Does anyone know what the difference is between the audio settings: Hi Fi, and Home Cinema?

It makes sense that HC would be multi-channel, but there's no telling what the dynamic range etc of that is compared to Hi Fi.

Some internet discussions seem to think hifi outputs 2.0, but the remark was more of a guess than an informed statement. DICE also never specified whether hifi uses any DSP techniques (such as dolby virtual speakers / dolby headphones) to mix multi-channel sounds into a virtual surround sound.

On the other hand.. downloading Armoured Kill at the moment... geez these updates a huge..
