[PATCH] ASoC: rk817: Add module alias for rk817-codec
by Nicolas Frattaroli 23 Nov '21

23 Nov '21

Without a module alias, autoloading the driver does not occurr when it is built as a module. By adding a module alias, the driver now probes fine automatically and therefore analog audio output works as it should.

[PATCH] ASoC: SOF: sof-pci-dev: use community key on all Up boards
by Pierre-Louis Bossart 23 Nov '21

23 Nov '21

There are already 3 versions of the Up boards with support for the SOF community key (ApolloLake, WhiskyLake, TigerLake). Rather than continue to add quirks for each version, let's add a wildcard. For WHL and TGL, the authentication supports both the SOF community key and the firmware signed with the Intel production key. Given two choices, the community key is the preferred option to allow developers to sign their own firmware. The firmware signed with production key can still be selected if needed with a kernel module option (snd-sof-pci.fw_path="intel/sof") Tested-by: Péter Ujfalusi <peter.ujfalusi(a)linux.intel.com> Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> Reviewed-by: Bard Liao <yung-chuan.liao(a)linux.intel.com> Reviewed-by: Péter Ujfalusi <peter.ujfalusi(a)linux.intel.com> --- sound/soc/sof/sof-pci-dev.c | 10 +--------- 1 file changed, 1 insertion(+), 9 deletions(-) diff --git a/sound/soc/sof/sof-pci-dev.c b/sound/soc/sof/sof-pci-dev.c index bc9e70765678..b4bc4f887b43 100644 --- a/sound/soc/sof/sof-pci-dev.c +++ b/sound/soc/sof/sof-pci-dev.c @@ -64,17 +64,9 @@ static const struct dmi_system_id sof_tplg_table[] = { static const struct dmi_system_id community_key_platforms[] = { { - .ident = "Up Squared", + .ident = "Up boards", .matches = { DMI_MATCH(DMI_SYS_VENDOR, "AAEON"), - DMI_MATCH(DMI_BOARD_NAME, "UP-APL01"), - } - }, - { - .ident = "Up Extreme", - .matches = { - DMI_MATCH(DMI_SYS_VENDOR, "AAEON"), - DMI_MATCH(DMI_BOARD_NAME, "UP-WHL01"), } }, { -- 2.25.1

[PATCH 00/10] ASoC: SOF: enable multicore with dynamic pipelines
by Kai Vehmanen 23 Nov '21

23 Nov '21

Hi, initial support for SOF dynamic pipelines was added in commit 5fcdbb2d45df ("ASoC: SOF: Add support for dynamic pipelines"). When a pipeline is marked dynamic in the SOF DSP firmware topology definition (the tplg file kernel loads from filesystem), it means the pipeline resources are not allocated when DSP is booted (at driver probe, or at runtime resume), but rather delayed until the pipeline is actually used. Until now, it has not been possible to use multiple DSP cores in a topology that uses dynamic pipeline capability. This patchset addresses this gap and allows to freely mix dynamic pipelines and multicore usages in topology definitions. The series was originally reviewed in https://github.com/thesofproject/linux/pull/3019 Ranjani Sridharan (10): ASoC: SOF: Intel: hda: expose get_chip_info() ASoC: SOF: Introduce num_cores and ref count per core ASoC: SOF: Add ops for core_get and core_put ASoC: SOF: Intel: TGL: set core_get/put ops ASoC: SOF: Intel: CNL/ICL/APL: set core_get/core_put ops ASoC: SOF: topology: remove sof_load_pipeline_ipc() ASoC: SOF: free widgets in sof_tear_down_pipelines() for static pipelines ASoC: SOF: hda: don't use the core op for power up/power down ASoC: SOF: add support for dynamic pipelines with multi-core ASoC: SOF: Intel: hda: free DAI widget during stop and suspend sound/soc/sof/imx/imx8.c | 1 + sound/soc/sof/imx/imx8m.c | 1 + sound/soc/sof/intel/apl.c | 5 +- sound/soc/sof/intel/bdw.c | 9 +++ sound/soc/sof/intel/byt.c | 9 +++ sound/soc/sof/intel/cnl.c | 5 +- sound/soc/sof/intel/hda-dai.c | 23 +------ sound/soc/sof/intel/hda-dsp.c | 52 +++++++++++++++- sound/soc/sof/intel/hda-loader.c | 24 +++++--- sound/soc/sof/intel/hda.c | 17 ++---- sound/soc/sof/intel/hda.h | 1 + sound/soc/sof/intel/icl.c | 5 +- sound/soc/sof/intel/pci-tng.c | 9 +++ sound/soc/sof/intel/shim.h | 7 +++ sound/soc/sof/intel/tgl.c | 46 +++++++++++++- sound/soc/sof/ops.h | 71 ++++++++++++++++------ sound/soc/sof/sof-audio.c | 83 +++++++++++++++++++------ sound/soc/sof/sof-audio.h | 6 -- sound/soc/sof/sof-priv.h | 21 +++++-- sound/soc/sof/topology.c | 100 ------------------------------- 20 files changed, 294 insertions(+), 201 deletions(-) base-commit: 626a3dfbdb5d11f92e709680135abf272057ef59 -- 2.33.0

