2024-11-13ALSA: us122l: Drop mmap_count fieldTakashi Iwai
us122l.mmap_count field was used for counting the hwdep mmap opens and syncing at disconnection. But such a manual sync isn't needed, as the refcount check is done in the ALSA core side. So let's drop it. Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20241113111042.15058-4-tiwai@suse.de
2024-11-13ALSA: us122l: Use snd_card_free_when_closed() at disconnectionTakashi Iwai
The USB disconnect callback is supposed to be short and not too-long waiting. OTOH, the current code uses snd_card_free() at disconnection, but this waits for the close of all used fds, hence it can take long. It eventually blocks the upper layer USB ioctls, which may trigger a soft lockup. An easy workaround is to replace snd_card_free() with snd_card_free_when_closed(). This variant returns immediately while the release of resources is done asynchronously by the card device release at the last close. The loop of us122l->mmap_count check is dropped as well. The check is useless for the asynchronous operation with *_when_closed().

2024-11-04ALSA: ump: Don't enumeration invalid groups for legacy rawmidiTakashi Iwai
The legacy rawmidi tries to enumerate all possible UMP groups belonging to the UMP endpoint. But currently it shows all 16 ports when the UMP endpoint is configured with static blocks, although most of them may be unused. There was already a fix for the sequencer client side to ignore such groups in the commit 3bfd7c0ba184 ("ALSA: seq: ump: Skip useless ports for static blocks"), and this commit is a similar fix for UMP rawmidi devices; it adds simply the check for the validity of each group that has been already parsed. (Note that the group info was moved to snd_ump_endpoint.groups[] by the commit 0642a3c5cacc0321c755 ("ALSA: ump: Update substream name from assigned FB names")).

2024-10-31Revert "ALSA: hda/conexant: Mute speakers at suspend / shutdown"Jarosław Janik
Commit 4f61c8fe3520 ("ALSA: hda/conexant: Mute speakers at suspend / shutdown") mutes speakers on system shutdown or whenever HDA controller is suspended by PM; this however interacts badly with Thinkpad's ACPI firmware behavior which uses beeps to signal various events (enter/leave suspend or hibernation, AC power connect/disconnect, low battery, etc.); now those beeps are either muted altogether (for suspend/hibernate/ shutdown related events) or work more or less randomly (eg. AC plug/unplug is only audible when you are playing music at the moment, because HDA device is likely in suspend mode otherwise). Since the original bug report mentioned in 4f61c8fe3520 complained about Lenovo's Thinkpad laptop - revert this commit altogether.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below sound to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

The WD19 family of docks has the same audio chipset as the WD15. This change enables jack detection on the WD19. We don't need the dell_dock_mixer_init quirk for the WD19. It is only needed because of the dell_alc4020_map quirk for the WD15 in mixer_maps.c, which disables the volume controls.

2024-10-29wcd937x codec fixesMark Brown
Merge series from Alexey Klimov <alexey.klimov@linaro.org>: This sent as RFC because of the following: - regarding the LO switch patch. I've got info about that from two persons independently hence not sure what tags to put there and who should be the author. Please let me know if that needs to be corrected. - the wcd937x pdm watchdog is a problem for audio playback and needs to be fixed. The minimal fix would be to at least increase timeout value but it will still trigger in case of plenty of dbg messages or other delay-generating things. Unfortunately, I can't test HPHL/R outputs hence the patch is only for AUX. The other options would be introducing module parameter for debugging and using HOLD_OFF bit for that or adding Kconfig option.

2024-10-29ASoC: codecs: wcd937x: relax the AUX PDM watchdogAlexey Klimov
On a system with wcd937x, rxmacro and Qualcomm audio DSP, which is pretty common set of devices on Qualcomm platforms, and due to the order of how DAPM widgets are powered on (they are sorted), there is a small time window when wcd937x chip is online and expects the flow of incoming data but rxmacro is not yet online. When wcd937x is programmed to receive data via AUX port then its AUX PDM watchdog is enabled in wcd937x_codec_enable_aux_pa(). If due to some reasons the rxmacro and soundwire machinery are delayed to start streaming data, then there is a chance for this AUX PDM watchdog to reset the wcd937x codec. Such event is not logged as a message and only wcd937x IRQ counter is increased however there could be a lot of other reasons for that IRQ. There is a similar opportunity for such delay during DAPM widgets power down sequence. If wcd937x codec reset happens on the start of the playback, then there will be no sound and if such reset happens at the end of a playback then it may generate additional clicks and pops noises. On qrb4210 RB2 board without any debugging bits the wcd937x resets are sometimes observed at the end of a playback though not always. With some debugging messages or with some tracing enabled the AUX PDM watchdog resets the wcd937x codec at the start of a playback and there is no sound output at all. In this patch: - TIMEOUT_SEL bit in PDM_WD_CTL2 register is set to increase the watchdog reset delay to 100ms which eliminates the AUX PDM watchdog IRQs on qrb4210 RB2 board completely and decreases the number of unwanted clicks noises; - HOLD_OFF bit postpones triggering such watchdog IRQ till wcd937x codec reset which usually happens at the end of a playback. This allows to actually output some sound in case of debugging.

