OK, so here's another "weird" thang. The headphone jack on the SL6000 is a 2.5mm, not a 3.55mm which is the internationally recognized freakin' standard. I guess you could pound it in with a ball peen hammer, which I'm tempted to do, but there is an adapter available. Apparently the Treo 600 uses the same f****d up size, so here's a link to the stupid thing. Aaaarrrggghhhh !

I'm now on my second, not quite so broken 6000 as my original newish one, and I have the same problem.... when I plug in the 2.5->3.5mm adaptor and my headphones I only get mono sound, and when I "dmesg | tail" it says
wm9712_update_jack_state: HP jack state changed (Jack=1,Mic=1)

when I unplug I get
wm9712_update_jack_state: HP jack state changed (Jack=0,Mic=0)

I have tried shorting out the headphone jack on either channel and watching the logs but don't see anything.

I have tried just plugging in the adaptor without the headphones too.

I can't believe two zauruses have the same fault!

Is the headphone circuitry detecting a very specific resistance?

I really really want to be able to use my Z as an in-car mp3 player with external USB hard drive, so stereo sound is vital!
