From 9b9e22731c137ef3f3febde7d4a914e1adfe6253 Mon Sep 17 00:00:00 2001

Subject: SWCODEC: Fix the problem of  replaygain not being applied unless the
 menu is entered. Make all codecs set the replay gain or else formats that do
 not have replaygain will not set the gain back to default if a file with gain
 applied proceeded them.
