From e2340465ec9587362a057524d3e2163377366771 Mon Sep 17 00:00:00 2001 From: Paul Vojta Date: Fri, 27 Jul 2007 12:20:38 +0200 Subject: [PATCH] [ALSA] Fix bugs in mode change/recalibration for opl3sa2 driver The mode change / recalibration doesn't work always with opl3sa2 devices, e.g. the first time it's played back. The patch fixes the problem.
