// us fall back the silence generator. The basic problem is that AUDIO_DECODER may refer to
// either #3 or #4 (and may changed based on the victor of boot time races) and that, for some BD-ROM
// deployments, #4 doesn't support DTS. This results in the eroneous adoption of the silence generator.
// Our solution is to temporarily change the transformer names to allow the codec to initialize. We then
// switch them back again in order to prevent the system breaking during a later call to
// SetModuleParameters(CodecSpecifyTransformerPostFix...).
