[alsa-devel] [PATCH] alsa-lib: alsa dshare endless playback of buffer

[sutar.mounesh at gmail.com]

From: Anant Agrawal <Anant_Agrawal at 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.
