[PATCH] ALSA: hda: cs35l56: Enable low-power hibernation mode on i2c
by Richard Fitzgerald 11 Oct '23

11 Oct '23

From: Simon Trimmer <simont(a)opensource.cirrus.com> This can now be re-enabled as the sequence to reliably wake the device has been implemented in the shared ASoC code. This has a functional dependency on commit 3df761bdbc8b ("ASoC: cs35l56: Wake transactions need to be issued twice") To protect against this, enabling hibernation is conditional on CS35L56_WAKE_HOLD_TIME_US being defined, which indicates that the new hibernation sequences are available.

[PATCH 0/4] ASoC: makes CPU/Codec channel connection map more generic
by Kuninori Morimoto 11 Oct '23

11 Oct '23

Hi Mark Cc Bard, Pierre-Louis Current ASoC is supporting CPU/Codec = N:M (N < M) connection by using ch_map idea. This patch expand that all connection uses this idea, and no limit of N < M [1]. This patch is tested on Audio-Graph-Card2 with sample dtsi, but needs Tested-by, at least from Intel.

[PATCH] ASoC: apple: mca: Annotate struct mca_data with __counted_by
by Kees Cook 11 Oct '23

11 Oct '23

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct mca_data.

alsa-project/alsa-ucm-conf issue #359 was edited from TeamFahQ: I have Realtek ALC 4080 on an MSI MPG B650 Carbon WiFi and the chip is not getting recognized. I havve seen similar post with this exact issue on similar motherboards and the fix is to change the usb id. Unfortunately, I'm not sure which is the usb id I need `Bus 001 Device 003: ID 0db0:70d3 Micro Star International USB Audio Bus 002 Device 003: ID 0bda:0411 Realtek Semiconductor Corp. Hub Bus 001 Device 004: ID 0bda:5411 Realtek Semiconductor Corp. RTS5411 Hub` Assumably, it would be the first one I listed, but being this is a Realtek device, could it be either of the other 2?

[PATCH] hda/realtek: Add SND_PCI_QUIRK entry for the Dell XPS 9530 laptop for dual speakers
by Brett Worth 11 Oct '23

11 Oct '23

The Dell XPS 9530, like previous XPS laptops like the 9520 and 9510 have dual speakers in each channel. If the ALC289_FIXUP_DUAL_SPK flag is not set in sound/pci/hda/patch_realtek.c only the tweeter will work and therefore make the sound quality terrible. This patch has not been tested but is derived from a previous patch attempt from a different user called Pentracillin which was rejected. $ diff -r -up a b diff -r -up a/sound/pci/hda/patch_realtek.c b/sound/pci/hda/patch_realtek.c --- a/sound/pci/hda/patch_realtek.c 2023-10-07 22:16:36.129618972 +1100 +++ b/sound/pci/hda/patch_realtek.c 2023-10-07 22:16:52.645258218 +1100 @@ -9412,6 +9412,7 @@ static const struct snd_pci_quirk alc269 SND_PCI_QUIRK(0x1028, 0x0b1a, "Dell Precision 5570", ALC289_FIXUP_DUAL_SPK), SND_PCI_QUIRK(0x1028, 0x0b37, "Dell Inspiron 16 Plus 7620 2-in-1", ALC295_FIXUP_DELL_INSPIRON_TOP_SPEAKERS), SND_PCI_QUIRK(0x1028, 0x0b71, "Dell Inspiron 16 Plus 7620", ALC295_FIXUP_DELL_INSPIRON_TOP_SPEAKERS), + SND_PCI_QUIRK(0x1028, 0x0beb, "Dell XPS 15 9530", ALC289_FIXUP_DUAL_SPK), SND_PCI_QUIRK(0x1028, 0x0c03, "Dell Precision 5340", ALC269_FIXUP_DELL4_MIC_NO_PRESENCE), SND_PCI_QUIRK(0x1028, 0x0c19, "Dell Precision 3340", ALC236_FIXUP_DELL_DUAL_CODECS), SND_PCI_QUIRK(0x1028, 0x0c1a, "Dell Precision 3340", ALC236_FIXUP_DELL_DUAL_CODECS), I don't have much confidence that this patch request will meet the requirements.

[PATCH] ASoC: SOF: Convert to platform remove callback returning void
by Uwe Kleine-König 11 Oct '23

11 Oct '23

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(). The SOF platform drivers all use either sof_of_remove() or sof_acpi_remove() which both return zero unconditionally. Change these functions to return void and the drivers to use .remove_new(). There is no semantical change.
