[PATCH] ASoC: SOF: Kconfig: Make the SOF_DEVELOPER_SUPPORT depend on SND_SOC_SOF
by Pierre-Louis Bossart 21 Dec '21

21 Dec '21

From: Peter Ujfalusi <peter.ujfalusi(a)linux.intel.com> SND_SOC_SOF_DEVELOPER_SUPPORT contains options affecting how the built SOF driver stack will behave, enables debug options and other features. These options have no meaning if the SND_SOC_SOF is not even enabled. If we have SOF client options under developer_support and debug they can be selected to be built even without the core, but they do need symbols from the core (the sof-client API) which can result build failure. In Kconfig we can have SND_SOC_SOF_TOPLEVEL=y SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST=y for example, which will make the flood client to be built, but the SOF core is not as SND_SOC_SOF is not selected.

[PATCH 00/22] ASoC: Use dev_err_probe() helper

[PATCH] ASoC: mediatek: mt8195: correct default value
by Trevor Wu 21 Dec '21

21 Dec '21

mt8195_cg_patch is used to reset the default value of audio cg, so the register value could be consistent with CCF reference count. Nevertheless, AUDIO_TOP_CON1[1:0] is used to control an internal mux, and it's expected to keep the default value 0. This patch corrects the default value in case an unexpected behavior happens in the future.

ALSA update from 1.2.5.1 to 1.2.6.1 loses audio devices on Dell XPS 9700
by GitHub issues - opened 18 Dec '21

18 Dec '21

alsa-project/alsa-lib issue #206 was opened from roland-d: Hello, On December 16, Manjaro pushed an update which included an ALSA update from 1.2.5.1 to 1.2.6.1. This has caused users of a DELL XPS 9700 to no longer show any audio devices except the built-in speaker. This has been reported in the release post as well by a user named sparcplug. https://forum.manjaro.org/t/stable-update-2021-12-16-kernels-kde-gear-21-12… I can confirm that for me the audio devices also disappeared. A rollback to 1.2.5.1 and restart of the system brought back the sound devices. I have no idea what causes this but wanted to report it and if you need me to test I am happy to do so.
