[PATCH] ASoC: fsl_xcvr: Enable 2 * TX bit clock for spdif only case
by Shengjiu Wang 22 Nov '23

22 Nov '23

The bit 10 in TX_DPTH_CTRL register controls the TX clock rate. If this bit is set, TX datapath clock should be = 2* TX bit rate. If this bit is not set, TX datapath clock should be 10* TX bit rate. As the spdif only case, we always use 2 * TX bit clock, so this bit need to be set.

[PATCH v4] ASoC: cs43130: Allow driver to work without IRQ connection
by Maciej Strozek 22 Nov '23

22 Nov '23

Add a polling mechanism that will keep the driver operational even in absence of physical IRQ connection. If IRQ line is detected, the driver will continue working as usual, in case of missing IRQ line it will fallback to the polling mechanism introduced in this change. This will support users which choose not to connect an IRQ line as it is not critical to part's operation.

[PATCH] ALSA: hda: cs35l56: Enable low-power hibernation mode on SPI
by Richard Fitzgerald 22 Nov '23

22 Nov '23

SPI hibernation is now supported with the latest hibernation/wake sequences in the shared ASoC code. This has a functional dependency on two commits: commit 3df761bdbc8b ("ASoC: cs35l56: Wake transactions need to be issued twice") commit a47cf4dac7dc ("ASoC: cs35l56: Change hibernate sequence to use allow auto hibernate") To protect against this, enabling hibernation is conditional on CS35L56_WAKE_HOLD_TIME_US being defined, which indicates that the new hibernation sequences are available.

Bug report - kernel 6.6.1 and 6.6.2 - speakers problem on Lenovo Legion 7 ACHg6 (82N6) laptop
by Primož Šušterič 22 Nov '23

22 Nov '23

BUG REPORT: Summary: I am experiencing an issue with my Lenovo Legion 7 ACHg6 (82N6) laptop's audio on Linux kernel version 6.6.2-zen1-1-zen on EndeavourOS Linux, where the sound works perfectly through Bluetooth, HDMI, and other outputs but not through the laptop's built-in speakers. Steps to Reproduction Boot into Linux kernel version 6.6.2-zen1-1-zen, 6.6.1-zen, 6.6.1-arch and 6.6.2-arch. Test audio output through Bluetooth and HDMI, which works as expected. Attempt to play sound through laptop's built-in speakers (identified as 'HD-Audio Generic', device 0: ALC287 Analog in aplay -l output). Observe that no sound is produced from the laptop speakers, despite other audio outputs working correctly. Here are detailed information about the system and Bug: uname -a Linux robo008 6.6.2-zen1-1-zen #1 ZEN SMP PREEMPT_DYNAMIC Mon, 20 Nov 2023 23:17:26 +0000 x86_64 GNU/Linux ____________________________________________________________________________ lspci -v 00:00.0 Host bridge: Advanced Micro Devices, Inc.

[PATCH v5 1/2] ASoC: dt-bindings: sound-card-common: List sound widgets ignoring system suspend
by Chancel Liu 21 Nov '23

Fix incorrect usages of `strerror`
by GitHub pull_request - opened 21 Nov '23

21 Nov '23

alsa-project/alsa-utils pull request #245 was opened from i-Pear: `strerror` takes the `errno` directly as its argument, negating it will result in an "Unknown error". This fixes such usages across multiple modules. Request URL : https://github.com/alsa-project/alsa-utils/pull/245 Patch URL : https://github.com/alsa-project/alsa-utils/pull/245.patch Repository URL: https://github.com/alsa-project/alsa-utils

No sound over HDMI using USB Type-C port replicator with Philips TV
by Paul Menzel 21 Nov '23

