21 Dec '22

alsa-project/alsa-ucm-conf issue #255 was opened from KaiChuan-Hsieh: On linux kernel 6.0, with rt715-sdca codec on Dell platform. The internal mic can't record sound after boot. Try $ amixer cset name='PGA5.0 5 Master Capture' 1 Then the internal mic can record sound successfully.

[PATCH] ALSA SoC: Texas Instruments TAS2781 Audio Smart Amp
by Kevin Lu 20 Dec '22

20 Dec '22

The TAS2781 driver implements a flexible and configurable register setting for one, two, even multiple TAS2781 chips. All the register setting are in a bin file. Almost no specific register setting can be found in the code.

[PATCH v2 0/3] ASoC: SOF: Fixes for suspend after firmware crash
by Peter Ujfalusi 20 Dec '22

20 Dec '22

Hi, This is the followup series for the v1 sent out by Ranjani [1]. Unfortunately Ranjani was dragged away to another issue and could not send the update herself. Changes since v1: - In patch 2, move the tear_down_all_pipelines call instead of duplicating it Amadeusz: I have kept the check as it is: if (tplg_ops && tplg_ops->tear_down_all_pipelines) I'm preparing the ops optionality change series which would require this change.

[PATCH 0/2] ASoC: SOF: remove unregister calls from shutdown
by Kai Vehmanen 20 Dec '22

20 Dec '22

This patchset is an alternative solution to problems reported by Ricardo Ribalda <ribalda(a)chromium.org> and Zhen Ni <nizhen(a)uniontech.com>, as discussed in - "[PATCH] ALSA: core: Fix deadlock when shutdown a frozen userspace" https://mailman.alsa-project.org/pipermail/alsa-devel/2022-November/209248.… - "[PATCH] ASoc: SOF: Fix sof-audio-pci-intel-tgl shutdown timeout during hibernation" https://mailman.alsa-project.org/pipermail/alsa-devel/2022-December/209685.… It was raised by Oliver Neukum <oneukum(a)suse.com> that kernel should not let user-space stall the shutdown process in any scenario and the unregister call in current SOF shutdown code is not right. This series reverts the ASoC SOF patch to unregister clients and the machine drivers at shutdown. To avoid bringing back old bugs, the series includes a patch to fix S5 entry on certain Intel platforms.

[PATCH 00/11] ASoC: dt-bindings: audio-graph-port related update

Hi ASoC ML, DT ML Cc Geert, Nvidia member These patches fixups audio-graph-port, and its related DT schema. Audio-Graph-Card and Simple-Audio-Card are similar Card and are sharing same utils. Thus we can also sharing same schema. Renesas and Nvidia are main user of Audio-Graph-Card. This patch-set fixup some Renesas's "make dtbs_check".
