Subject: [PATCH] alsa-lib: alsa dshare endless playback of buffer
Date: Fri, 25 Nov 2016 16:43:34 +0530 [thread overview]
Message-ID: <1480072414-17398-1-git-send-email-sutar.mounesh@gmail.com> (raw)
From: Anant Agrawal <Anant_Agrawal@mentor.com>
On snd_pcm_drain() the slave PCM driven via plugin DSHARE is not filled with
silence. Result is endless playback of buffer content until pcm is closed.
In ALSA pcm dshare plugin, called do_silence method to fix the issue.
