My speakers are permanently muted as if there were headphones plugged into the right front speaker headphone jack. I can hear music from the headphones when they are plugged in, but audio does not return to the speakers when I unplug the headphones. I've had this problem intermittently and the audio usually came back on if I waited a few minutes, but that is no longer the case. Powering the speakers off and on does not help.

I just encountered the same problem with my 506, so, in the interest of helping others who encounter this problem in the future:
It seems to be that the control speaker isn't recognizing that the headphones are no longer plugged in. While not a fix, per se, I have found a workaround:
- Turn on a constant sound to go through your speakers (such as music or white noise).
- Plug your headphones into the control speaker.
- Remove the headphone plug, but not all the way. Leave it about halfway in.
- Apply a small (very small!) amount of pressure to the headphone plug in a perpendicular direction.
- Rotate the direction you apply the pressure until the external speakers kick on.
[Simple explanation]: Put the plug in halfway and wiggle it until you get sound.
This is clearly a hardware issue with the headphone jack. My suspicion is that there is a switch in the headphone jack that is engaged when headphones are plugged in, routing the power tot he headphones instead of the speakers. Thus, the problem likely arises from this switch sticking, particularly if the headphones have been plugged in for an appreciable amount of time.
If your speakers are under warranty still, I recommend following Logicool's advice and contacting Logitech about a replacement or repair. It's likely that this problem will only get worse.

The headphone jack may have a switch on it. Activated by inserting and removing the headphone connector.
It could be going bad.
I know my Z2300s actually have a switch on its headphone jack that sends a signal to the electronics to turn Off the speaker amps and only route audio the headphones.
