Based on similar comments by others about the Bose 321 system on this web site, this appears to be a significant and relatively frequent problem...maybe even a design flaw

I concur, the cable jacks want to fall out - but I just bought a better set from Radio Shack and cured that problem

All in all I would definately reccomend this to anyone with space limitations as well as constructual problems that might limit the possibilities for your home theater system.

We've tried everything to remedy this problem, including pushing the unit up against the back wall of our entertainment center in order to keep the plugs from falling out.

The only way to clear the problem is to restart the system.

I would like Bose to replace it, but after reading the pervasive problems online, I think it's better just not to buy this system at all
