If you want to try this, btw, just use a Hijack kernel, and set "trace_tuner=1" in the [hijack] section.

Look at the serial port output on player startup, and the first message "in" from the tuner is "tuner: in=01000303", indicating "ID=3" regardless of what I set the knob to.

Due to a small flaw in "trace_tuner", the outgoing packets are not currently dumped.. that will get fixed in the next release. I have added code to dump them on my own player, and the "in=01000303" is a response to this from the player: "0100010000000000000000".

Cheers.
