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 defbf708baf2a4cc4421699d02b57d7c3bb728b0 Mon Sep 17 00:00:00 2001 From: Zidan Wang Date: Fri, 8 Jan 2016 16:57:01 +0800 Subject: [PATCH] ASoC: wm8960: add DAC mono mix kcontrol In normal operation, the left and right channel digital audio data is converted to analogue in two separate DACs. There is a mono-mix mode where the two audio channels are mixed together digitally and then converted to analogue using only one DAC, while the other DAC is switched off. The mono-mix signal can be selected to appear on both analogue output channels. The mono mix is automatically attenuated by 6dB to prevent clipping.
