The limitations are what is connected to the SOC pins on the motherboardand and what is programmed to operate. Lineout is available on external connector pins 27 and 28 as used by the Griffin dock, but must be hardware enabled. I’m currently working on a lineout cable to plug in without opening the player and modding it. I can get lineout with an internal pullup jump. Switching the headphone jack to lineout would require some heavy hardware modding with switching transistors and trace rerouting. I doubt the speaker out has any connections on the fuze as it would ■■■■ the battery down quickly with the 500ma output.
Would be nice if someone built a player with the full capability of this chip, but it will need well written firmware to run correctly. Maybe Sandisk can hire a firmware writer from iRiver to do it.