[PATCH] ASoC: cs42l42: Report initial jack state
by Richard Fitzgerald 23 Nov '21

23 Nov '21

When a jack handler is registered in cs42l42_set_jack() the initial state should be reported if an attached headphone/headset has already been detected. The jack detect sequence takes around 1 second: typically long enough for the machine driver to probe and register the jack handler in time to receive the first report from the interrupt handler. So it is possible on some systems that the correct initial state was seen simply because of lucky timing. Modular builds were more likely to miss the reporting of the initial state.

[PATCH 5.16 regression fix] ASoC: soc-acpi: Set mach->id field on comp_ids matches
by Hans de Goede 23 Nov '21

23 Nov '21

Commit dac7cbd55dca ("ASoC: Intel: soc-acpi-byt: shrink tables using compatible IDs") and commit 959ae8215a9e ("ASoC: Intel: soc-acpi-cht: shrink tables using compatible IDs") simplified the match tables in soc-acpi-intel-byt-match.c and soc-acpi-intel-cht-match.c by merging identical entries using the new .comp_ids snd_soc_acpi_mach field to point a single entry to multiple ACPI HIDs and clearing the previously unique per entry .id field. But various machine drivers from sound/soc/intel/boards rely on mach->id in one or more ways, e.g. some drivers contain the following snippets: adev = acpi_dev_get_first_match_dev(mach->id, NULL, -1); pkg_found = snd_soc_acpi_find_package_from_hid(mach->id, ... if (!strncmp(snd_soc_cards[i].codec_id, mach->id, 8)) { ... All of which are broken by the match table shrinking. Make the snd_soc_acpi_mach.id field non const (the storage for the tables already is non const) and on a comps_ids match copy the matching HID to the id field to fix this.

Xonar U7 MKII Analog Multichannel and SPDIF
by GitHub issues - opened 21 Nov '21

21 Nov '21

alsa-project/alsa-lib issue #194 was opened from Gebbx: Hi, Usb sound card Xonar U7 MKII plays multichannel content without issue, but only through aplay `aplay -D hw:2,0 test.wav #6 channels file` in other cases only two channels work (downmixed) I have tried different combinations of settings. Editing asound.conf gives no results too. The digital output also does not work in any combination of settings, but works (only two channels) in the following case: `pcm_slave.u7spdif { pcm "hw:2,1" } pcm.u7spplug { type plug slave u7spdif hint { show on } }` If I understand correctly, in this case it output the decoded signal and it will always be two-channel. I found a topic: https://forum.kodi.tv/showthread.php?tid=253179 So, i have to edit USB-Audio.conf, ``` USB-Audio.pcm.iec958_device { # "NoiseBlaster 3000" 42 "USB Sound Blaster HD" 1 "Xonar U7" 1 "MKII" 1 # my card } ``` but this is not recommended. How can this be done in another way? Example given in the USB-Audio.conf file forces system to reboot. `cards.USB-Audio.pcm.iec958_device."MKII" 1` Thanks!
