[PATCH 0/2] ASoC: Improve coverage in default KUnit runs
by Mark Brown 19 Jul '23

19 Jul '23

We have some KUnit tests for ASoC but they're not being run as much as they should be since ASoC isn't enabled in the configs used by default with KUnit and in the case of the topolofy tests there is no way to enable them without enabling drivers that use them. Let's improve that.

Fwd: Odd issue with ALSA connecting directly to HDMI audio output
by Ico Bukvic 19 Jul '23

19 Jul '23

Hi all, I have a consumer-level setup audio question. My research project uses a Raspberry Pi in conjunction with a small portable monitor that has built-in loudspeakers that are to be used via HDMI connection. The goal here is portability and minimal cost. Curiously, when trying to connect to monitor's loudspeakers (via HDMI) using ALSA, no matter what settings I pick, at worst I cannot get audio out, and at best, get a buzzy sound whose waveform is in the attached image. The sound is clearly periodic and impulse-like. It happens every 59 samples. Changing sample rate increases pitch, suggesting 59 samples remain constant regardless of the sampling rate. When playing the actual audio, you can hear it in the background, but this buzz is easily overpowering it. Changing sample rate or bit depth, or buffering, makes no difference. Selecting 8 channels for output (one of HDMI's standards, as far as I can tell), sometimes manages to output a tiny chunk of a good audio sample, and then goes silent. Now, even more curiously, when using the portaudio backend and connecting to the default pulseaudio sink, works just fine. What could be causing this discrepancy? Best, Ico -- Ivica Ico Bukvic, D.M.A. Director, Creativity + Innovation Director, Human-Centered Design iPhD Institute for Creativity, Arts, and Technology Virginia Tech Creative Technologies in Music School of Performing Arts – 0141 Blacksburg, VA 24061 (540) 231-6139 ico(a)vt.edu ci.icat.vt.edu l2ork.icat.vt.edu ico.bukvic.net

[PATCH 0/6] Add audio support in v4l2 framework
by Shengjiu Wang 19 Jul '23

19 Jul '23

Audio signal processing has the requirement for memory to memory similar as Video. This patch is to add this support in v4l2 framework, defined new buffer type V4L2_BUF_TYPE_AUDIO_CAPTURE and V4L2_BUF_TYPE_AUDIO_OUTPUT, defined new format v4l2_audio_format for audio case usage. The created audio device is named "/dev/audioX". And add memory to memory support for two kinds of i.MX ASRC module Shengjiu Wang (6): media: v4l2: Add audio capture and output support ASoC: fsl_asrc: define functions for memory to memory usage ASoC: fsl_easrc: define functions for memory to memory usage ASoC: fsl_asrc: Add memory to memory driver ASoC: fsl_asrc: enable memory to memory function ASoC: fsl_easrc: enable memory to memory function .../media/common/videobuf2/videobuf2-v4l2.c | 4 + drivers/media/v4l2-core/v4l2-dev.c | 17 + drivers/media/v4l2-core/v4l2-ioctl.c | 52 ++ include/media/v4l2-dev.h | 2 + include/media/v4l2-ioctl.h | 34 + include/uapi/linux/videodev2.h | 19 + sound/soc/fsl/Kconfig | 13 + sound/soc/fsl/Makefile | 2 + sound/soc/fsl/fsl_asrc.c | 175 +++- sound/soc/fsl/fsl_asrc.h | 2 + sound/soc/fsl/fsl_asrc_common.h | 54 ++ sound/soc/fsl/fsl_asrc_m2m.c | 878 ++++++++++++++++++ sound/soc/fsl/fsl_asrc_m2m.h | 48 + sound/soc/fsl/fsl_easrc.c | 255 ++++- sound/soc/fsl/fsl_easrc.h | 6 + 15 files changed, 1557 insertions(+), 4 deletions(-) create mode 100644 sound/soc/fsl/fsl_asrc_m2m.c create mode 100644 sound/soc/fsl/fsl_asrc_m2m.h -- 2.34.1

You mean "values" as the PCM positions? That is, when running in full-duplex mode, only the capture stream shows strange PCM positions, while PCM playback shows correctly? Or are both screwed up? And, how strange they are? They jump up/down, random values, or any patterns? thanks, Takashi > > Carl Klemm > > On Wed, 2023-07-19 at 09:27 +0200, Takashi Iwai wrote: > > On Wed, 19 Jul 2023 09:10:12 +0200, > > Carl Klemm wrote: > > > > > > Hi, > > > > > > see https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/3352 > > > htimestamp returns nonesensical values when recording is active on > > > a > > > EMU20k device > > > > The driver doesn't provide any own implementation of PCM tstamp, > > hence > > it must be the standard values.