2024-10-25ASoC: Intel: bytcr_rt5640: Add DMI quirk for Vexia Edu Atla 10 tabletHans de Goede
The Vexia Edu Atla 10 tablet mostly uses the BYTCR tablet defaults, but as happens on more models it is using IN1 instead of IN3 for its internal mic and JD_SRC_JD2_IN4N instead of JD_SRC_JD1_IN4P for jack-detection. Add a DMI quirk for this to fix the internal-mic and jack-detection.

2024-10-25ASoC: Intel: bytcr_rt5640: Add support for non ACPI instantiated codecHans de Goede
On some x86 Bay Trail tablets which shipped with Android as factory OS, the DSDT is so broken that the codec needs to be manually instantatiated by the special x86-android-tablets.ko "fixup" driver for cases like this. This means that the codec-dev cannot be retrieved through its ACPI fwnode, add support to the bytcr_rt5640 machine driver for such manually instantiated rt5640 i2c_clients. An example of a tablet which needs this is the Vexia EDU ATLA 10 tablet, which has been distributed to schools in the Spanish Andalucía region.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v6.12 An uncomfortably large set of fixes due to me not getting round to sending them for longer than I should due to travel and illness. This is mostly smaller driver specific changes, but there are a couple of generic changes: - Bumping the minimal topology ABI we check for during validation, the code had support for v4 removed previously but the update of the define used for initial validation was missed. - Fix the assumption that DAPM structs will be embedded in a component which isn't true for card widgets when doing name comparisons, though fortunately this is rarely triggered. We've pulled in one Soundwire fix which was part of a larger series fixing cleanup issues in on Intel Soundwire systems.

2024-10-22ASoC: qcom: sc7280: Fix missing Soundwire runtime stream allocKrzysztof Kozlowski
Commit 15c7fab0e047 ("ASoC: qcom: Move Soundwire runtime stream alloc to soundcards") moved the allocation of Soundwire stream runtime from the Qualcomm Soundwire driver to each individual machine sound card driver, except that it forgot to update SC7280 card. Just like for other Qualcomm sound cards using Soundwire, the card driver should allocate and release the runtime. Otherwise sound playback will result in a NULL pointer dereference or other effect of uninitialized memory accesses (which was confirmed on SDM845 having similar issue).

2024-10-22ASoC: fsl_micfil: Add sample rate constraintShengjiu Wang
On some platforms, for example i.MX93, there is only one audio PLL source, so some sample rate can't be supported. If the PLL source is used for 8kHz series rates, then 11kHz series rates can't be supported. So add constraints according to the frequency of available clock sources, then alsa-lib will help to convert the unsupported rate for the driver.

2024-10-21ALSA: hda/tas2781: select CRC32 instead of CRC32_SARWATEEric Biggers
Fix the kconfig option for the tas2781 HDA driver to select CRC32 rather than CRC32_SARWATE. CRC32_SARWATE is an option from the kconfig 'choice' that selects the specific CRC32 implementation. Selecting a 'choice' option seems to have no effect, but even if it did work, it would be incorrect for a random driver to override the user's choice. CRC32 is the correct option to select for crc32() to be available.

2024-10-21ALSA: hda/realtek: Add subwoofer quirk for Acer Predator G9-593José Relvas
The Acer Predator G9-593 has a 2+1 speaker system which isn't probed correctly. This patch adds a quirk with the proper pin connections. Note that I do not own this laptop, so I cannot guarantee that this fixes the issue. Testing was done by other users here: https://discussion.fedoraproject.org/t/-/118482 This model appears to have two different dev IDs... - 0x1177 (as seen on the forum link above) - 0x1178 (as seen on https://linux-hardware.org/?probe=127df9999f) I don't think the audio system was changed between model revisions, so the patch applies for both IDs.

The step variable is initialized to zero. It is changed in the loop, but if it's not changed it will remain zero. Add a variable check before the division. The observed behavior was introduced by commit 826b5de90c0b ("ALSA: firewire-lib: fix insufficient PCM rule for period/buffer size"), and it is difficult to show that any of the interval parameters will satisfy the snd_interval_test() condition with data from the amdtp_rate_table[] table.
