[alsa-devel] Applied "ASoC: audio-graph-scu-card: use cpu/codec pointer on graph_dai_props" to the asoc tree
by Mark Brown 04 Dec '18

04 Dec '18

The patch ASoC: audio-graph-scu-card: use cpu/codec pointer on graph_dai_props 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.

Now, we want to merge audio-graph-card and audio-graph-scu-card. These sound cards are using silimar but not same logic on each functions. Then, of course we want to share same logic.

[alsa-devel] Applied "ASoC: max98373: Added max98373_reset for stable amp reset" to the asoc tree
by Mark Brown 04 Dec '18

04 Dec '18

The patch ASoC: max98373: Added max98373_reset for stable amp reset 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 20f2ab247d3b787af91c1aa5eb27c5061744c154 Mon Sep 17 00:00:00 2001 From: Ryan Lee <RyanS.Lee(a)maximintegrated.com> Date: Fri, 30 Nov 2018 03:21:09 +0000 Subject: [PATCH] ASoC: max98373: Added max98373_reset for stable amp reset This patch added max98373_reset function to avoid amp software reset failure and code duplication. Reset verification step has been added for stable amp reset and it repeats verification maximum 3 times when it is failed. Chip revision ID is available when the amp is in the idle state which means software reset is completed well. Additional 10ms delay was added for every retrial and maximum 30ms delay can be applied.

[alsa-devel] How to inform application about sample rate changed from device.
by Chakravarthi Pradeep 04 Dec '18

04 Dec '18

Hi All, I'm working in FPGA device, which can provide raw video and pcm data. I'm using v4l2 and alsa framework for video and audio respectively. Audio flow path is using ALSA framework and video flow path is using v4l2 framework. Device can generate different audio sample rate such as 44.1KHz, 48KHz and 96KHz. VLC can render video and audio smoothly with 48KHz of sample rate, 2 channel and video with FHD(1920x1080). When device is set with 44.1KHz and 96KHz then vlc audio is breaking.I'm using vlc version as 2.2.8 and there is no way to inform how to set the sample rate for audio device. Below are queries: 1) When device is generating audio sample rate of 44.1KHz then how to inform VLC that use 44.1KHz sample rate(same is for 96KHz) 2) what is command for vlc with video and audio device setting for width=1920 height= 1080 colorspace = RV24, channel =2,sample rate 44.1KHz. Assume video device is (/dev/video0 and audio device is hw:1.0) -- Thanks and Regards Chakravarthi Pradeep.K Ph: 91 9980434900
