[PATCH 1/2] ALSA: usb-audio: Fix potential out-of-bounds shift
by Takashi Iwai 09 Dec '20

09 Dec '20

syzbot spotted a potential out-of-bounds shift in the USB-audio format parser that receives the arbitrary shift value from the USB descriptor. Add a range check for avoiding the undefined behavior.

[PATCH 0/5] ALSA: hda/ca0132 - Fix no-audio issues and add documentation.
by Connor McAdams 09 Dec '20

09 Dec '20

This patch series attempts to fix the no audio at startup issues that have been occurring for some users, using information gained through reverse engineering the ca0132's onboard 8051 processor. The issue of no audio on startup seemed to be caused by two separate problems: not resetting the codec upon initialization, and not making sure the DSP allocates it's DMA channels correctly. Tested and working on all cards, except for the AE-7. The AE-7 shouldn't have any issues, however, I don't have one on hand to test. As an aside, I'm not sure how to classify which commits this necessarily 'fixes', as it's covering multiple areas. Please let me know if this is necessary. Connor McAdams (5): ALSA: hda/ca0132 - Reset codec upon initialization. ALSA: hda/ca0132 - Add stream port remapping function. ALSA: hda/ca0132 - Add 8051 exram helper functions. ALSA: hda/ca0132 - Ensure DSP is properly setup post-firmware download. ALSA: hda/ca0132 - Remove now unnecessary DSP setup functions. sound/pci/hda/patch_ca0132.c | 567 ++++++++++++++++++++++------------- 1 file changed, 363 insertions(+), 204 deletions(-) -- 2.25.1

[PATCH] ASoC: AMD Renoir - add DMI table to avoid the ACP mic probe (broken BIOS)
by Jaroslav Kysela 08 Dec '20

08 Dec '20

Users reported that some Lenovo AMD platforms do not have ACP microphone, but the BIOS advertises it via ACPI. This patch create a simple DMI table, where those machines with the broken BIOS can be added. The DMI description for Lenovo IdeaPad 5 and IdeaPad Flex 5 devices are added there. Also describe the dmic_acpi_check kernel module parameter in a more understandable way.

[PATCH] ASoC: AMD Raven/Renoir - fix the PCI probe (PCI revision)
by Jaroslav Kysela 08 Dec '20

08 Dec '20

The Raven and Renoir ACP can be distinguished by the PCI revision. Let's do the check very early, otherwise the wrong probe code can be run.

[PATCH] ASoC: cx2072x: Fix doubly definitions of Playback and Capture streams
by Takashi Iwai 08 Dec '20

08 Dec '20

The cx2072x codec driver defines multiple DAIs with the same stream name "Playback" and "Capture". Although the current code works more or less as is as the secondary streams are never used, it still leads the error message like: debugfs: File 'Playback' in directory 'dapm' already present! debugfs: File 'Capture' in directory 'dapm' already present! Fix it by renaming the secondary streams to unique names.