21 Nov '23

Dear Linux folks, Connecting a USB Type-C port replicator [1] to the only USB Type-C port of the Dell XPS 13 9360 with Debian sid/unstable and Debian’s Linux kernel 6.10.5, and then connecting a Philips 40PFL5206H/12 TV device to the HDMI port, GNOME shows the HDMI sound device, but selecting it as output device, the TV does not play any sound. (Video display works.) Using the same USB Type-C port replicator with the Google Chromebook Lenovo IdeaPad Duet, video and sound over HDMI work. Using the same USB Type-C port replicator with the same Dell XPS 13 9360, but a Samsung TV, video and sound over HDMI also work. Please found the output of `/sbin/alsa-info` from *alsa-utils* 1.2.10-1 attached. Kind regards, Paul [1]: https://lmp-adapter.com/product/lmp-usb-c-mini-dock/?attribute_pa_color=sil… "LMP USB-C mini Dock (P/N 15954)"

[PATCH v10 00/14] Add audio support in v4l2 framework
by Shengjiu Wang 21 Nov '23

Audio signal processing also has the requirement for memory to memory similar as Video. This asrc memory to memory (memory ->asrc->memory) case is a non real time use case. User fills the input buffer to the asrc module, after conversion, then asrc sends back the output buffer to user. So it is not a traditional ALSA playback and capture case. It is a specific use case, there is no reference in current kernel. v4l2 memory to memory is the closed implementation, v4l2 current support video, image, radio, tuner, touch devices, so it is not complicated to add support for this specific audio case. Because we had implemented the "memory -> asrc ->i2s device-> codec" use case in ALSA. Now the "memory->asrc->memory" needs to reuse the code in asrc driver, so the first 3 patches is for refining the code to make it can be shared by the "memory->asrc->memory" driver. The main change is in the v4l2 side, A /dev/vl4-audioX will be created, user applications only use the ioctl of v4l2 framework. Other change is to add memory to memory support for two kinds of i.MX ASRC module. changes in v10 - remove FIXED_POINT type - change code base on media: v4l2-ctrls: add support for fraction_bits - fix issue reported by kernel test robot - remove module_alias changes in v9: - add MEDIA_ENT_F_PROC_AUDIO_RESAMPLER. - add MEDIA_INTF_T_V4L_AUDIO - add media controller support - refine the vim2m-audio to support 8k<->16k conversion. changes in v8: - refine V4L2_CAP_AUDIO_M2M to be 0x00000008 - update doc for FIXED_POINT - address comments for imx-asrc changes in v7: - add acked-by from Mark - separate commit for fixed point, m2m audio class, audio rate controls - use INTEGER_MENU for rate, FIXED_POINT for rate offset - remove used fmts - address other comments for Hans changes in v6: - use m2m_prepare/m2m_unprepare/m2m_start/m2m_stop to replace m2m_start_part_one/m2m_stop_part_one, m2m_start_part_two/m2m_stop_part_two. - change V4L2_CTRL_TYPE_ASRC_RATE to V4L2_CTRL_TYPE_FIXED_POINT - fix warning by kernel test rebot - remove some unused format V4L2_AUDIO_FMT_XX - Get SNDRV_PCM_FORMAT from V4L2_AUDIO_FMT in driver. - rename audm2m to viaudm2m. changes in v5: - remove V4L2_AUDIO_FMT_LPCM - define audio pixel format like V4L2_AUDIO_FMT_S8... - remove rate and format in struct v4l2_audio_format. - Add V4L2_CID_ASRC_SOURCE_RATE and V4L2_CID_ASRC_DEST_RATE controls - updata document accordingly. changes