My search found several related comments and questions but nothing related to future possibilities. The current line out supplied on the ACC connector is a buffered output of the powered speaker left and right channels. This means that if you have multiple slices open this output is a mix of all and is affected by volume adjustments. Are there any future plans to change this output so that it can be a true line out not affected by what volume is heard on the speakers? Would this require hardware changes or could it be accomplished with firmware? The best option would be the ability to associate the line out with a specific slice and have the level constant. Without this capability the radio is severely limited for any mode that requires external equipment such as hardware modems.
