The patch

ASoC: hdac_hdmi: Register widget event handlers

has been applied to the asoc tree at

git://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: Jeeja KP jeeja.kp@intel.com Date: Tue, 24 Jan 2017 21:49:03 +0530 Subject: [PATCH] ASoC: hdac_hdmi: Register widget event handlers

In case of hdmi connect/disconnect or when stream need to be route to multiple monitors, corresponding port and audio infoframe needs to be reconfigured. Currently all the configuration are done in DAI ops which results in silence playback.

So use dapm widget event handlers to program audio infoframe and enable /disable port configuration when widget is power on/off.
