Subject: [PATCH] ASoC: amd: Fix for Subsequent Playback issue.
Date: Mon, 27 Jan 2020 16:56:03 +0530
Message-ID: <1580124397-19842-1-git-send-email-Vishnuvardhanrao.Ravulapati@amd.com> (raw)

If we play audio back to back, which kills one playback
and immediately start another, we can hear clicks.
This patch fixes the issue.
