Subject: [PATCH] ALSA: hda - using POS_FIX_LPIB on Broadwell HDMI Audio
Date: Thu,  8 May 2014 02:03:24 +0800	[thread overview]
Message-ID: <1399485804-75028-1-git-send-email-libin.yang@intel.com> (raw)

From: Libin Yang <libin.yang@intel.com>

Audio stream is not continuous if using position buffer on Broadwell
HDMI audio. Sound is clipped.
