASoC: core: add support to card rebind") allows to rebind sound card without rebinding all drivers. Because of above patch and dvc.c flags, it can't re-register kctrl if only sound card was rebinded, because dvc is keeping old flags. (Of course it will be no problem if rsnd driver also be rebinded, but it is not purpose of above patch). This patch checks current card registered kctrl when registering. In MIXer case, it can avoid duplicate register if card already has same kctrl. In rebind case, it can re-register kctrl because card registered kctl had been removed when unbinding. This patch is updated version of commit b918f1bc7f1ce ("ASoC: rsnd: DVC kctrl sets once") Reported-by: Nguyen Viet Dung <dung.nguyen.aj(a)renesas.com> Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Tested-by: Nguyen Viet Dung <dung.nguyen.aj(a)renesas.com> Cc: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx(a)renesas.com> --- > Mark This patch is for v4.20-rcX sound/soc/sh/rcar/core.c | 12 ++++++++++++ sound/soc/sh/rcar/dvc.c | 8 -------- 2 files changed, 12 insertions(+), 8 deletions(-) diff --git a/sound/soc/sh/rcar/core.c b/sound/soc/sh/rcar/core.c index 56469ac..031cd5b 100644 --- a/sound/soc/sh/rcar/core.c +++ b/sound/soc/sh/rcar/core.c @@ -1476,6 +1476,18 @@ int rsnd_kctrl_new(struct rsnd_mod *mod, }; int ret; + /* + * 1) Avoid duplicate register (ex.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

[alsa-devel] [PATCH 0/2] ASoC: omap-mcpdm: Support for handling pdmclk

Hi, This series is on top of the pm_qos changes I have sent earlier today. I have sent this originally two years ago: https://patchwork.kernel.org/patch/9119551/ But needed to revert it as the MFD and clk changes were not merged in time: https://patchwork.kernel.org/patch/9287431/ The dts patches are already upstream, only the patch for McPDM is missing. I have separated the binding document update and the driver patch and also added the return value check for the clk_prepare_enable() as per Mark's comment.

[alsa-devel] [PATCH v5 0/2] Introduce dmic mode switch delay parameter
by Jenny TC 28 Nov '18

28 Nov '18

Some DMICs need clock to be running for a specified duration as per the DMIC spec to complete the mode transition like sleep to normal, off to normal etc. This series add a mode-switch delay which will prevent the clock from being turned off without complying with manufacturer timing specifications. Also introduces a module parameter for the wakeup_delay parameter. v1: First patch set v2: 1). Removed ACPI device entry since a) The DMIC vendor doesn't have an ACPI vendor ID b) The ACPI enumeration creates one more device and conflicts with the existing skl.c dmic platform device registration. 2). Updated commit message v3: Updated commit message and introduced module param for wakeup_delay v4: Addressed parameter name to align with existing parameter. Added dt entry in Documentation v5: Validate modeswitch_delay to ensure sensible value Jenny TC (2): ASoC: dmic: introduce mode switch delay ASoC: dmic: introduce module_param wakeup_delay Documentation/devicetree/bindings/sound/dmic.txt | 2 ++ sound/soc/codecs/dmic.c | 40 ++++++++++++++++++++++++ 2 files changed, 42 insertions(+) -- 1.9.1
