alsa-lib fails test with clang-16
by GitHub issues - opened 27 May '23

27 May '23

alsa-project/alsa-lib issue #323 was opened from fsvm88: Hello, While building is fine, testing alsa-lib on Gentoo fails since clang-16, due to clang-16 defaulting to c99. The problem is at `alsa-lib-1.2.8/test/oldapi.c`, in the typedef declaration, which leads to the following error: ``` alsa-lib-1.2.8/test/oldapi.c:40:6: error: incompatible function pointer types assigning to 'myfcn *' (aka 'void (*)(void *)') from 'int (*)(const snd_pcm_hw_params_t *)' (aka 'int (*)(const struct _snd_pcm_hw_params *)') [-Werror,-Wincompatible-func fcn = &snd_pcm_hw_params_get_access; ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``` [This is the Gentoo bug with all the information](https://bugs.gentoo.org/885551) [I have created a patch based on the compiler's suggestion](https://885551.bugs.gentoo.org/attachment.cgi?id=861055), but I'm not sure if it's the right way to solve this.

[PATCH 00/13] ALSA: hda: Adding support for CS35L56 on HDA systems
by Richard Fitzgerald 26 May '23

26 May '23

This set of patches adds support for using the CS35L56 boosted smart amplifier on HDA systems. In these systems the CS35L56 audio is routed through a HDA-to-I2S bridge codec. This doesn't include the changes to the Realtek driver to actually hook up the CS35L56 driver, because we don't yet have the QUIRK IDs to associate it with. But we want to publish the driver now so that it is available for bringing up hardware with the CS35L56. The first 10 patches are moving code out of the ASoC driver and into the shared library so that it can be shared with the HDA driver. Patch #11 fixes missing #includes in the HDA headers so that the CS35L56 driver doesn't have to #include headers that it doesn't use. Finally, #12 and #13 actually add the support for CS35L56 on HDA. Richard Fitzgerald (5): ASoC: cs35l56: Move runtime suspend/resume to shared library ASoC: cs35l56: Move cs_dsp init into shared library ASoC: cs35l56: Move part of cs35l56_init() to shared library ASoC: cs35l56: Pass correct pointer to cs35l56_irq() ALSA: hda: Fix missing header dependencies Simon Trimmer (8): ASoC: cs35l56: Move shared data into a common data structure ASoC: cs35l56: Make cs35l56_system_reset() code more generic ASoC: cs35l56: Convert utility functions to use common data structure ASoC: cs35l56: Move utility functions to shared file ASoC: cs35l56: Make common function for control port wait ASoC: cs35l56: Make a common function to shutdown the DSP ALSA: hda: Add mute_hook to hda_component ALSA: hda/cs35l56: Add driver for Cirrus Logic CS35L56 amplifier include/sound/cs35l56.h | 29 +- sound/pci/hda/Kconfig | 31 + sound/pci/hda/Makefile | 6 + sound/pci/hda/cs35l56_hda.c | 995 ++++++++++++++++++++++++++++++ sound/pci/hda/cs35l56_hda.h | 48 ++ sound/pci/hda/cs35l56_hda_i2c.c | 69 +++ sound/pci/hda/cs35l56_hda_spi.c | 68 ++ sound/pci/hda/hda_auto_parser.h | 2 + sound/pci/hda/hda_component.h | 1 + sound/pci/hda/hda_generic.h | 3 + sound/soc/codecs/cs35l56-i2c.c | 14 +- sound/soc/codecs/cs35l56-sdw.c | 72 +-- sound/soc/codecs/cs35l56-shared.c | 459 +++++++++++++- sound/soc/codecs/cs35l56-spi.c | 10 +- sound/soc/codecs/cs35l56.c | 648 ++++--------------- sound/soc/codecs/cs35l56.h | 15 +- 16 files changed, 1878 insertions(+), 592 deletions(-) create mode 100644 sound/pci/hda/cs35l56_hda.c create mode 100644 sound/pci/hda/cs35l56_hda.h create mode 100644 sound/pci/hda/cs35l56_hda_i2c.c create mode 100644 sound/pci/hda/cs35l56_hda_spi.c -- 2.30.2

Failed to import use case configuration

alsa-project/alsa-utils issue #217 was opened from jesusjimsa: Hello, I have stored the configuration for my sound card in an asound.state file and `alsactl` is reading it fine, but during boot and whenever I try running the command manually, this message appears in the log: ``` alsa-lib ../../../git/src/ucm/main.c:1412:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2 ``` I don't understand what is going wrong and I haven't found much online. Any ideas for how I could fix this error or what might be the origin of it? This is what I get if I run `aplay -l`: ``` ~# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: mycard [mycard], device 0: 44004000.audio-controller-tlv320aic31xx-hifi tlv320aic31xx-hifi [44004000.audio-controller-tlv320aic31xx-hifi tlv320aic31xx-hifi] Subdevices: 1/1 Subdevice #0: subdevice #0 ``` Thank you.

[PATCH AUTOSEL 4.14 01/20] ASoC: dwc: limit the number of overrun messages
