Subject: [PATCH v2 04/13] ALSA: hdac: couple the hda DMA stream in cleanup
Date: Sat, 12 Dec 2015 17:36:24 +0530	[thread overview]
Message-ID: <1449921993-21101-5-git-send-email-vinod.koul@intel.com> (raw)
In-Reply-To: <1449921993-21101-1-git-send-email-vinod.koul@intel.com>

From: Jeeja KP <jeeja.kp@intel.com>

A stream is by default in coupled mode, in DSP operation we move
it to decoupled mode. On cleanup HW expects that we leave it back
to default state so couple the DMA on cleanup.
