bit 5 LOSEL

LINE_OUT Amplifiers Input Select.
This bit allows the LINE_OUT output amplifiers to be driven by the mixer or the surround DACs. The main purpose for this is to allow swapping of the front and surround channels to make better use of the SURR/HP_OUT output amplifiers. This bit should normally be used in tandem with the HPSEL bit (see below).

0 = LINE_OUT amplifiers are driven by the mixer outputs (reset default).
1 = LINE_OUT amplifiers are driven by the surround DAC outputs.
