[alsa-devel] [PATCH - extplug without conversion 0/1] pcm: extplug: Use same format for slave
by twischer＠de.adit-jv.com 07 Dec '18

07 Dec '18

Hi Takashi, I have the following new idea for [PATCH - extplug refinement from hw_params 1/1] pcm: extplug: Update slave PCM if extplug slave params were changed May be you could give a short feedback. I will try to provide a reproduction scenario. Do you have an idea how to handle this additional function parameter without breaking the API. Best regards Timo

[alsa-devel] [PATCH - extplug refinement from hw_params 1/1] pcm: extplug: Update slave PCM if extplug slave params were changed
by twischer＠de.adit-jv.com 07 Dec '18

07 Dec '18

From: Timo Wischer <twischer(a)de.adit-jv.com> from extplug hw_params() callback function. This feature is for example required in the following use case: - A filter plugin supports only 1-8 channels. Therefore it calls snd_pcm_extplug_set_slave_param_minmax(SND_PCM_EXTPLUG_HW_CHANNELS, 1, 8) to provide the salve PCM parameters limited to 1-8 channels to the user application - The user application requests 2 channels. But in this case the slave PCM will be configured with 1 channel because it is the first valid configuration - To update the salve PCM snd_pcm_extplug_set_slave_param_minmax(SND_PCM_EXTPLUG_HW_CHANNELS, 2, 2) could be called from the extplug hw_params() callback function Without this patch the call to snd_pcm_extplug_set_slave_param_minmax() would not have any effect. With this patch the slave device will also be configured with 2 channels and no down mixing has to be done by the extplug. This new feature can also be used for some specific dependencies. For example a down mixing extplug supports only 2to1 and 4to2 channel down mixing. Therefore the salve PCM has to be opened with 2 channels if the user application requests 4 channels.

[alsa-devel] Applied "ASoC: max9867: Remove useless assignment" to the asoc tree

07 Dec '18

The patch ASoC: max9867: Remove useless assignment has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

[alsa-devel] Applied "ASoC: max9867: Fix signal paths" to the asoc tree
by Mark Brown 07 Dec '18

07 Dec '18

The patch ASoC: max9867: Fix signal paths has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From bc2610a6c4c92f0bf6bbf4c6641407536f30daaf Mon Sep 17 00:00:00 2001 From: Ladislav Michl <ladis(a)linux-mips.org> Date: Tue, 4 Dec 2018 19:21:33 +0100 Subject: [PATCH] ASoC: max9867: Fix signal paths Sound capture and line bypass currently do not work as well as some mixer controls.

Well, this seems more deeper than I thought. Below is my quick attempt to add the infrastructure. This adds more flexibility but still easiness for other possible button implementations, hopefully. Could you check the series below? thanks, Takashi

[alsa-devel] [PATCH 0/4] alsa-utils: axfer: add help texts
by GitHub pull_request - opened 07 Dec '18

07 Dec '18

alsa-project/alsa-utils pull request #7 was opened from takaswie: This patchset adds help texts for command entry, list and transfer subcommands. In this time, contents for each backend of transfer subcommand is not added yet. Unfortunately, execution of aliases (arecord/aplay) can print help text for command text only. This bug will be fixed in future commits. Additionally, due to program design, execution of the aliases cannot print help text of list subcommand. This is unavoidable loss of backward compatibility. ``` Takashi Sakamoto (4): axfer: print help text of command entry axfer: print help text of list subcommand axfer: print help text of transfer subcommand just for common options axfer: enable each backend to print own help axfer/main.c | 12 +++++++++++- axfer/subcmd-list.c | 9 ++++++++- axfer/xfer-libasound.c | 6 ++++++ axfer/xfer-libffado.c | 6 ++++++ axfer/xfer-options.c | 35 +++++++++++++++++++++++++++++++++++ axfer/xfer.c | 5 +++++ axfer/xfer.h | 2 ++ 7 files changed, 73 insertions(+), 2 deletions(-) ``` Request URL : https://github.com/alsa-project/alsa-utils/pull/7 Patch URL : https://github.com/alsa-project/alsa-utils/pull/7.patch Repository URL: https://github.com/alsa-project/alsa-utils

[alsa-devel] ALC700 headphone no sound issue

Hi Takashi, In Intel ENG board with ALC700. It had headphone no sound issue. If it plugged headphone or headset into the jack, then do the reboot, it will have a chance to cause headphone no sound. It just need to run the headphone mode procedure after boot time. The issue will be fixed. It also suitable for ALC234 ALC274 and ALC294. BR, Kailang
