[PATCH 0/2] ASoC: intel: use asoc_substream_to_rtd()

Hi Mark I have posted "ASoC: add asoc_substream_to_rtd() macro" patch-set to ALSA SoC ML (= see Link), and then Pierre-Louis wanted that Intel patch was separated for boards.

[PATCH] ASoC: dt-bindings: q6asm: Add Q6ASM_DAI_{TX_RX, TX, RX} defines
by Stephan Gerhold 27 Jul '20

27 Jul '20

Right now the direction of a DAI has to be specified as a literal number in the device tree, e.g.: dai@0 { reg = <0>; direction = <2>; }; but this does not make it immediately clear that this is a playback/RX-only DAI. Actually, q6asm-dai.c has useful defines for this. Move them to the dt-bindings header to allow using them in the dts(i) files. The example above then becomes: dai@0 { reg = <0>; direction = <Q6ASM_DAI_RX>; }; which is immediately recognizable as playback/RX-only DAI.

[PATCH] ASoC: AMD: Restore PME_EN state at Power On
by Akshu Agrawal 27 Jul '20

27 Jul '20

PME_EN state needs to restored to the value set by fmw. For the devices which are not using I2S wake event which gets enabled by PME_EN bit, keeping PME_EN enabled burns considerable amount of power as it blocks low power state. For the devices using I2S wake event, PME_EN gets enabled in fmw and the state should be maintained after ACP Power On.

[PATCH] alsaucm: Fix ending with quotes commands
by Cheng Yueh 27 Jul '20

If we use 'alsaucm -n -b -' with 'get "CapturePCM/Internal Mic"' then the alsaucm will report error and stop immediately.

snd_soc_component_driver substream ops
by Daniel Baluta 27 Jul '20

27 Jul '20

Hi Morimoto-san, Looking at snd_soc_component_driver I see there are some operations like: open, close, hw_params, hw_free. (1) Now, snd_soc_component_driver has snd_compress_ops. Do you think it is worth it to group operations from (1) in a similar structure maybe snd_<xyz>_ops. Daniel.

Acer TravelMate 5735Z (Realtek ALC272X): Periodic crackling noises
by Paul Menzel 27 Jul '20

27 Jul '20

Dear Linux folks, On Acer TravelMate 5735Z with Debian Sid/unstable and Linux 5.7.6, there are recurring crackling noises on the internal speaker. I ran `alsa-info` from the Debian package, and the logs are uploaded [1]. It’d be awesome, if you took a look, and told me, what I can try to solve this. Kind regards, Paul [1]: https://alsa-project.org/db/?f=67bde144f2e2a4f06da89a8cc8abf93da8c91d5b
