[PATCH 0/3] ALSA: usb-audio: Fix a few implicit fb sync issues
by Takashi Iwai 03 Jan '23

03 Jan '23

Hi, this is a series of patches for addressing the remaining problem with the implicit fb sync. The first one is to cover the left over EP run state at re-configuring PCM. The second one is a workaround for a regression with the hw constraints, and the last one is the refactoring and fix for the multiple EPs assigned in the format list.

[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

[PATCH v4 0/7] kselftest/alsa: pcm-test improvements
by Mark Brown 02 Jan '23

02 Jan '23

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration, support for providing user visible descriptions and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards. v4: - Rebase onto v6.2-rc1. v3: - "Rebase" onto Takashi's current tree (with a revert). - Include Jaroslav's changes to specify all tests in the configuration file parsing. - Add a new "description" field to the configuration instead of trying to name the tests. - Always run both default and per-system tests, logging our success at setting the per-system configurations as a separate test since they shouldn't fail. v2: - Rebase onto Takashi's current tree. - Tweak the buffer sizes for the newly added cases, don't be quite so ambitious in how big a buffer we request for 96kHz and don't go quite so small for 8kHz since some devices start hitting lower limits on period size and struggle to deliver accurate timing.

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

[PATCH] ASoC: qcom: lpass-cpu: Fix fallback SD line index handling
by Brian Norris 02 Jan '23

02 Jan '23

These indices should reference the ID placed within the dai_driver array, not the indices of the array itself. This fixes commit 4ff028f6c108 ("ASoC: qcom: lpass-cpu: Make I2S SD lines configurable"), which among others, broke IPQ8064 audio (sound/soc/qcom/lpass-ipq806x.c) because it uses ID 4 but we'd stop initializing the mi2s_playback_sd_mode and mi2s_capture_sd_mode arrays at ID 0.

Front Audio (Headphone) and Optical Not Working in Rocky Linux 9
by yakajirri - a001 01 Jan '23

01 Jan '23

With Rocky Linux 9 (clone of RHEL 9), I do not get audio of the front headphone jack or the optical output on the back. I do get audio out of the line out on the back. The front port does not work with Rocky Linux 8, Ubuntu and Fedora, and I did not test the optical. With Windows, the front jack works as expected with the realtek driver installed, and I did not test the optical on Windows. The output of /usr/sbin/alsa-info.sh is here: http://alsa-project.org/db/?f=0d71a1351cd49f220c36fe69cc9af93f1d71ee3c I built the computer with a Gigabyte Z690 AERO G motherboard that has a realtek alc4080 codec and Intel Z690 chipset. With Rocky Linux 9, without the headphones plugged in the sounds settings show: digital output (s/sdif) - usb hdmi/displayport-built-in audio when plug in headphones in the front jack “headphones - usb audio” appears and disappears when I unplug the headphones. If I use the following command, I can hear the audio clip through the headphones: aplay -D plughw:Audio,1 /usr/share/sounds/alsa/Front_Left.wav If I use the following command, I can hear the audio clip through the optical: aplay -D plughw:Audio,2 /usr/share/sounds/alsa/Front_Left.wav I’m using alsa-lib 1.2.7 from the Rocky Linux repo. I tried to compile 1.2.8 from source but when I run “./configure” I got the error: ./configure: line 2998: syntax error near unexpected token `external' ./configure: line 2998: `AM_GNU_GETTEXT(external)' I noticed https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/USB-Audio/US… has more If.realtek-alc4080 entries. When I copied the If.realtek-alc4080 section into /usr/share/alsa/ucm2/USB-Audio/USB-Audio.conf and /usr/share/alsa/ucm2/conf.d/USB-Audio/USB-Audio.conf, and after I rebooted, I get the same performance. One thing I noticed in https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/USB-Audio/US… is the only Gigabyte entry under If.realtek-alc4080 is “Gigabyte Z590 Aorus Pro AX”. I see other manufactures have Intel Z690 chipset support but not Gigabyte. I’m not sure if I’m hitting a bug or if my motherboard is not supported. Please point me in the correct direction if this isn’t an AlSA issue. I posted the Rocky Linux forum but was not able to resolve the issue. Brian

[PATCH AUTOSEL 4.19] ASoC: Intel: bytcr_rt5640: Add quirk for the Advantech MICA-071 tablet
by Sasha Levin 31 Dec '22

31 Dec '22

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit a1dec9d70b6ad97087b60b81d2492134a84208c6 ] The Advantech MICA-071 tablet deviates from the defaults for a non CR Bay Trail based tablet in several ways: 1. It uses an analog MIC on IN3 rather then using DMIC1 2. It only has 1 speaker 3. It needs the OVCD current threshold to be set to 1500uA instead of the default 2000uA to reliable differentiate between headphones vs headsets Add a quirk with these settings for this tablet.
