From d73df73c556b0a225fdde7341549ed834bc691f4 Mon Sep 17 00:00:00 2001 From: Gareth Stockwell Date: Fri, 12 Mar 2010 12:58:45 +0000 Subject: Moved Symbian audio backend into QtMultimedia.dll Changed backend from being a plugin, to being statically compiled into QtMultimedia.dll. This is to achieve consistency with the backends for other plugins, and to allow the plugin API to be modified.
