Add bass redirection controls for surround outputs. This uses the DSP to redirect audio below the bass redirection crossover frequency to the LFE channel from the front/rear L/R speakers. This only goes into effect if the speakers aren't set as full range, and only if the surround configuration has an LFE channel.
