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
