[PATCH] ASoC: snd-soc-dummy: add Device Tree support
by Judy Hsiao 23 Jun '21

23 Jun '21

Support for loading the snd-soc-dummy via DeviceTree. This is useful to create dummy codec devices where we need to have some DAI links without a real Codec.

[PATCH v2 00/12] drm/vc4: hdmi: Enable Channel Mapping, IEC958, HBR Passthrough using hdmi-codec
by Maxime Ripard 23 Jun '21

23 Jun '21

Hi, hdmi-codec allows to have a lot of HDMI-audio related infrastructure in place, it's missing a few controls to be able to provide HBR passthrough. This series adds more infrastructure for the drivers, and leverages it in the vc4 HDMI controller driver. Thanks! Maxime Changes from v1: - Added an extra patch to clarify the iec958 controls iface policy - Added kerneldoc for the new iec958 PCM functions - s/EXPORT_SYMBOL/EXPORT_SYMBOL_GPL - Used the ALSA prefix where relevant - Rebased on drm-misc-next-2021-05-17 Dom Cobley (5): drm/vc4: hdmi: Set HD_CTL_WHOLSMP and HD_CTL_CHALIGN_SET drm/vc4: hdmi: Set HDMI_MAI_FMT drm/vc4: hdmi: Set VC4_HDMI_MAI_CONFIG_FORMAT_REVERSE drm/vc4: hdmi: Remove firmware logic for MAI threshold setting ARM: dts: bcm2711: Tune DMA parameters for HDMI audio Maxime Ripard (7): ALSA: doc: Clarify IEC958 controls iface ALSA: iec958: Split status creation and fill ASoC: hdmi-codec: Rework to support more controls ASoC: hdmi-codec: Add iec958 controls ASoC: hdmi-codec: Add a prepare hook drm/vc4: hdmi: Register HDMI codec drm/vc4: hdmi: Remove redundant variables .../kernel-api/writing-an-alsa-driver.rst | 13 +- arch/arm/boot/dts/bcm2711.dtsi | 4 +- drivers/gpu/drm/vc4/Kconfig | 1 + drivers/gpu/drm/vc4/vc4_hdmi.c | 322 ++++++++---------- drivers/gpu/drm/vc4/vc4_hdmi.h | 5 +- drivers/gpu/drm/vc4/vc4_regs.h | 30 ++ include/sound/hdmi-codec.h | 12 +- include/sound/pcm_iec958.h | 8 + sound/core/pcm_iec958.c | 176 +++++++--- sound/soc/codecs/hdmi-codec.c | 219 +++++++++--- 10 files changed, 508 insertions(+), 282 deletions(-) -- 2.31.1

Lenovo Legion/Yoga Slim 7 speaker output
by Cameron Berkenpas 23 Jun '21

23 Jun '21

Hello, I'm working on a patch to get audio output working on the speakers of the Lenovo Legion/Yoga Slim 7 laptops: https://bugzilla.kernel.org/attachment.cgi?id=297559&action=diff Please let me know if this isn't the right place for these types of questions. Both of these laptops have ALC287's that both seem to need some codec initialization to get the speakers working. For both laptops, the specs report ALC3306, but Linux on both systems reports that it's an ALC287, and looking at the PCI ID's on Windows agrees that it's an ALC287. This is my first time working on such a patch, and I'm having a headphone related problem: 1. When plugging headphones into the audio jack, I get sound on the headphones as expected. I see that the speakers are muted and the headphones are unmuted as expected in alsamixer. 2. When I unplug the headphones, I can no longer get speaker output. Monitoring alsamixer, I observe that unplugging the headphones results in the speakers being unmuted and the headphones are muted as expected. However, I am unable to get speaker output in this case. 3. If I plug in the headphones, don't play any sound, and then unplug the headphones, I see the same behavior in alsamixer, BUT speaker output still works. 4. If I apply the initialization verbs via hda-verb (the same verbs that I'm using in my patch), speaker output works again. 5. If speaker output is no longer working (due to #2), putting the laptop to sleep and resuming fixes the speakers. The code in the kernel seems to call the sound card's init again so this makes sense. In short, it seems I need to re-initialize the speakers when the headphones are unplugged. Studying sound/pci/hda/patch_realtek.c, there's alc_headset_mode_unplugged(), but as there's currently no case for 0x10ec0287 at all. I'm not sure adding in a case that re-initializes makes sense if the vast majority of ALC287's don't need to when headphones are unplugged. It seems none of the other cards, at least as far as I can tell, do a re-init when headphones are unplugged either. They just seem to setup some pins and coefficients for the most part if anything at all. How can I re-init the speakers when headphones are unplugged specifically for these specific models? The initial-initialization is only done for these laptops, I'm just unclear what, if any, mechanism there is for initialization on headphone unplugs? Thanks! -Cameron
