For the fact that I have already lost my first adapter from Radio Shack I am looking at get headphones like the JAVOebuds.

Anyone else find any other headphones that already have the 2.5mm plug so I do nto have to carry an adapter?

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
CODE
wm9712_update_jack_state: HP jack state changed (Jack=1,Mic=1)

when I unplug I get
CODE
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!

My Javo ebuds have stereo sound with true stereo separation, not just mono playing on both sides. Maybe the problem is with the adapter?

EDIT: by the way, glad you got a working 6000 back. smile.gif
