From 391153522d186f19a008d824bb3a05950351ce6c Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Thu, 16 Jun 2022 15:18:18 -0500 Subject: [PATCH] ASoC: SOF: Intel: disable IMR boot when resuming from ACPI S4 and S5 states MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The IMR was assumed to be preserved when suspending to S4 and S5 states, but community reports invalidate that assumption, the hardware seems to be powered off and the IMR memory content cleared. Make sure regular boot with firmware download is used for S4 and S5.
