2025-06-27ASoC: amd: yc: Add quirk for Lenovo Yoga Pro 7 14ASP9Talhah Peerbhai
[ Upstream commit a28206060dc5848a1a2a15b7f6ac6223d869084d ] Similar to many other Lenovo models with AMD chips, the Lenovo Yoga Pro 7 14ASP9 (product name 83HN) requires a specific quirk to ensure internal mic detection. This patch adds a quirk fixing this.

2025-06-27ASoC: meson: meson-card-utils: use of_property_present() for DT parsingMartin Blumenstingl
commit 171eb6f71e9e3ba6a7410a1d93f3ac213f39dae2 upstream. Commit c141ecc3cecd ("of: Warn when of_property_read_bool() is used on non-boolean properties") added a warning when trying to parse a property with a value (boolean properties are defined as: absent = false, present without any value = true). This causes a warning from meson-card-utils. meson-card-utils needs to know about the existence of the "audio-routing" and/or "audio-widgets" properties in order to properly parse them. Switch to of_property_present() in order to silence the following warning messages during boot: OF: /sound: Read of boolean property 'audio-routing' with a value. OF: /sound: Read of boolean property 'audio-widgets' with a value.

commit 688abe2860fd9c644705b9e11cb9649eb891b879 upstream. The function sdm845_slim_snd_hw_params() calls the functuion snd_soc_dai_set_channel_map() but does not check its return value.

commit 6a3439a417b910e662c666993798e0691bc81147 upstream. The RODE AI-1 audio interface requires implicit feedback sync between playback endpoint 0x03 and feedback endpoint 0x84 on interface 3, but doesn't advertise this in its USB descriptors.

2025-06-19ALSA: core: fix up bus match const issues.Greg Kroah-Hartman
[ Upstream commit 62f134ab190c5fd5c9f68fe638ad8e13bb8a4cb4 ] In commit d69d80484598 ("driver core: have match() callback in struct bus_type take a const *"), the match bus callback was changed to have the driver be a const pointer. Unfortunately that const attribute was thrown away when container_of() is called, which is not correct and was not caught by the compiler due to how container_of() is implemented. Fix this up by correctly preserving the const attribute of the driver passed to the bus match function which requires the hdac_driver match function to also take a const pointer for the driver structure.

commit 93a81ca0657758b607c3f4ba889ae806be9beb73 upstream. The PCM OSS layer tries to clear the buffer with the silence data at initialization (or reconfiguration) of a stream with the explicit call of snd_pcm_format_set_silence() with runtime->dma_area. But this may lead to a UAF because the accessed runtime->dma_area might be freed concurrently, as it's performed outside the PCM ops. For avoiding it, move the code into the PCM core and perform it inside the buffer access lock, so that it won't be changed during the operation.

[ Upstream commit 02b44a2b2bdcee03cbb92484d31e9ca1b91b2a38 ] The volume control for cs42l43 speakers has a maximum gain of +31.5 dB. However, for many use cases, this can cause distorted audio, depending various factors, such as other signal-processing elements in the chain, for example if the audio passes through a gain control before reaching the codec or the signal path has been tuned for a particular maximum gain in the codec. In the case of systems which use the soc_sdw_cs42l43 driver, audio will likely be distorted in all cases above 0 dB, therefore add a volume limit of 128, which is 0 dB maximum volume inside this driver.

2025-05-29ALSA: usb-audio: Fix duplicated name in MIDI substream namesTakashi Iwai
[ Upstream commit 0759e77a6d9bd34a874da73721ce4a7dc6665023 ] The MIDI substream name string is constructed from the combination of the card shortname (which is taken from USB iProduct) and the USB iJack. The problem is that some devices put the product name to the iJack field, too. For example, aplaymidi -l output on the Lanchkey MK 49 are like: % aplaymidi -l Port Client name Port name 44:0 Launchkey MK4 49 Launchkey MK4 49 Launchkey MK4 44:1 Launchkey MK4 49 Launchkey MK4 49 Launchkey MK4 where the actual iJack name can't be seen because it's truncated due to the doubly words. For resolving those situations, this patch compares the iJack string with the card shortname, and drops if both start with the same words. Then the result becomes like: % aplaymidi -l Port Client name Port name 40:0 Launchkey MK4 49 Launchkey MK4 49 MIDI In 40:1 Launchkey MK4 49 Launchkey MK4 49 DAW In A caveat is that there are some pre-defined names for certain devices in the driver code, and this workaround shouldn't be applied to them. Similarly, when the iJack isn't specified, we should skip this check, too. The patch added those checks in addition to the string comparison.

