From f0220575e65abe09c09cd17826a3cdea76e8d58f Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Fri, 27 Oct 2023 11:57:46 +0100 Subject: ASoC: soc-dai: add flag to mute and unmute stream during trigger In some setups like Speaker amps which are very sensitive, ex: keeping them unmute without actual data stream for very short duration results in a static charge and results in pop and clicks. To minimize this, provide a way to mute and unmute such codecs during trigger callbacks.
