Subject: [PATCH] ASoC: amd: Fix for Subsequent Playback issue.
Date: Tue, 21 Jan 2020 16:13:35 +0530 [thread overview]
Message-ID: <1579603421-24571-1-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.