in v4: - update document style - separate V4L2_AUDIO_FMT_LPCM and V4L2_CAP_AUDIO_M2M in separate commit changes in v3: - Modify documents for adding audio m2m support - Add audio virtual m2m driver - Defined V4L2_AUDIO_FMT_LPCM format type for audio. - Defined V4L2_CAP_AUDIO_M2M capability type for audio m2m case. - with modification in v4l-utils, pass v4l2-compliance test. changes in v2: - decouple the implementation in v4l2 and ALSA - implement the memory to memory driver as a platfrom driver and move it to driver/media - move fsl_asrc_common.h to include/sound folder Shengjiu Wang (14): ASoC: fsl_asrc: define functions for memory to memory usage ASoC: fsl_easrc: define functions for memory to memory usage ASoC: fsl_asrc: move fsl_asrc_common.h to include/sound ASoC: fsl_asrc: register m2m platform device ASoC: fsl_easrc: register m2m platform device media: uapi: Add V4L2_CAP_AUDIO_M2M capability flag media: v4l2: Add audio capture and output support media: uapi: Define audio sample format fourcc type media: uapi: Add V4L2_CTRL_CLASS_M2M_AUDIO media: uapi: Add audio rate controls support media: uapi: Declare interface types for Audio media: uapi: Add an entity type for audio resampler media: imx-asrc: Add memory to memory driver media: vim2m-audio: add virtual driver for audio memory to memory .../media/mediactl/media-types.rst | 11 + .../userspace-api/media/v4l/buffer.rst | 6 + .../userspace-api/media/v4l/common.rst | 1 + .../media/v4l/dev-audio-mem2mem.rst | 71 + .../userspace-api/media/v4l/devices.rst | 1 + .../media/v4l/ext-ctrls-audio-m2m.rst | 41 + .../userspace-api/media/v4l/pixfmt-audio.rst | 87 ++ .../userspace-api/media/v4l/pixfmt.rst | 1 + .../media/v4l/vidioc-enum-fmt.rst | 2 + .../media/v4l/vidioc-g-ext-ctrls.rst | 4 + .../userspace-api/media/v4l/vidioc-g-fmt.rst | 4 + .../media/v4l/vidioc-querycap.rst | 3 + .../media/videodev2.h.rst.exceptions | 3 + .../media/common/videobuf2/videobuf2-v4l2.c | 4 + drivers/media/platform/nxp/Kconfig | 13 + drivers/media/platform/nxp/Makefile | 1 + drivers/media/platform/nxp/imx-asrc.c | 1264 +++++++++++++++++ drivers/media/test-drivers/Kconfig | 11 + drivers/media/test-drivers/Makefile | 1 + drivers/media/test-drivers/vim2m-audio.c | 799 +++++++++++ drivers/media/v4l2-core/v4l2-compat-ioctl32.c | 9 + drivers/media/v4l2-core/v4l2-ctrls-defs.c | 10 + drivers/media/v4l2-core/v4l2-dev.c | 21 + drivers/media/v4l2-core/v4l2-ioctl.c | 66 + drivers/media/v4l2-core/v4l2-mem2mem.c | 13 +- include/media/v4l2-dev.h | 2 + include/media/v4l2-ioctl.h | 34 + .../fsl => include/sound}/fsl_asrc_common.h | 60 + include/uapi/linux/media.h | 2 + include/uapi/linux/v4l2-controls.h | 9 + include/uapi/linux/videodev2.h | 41 + sound/soc/fsl/fsl_asrc.c | 144 ++ sound/soc/fsl/fsl_asrc.h | 4 +- sound/soc/fsl/fsl_asrc_dma.c | 2 +- sound/soc/fsl/fsl_easrc.c | 233 +++ sound/soc/fsl/fsl_easrc.h | 6 +- 36 files changed, 2977 insertions(+), 7 deletions(-) create mode 100644 Documentation/userspace-api/media/v4l/dev-audio-mem2mem.rst create mode 100644 Documentation/userspace-api/media/v4l/ext-ctrls-audio-m2m.rst create mode 100644 Documentation/userspace-api/media/v4l/pixfmt-audio.rst create mode 100644 drivers/media/platform/nxp/imx-asrc.c create mode 100644 drivers/media/test-drivers/vim2m-audio.c rename {sound/soc/fsl => include/sound}/fsl_asrc_common.h (60%) -- 2.34.1
