Subject: [PATCH v6 08/16] ALSA: hda: cs35l41: Mute the device before shutdown
Date: Sat, 9 Apr 2022 10:13:07 +0100	[thread overview]
Message-ID: <20220409091315.1663410-9-tanureal@opensource.cirrus.com> (raw)
In-Reply-To: <20220409091315.1663410-1-tanureal@opensource.cirrus.com>

Mute the device before shutdown to avoid pops and clicks for all types
of boost.