Let's check it. This patch might break existing driver. In such case, let's makes each func to void instead of int.

2025-05-29ASoC: tas2764: Power up/down amp on mute opsHector Martin
[ Upstream commit 1c3b5f37409682184669457a5bdf761268eafbe5 ] The ASoC convention is that clocks are removed after codec mute, and power up/down is more about top level power management. For these chips, the "mute" state still expects a TDM clock, and yanking the clock in this state will trigger clock errors. So, do the full shutdown<->mute<->active transition on the mute operation, so the amp is in software shutdown by the time the clocks are removed. This fixes TDM clock errors when streams are stopped.

2025-05-29ASoC: mediatek: mt8188: Treat DMIC_GAINx_CUR as non-volatileNícolas F. R. A. Prado
[ Upstream commit 7d87bde21c73731ddaf15e572020f80999c38ee3 ] The DMIC_GAINx_CUR registers contain the current (as in present) gain of each DMIC. During capture, this gain will ramp up until a target value is reached, and therefore the register is volatile since it is updated automatically by hardware. However, after capture the register's value returns to the value that was written to it. So reading these registers returns the current gain, and writing configures the initial gain for every capture. >From an audio configuration perspective, reading the instantaneous gain is not really useful. Instead, reading back the initial gain that was configured is the desired behavior. For that reason, consider the DMIC_GAINx_CUR registers as non-volatile, so the regmap's cache can be used to retrieve the values, rather than requiring pm runtime resuming the device.

2025-05-29ALSA: hda/realtek: Enable PC beep passthrough for HP EliteBook 855 G7Maciej S. Szmigiero
[ Upstream commit aa85822c611aef7cd4dc17d27121d43e21bb82f0 ] PC speaker works well on this platform in BIOS and in Linux until sound card drivers are loaded. Then it stops working. There seems to be a beep generator node at 0x1a in this CODEC (ALC269_TYPE_ALC215) but it seems to be only connected to capture mixers at nodes 0x22 and 0x23. If I unmute the mixer input for 0x1a at node 0x23 and start recording from its "ALC285 Analog" capture device I can clearly hear beeps in that recording. So the beep generator is indeed working properly, however I wasn't able to figure out any way to connect it to speakers. However, the bits in the "Passthrough Control" register (0x36) seems to work at least partially: by zeroing "B" and "h" and setting "S" I can at least make the PIT PC speaker output appear either in this laptop speakers or headphones (depending on whether they are connected or not). There are some caveats, however: * If the CODEC gets runtime-suspended the beeps stop so it needs HDA beep device for keeping it awake during beeping. * If the beep generator node is generating any beep the PC beep passthrough seems to be temporarily inhibited, so the HDA beep device has to be prevented from using the actual beep generator node - but the beep device is still necessary due to the previous point. * In contrast with other platforms here beep amplification has to be disabled otherwise the beeps output are WAY louder than they were on pure BIOS setup. Unless someone (from Realtek probably) knows how to make the beep generator node output appear in speakers / headphones using PC beep passthrough seems to be the only way to make PC speaker beeping actually work on this platform.

2025-05-29ALSA: seq: Improve data consistency at pollingTakashi Iwai
[ Upstream commit e3cd33ab17c33bd8f1a9df66ec83a15dd8f7afbb ] snd_seq_poll() calls snd_seq_write_pool_allocated() that reads out a field in client->pool object, while it can be updated concurrently via ioctls, as reported by syzbot. The data race itself is harmless, as it's merely a poll() call, and the state is volatile. OTOH, the read out of poll object info from the caller side is fragile, and we can leave it better in snd_seq_pool_poll_wait() alone. A similar pattern is seen in snd_seq_kernel_client_write_poll(), too, which is called from the OSS sequencer. This patch drops the pool checks from the caller side and add the pool->lock in snd_seq_pool_poll_wait() for better data consistency.
