[PATCH] ASoC: ops: Fix wraparound for mask in snd_soc_get_volsw
by Stephen Lee 29 Mar '24

29 Mar '24

In snd_soc_info_volsw(), mask is generated by figuring out the index of the most significant bit set in max and converting the index to a bitmask through bit shift 1. Unintended wraparound occurs when max is an integer value with msb bit set. Since the bit shift value 1 is treated as an integer type, the left shift operation will wraparound and set mask to 0 instead of all 1's. In order to fix this, we type cast 1 as `1ULL` to prevent the wraparound.

[PATCH] soundwire: qcom: Convert to platform remove callback returning void
by Uwe Kleine-König 28 Mar '24

28 Mar '24

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

[PATCH 0/7] Soundwire: clean up sysfs group creation
by Greg Kroah-Hartman 28 Mar '24

28 Mar '24

Note, this is a redone version of a very old series I wrote back in 2022: https://lore.kernel.org/r/20220824135951.3604059-1-gregkh@linuxfoundation.o… but everyone has forgotten about it now, and I've reworked it, so I'm considering it a "new" version, and not v2. Here's a series that adds the functionality to the driver core to hide entire attribute groups, in a much saner way than we have attempted in the past (i.e. dynamically figuring it out.) Many thanks to Dan for this patch. I'll also be taking this into my driver-core branch and creating a stable tag for anyone else to pull from to get it into their trees, as I think it will want to be in many for this development cycle. After the driver core change, there's cleanups to the soundwire core for how the attribute groups are created, to remove the "manual" creation of them, and allow the driver core to create them correctly, as needed, when needed, which makes things much smaller for the soundwire code to manage. Comments appreciated! thanks, greg k-h Dan Williams (1): sysfs: Introduce a mechanism to hide static attribute_groups Greg Kroah-Hartman (5): soundwire: sysfs: move sdw_slave_dev_attr_group into the existing list of groups soundwire: sysfs: cleanup the logic for creating the dp0 sysfs attributes soundwire: sysfs: have the driver core handle the creation of the device groups soundwire: sysfs: remove sdw_slave_sysfs_init() soundwire: sysfs: remove unneeded ATTRIBUTE_GROUPS() comments drivers/soundwire/bus_type.c | 5 ++- drivers/soundwire/sysfs_local.h | 4 +- drivers/soundwire/sysfs_slave.c | 64 ++++++++++++++--------------- drivers/soundwire/sysfs_slave_dpn.c | 3 ++ fs/sysfs/group.c | 45 ++++++++++++++++---- include/linux/sysfs.h | 63 ++++++++++++++++++++++------ 6 files changed, 126 insertions(+), 58 deletions(-) -- 2.43.0

[PATCH 0/3] ASoC: Use snd_ctl_find_id_mixer() instead of open-coding
by Richard Fitzgerald 28 Mar '24

28 Mar '24

The first two patches change snd_soc_card_get_kcontrol() to use the core snd_ctl_find_id_mixer() functionality instead of open-coding its own list walk. The last patch adds a KUnit test for this, which was tested on the original and modified code. Richard Fitzgerald (3): ALSA: control: Introduce snd_ctl_find_id_mixer_locked() ASoC: soc-card: Use snd_ctl_find_id_mixer() instead of open-coding ASoC: soc-card: Add KUnit test case for snd_soc_card_get_kcontrol include/sound/control.h | 23 +++++ sound/soc/Kconfig | 8 ++ sound/soc/Makefile | 4 + sound/soc/soc-card-test.c | 191 ++++++++++++++++++++++++++++++++++++++ sound/soc/soc-card.c | 21 +---- 5 files changed, 230 insertions(+), 17 deletions(-) create mode 100644 sound/soc/soc-card-test.c -- 2.39.2

Dummy output with ES8326 codec

alsa-project/alsa-ucm-conf issue #407 was opened from Henrythek: ## Description During the process of using the ES8326 codec, I encountered a dummy output issue. killall pulseaudio do not work, even after masking and then unmasking the pulseaudio service and attempting to restart it, the issue persists. The dummy output occurs intermittently when plugging in or unplugging headphones, and rebooting can temporarily resolve the issue. I am using the following configuration: - Operating System: Debian GNU/Linux 12 - Kernel Version: 6.7.0 ## Error Messages E: [pulseaudio] module-alsa-card.c: Failed to find a working profile. E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="0" name="pci-0000_00_1f.3-platform-sof-essx8336" card_name="alsa_card.pci-0000_00_1f.3-platform-sof-essx8336" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes avoid_resampling=no card_properties="module-udev-detect.discovered=1""): initialization failed. I: [pulseaudio] module-udev-detect.c: Card /devices/pci0000:00/0000:00:1f.3/sof-essx8336/sound/card0 (alsa_card.pci-0000_00_1f.3-platform-sof-essx8336) failed to load module. ## Additional Information The UCM (Use Case Manager) configuration used is from the following repository: [alsa-ucm-conf/ucm2/Intel/sof-essx8336](https://github.com/alsa-project/alsa… ## Steps to Reproduce 1. Use the ES8326 codec on a Debian GNU/Linux 12 system with Kernel 6.7.0. 2. Attempt to use the audio functionality. 3. Plug in or unplug headphones. 4. Observe the dummy output issue and the error messages mentioned above. ## Additional Context [alsa-info.txt](https://github.com/alsa-project/alsa-ucm-conf/files/14782974… [aplay.txt](https://github.com/alsa-project/alsa-ucm-conf/files/14782975/apl… [pulseaudio_v.txt](https://github.com/alsa-project/alsa-ucm-conf/files/14782… ![Screenshot from 2024-03-27 21-44-34](https://github.com/alsa-project/alsa-ucm-conf/assets/68213530/925… Issue URL : https://github.com/alsa-project/alsa-ucm-conf/issues/407 Repository URL: https://github.com/alsa-project/alsa-ucm-conf
