From 97ed97fb560c5e40eb6dbed8b2ba01a1a4bc22ca Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Fri, 18 Jul 2008 19:04:27 -0400 Subject: [PATCH] ALSA: trident - pause s/pdif output Commit 981bcead3f2279a1ec6fb5f2c57aff79ed61a700 upstream. Stop the S/PDIF DMA engine and output when the device is told to pause. It will keep on looping the current buffer contents if this isn't done.
