Replace audio port?

[titaniumdecoy]

I have plugged headphones into the standard audio out port on my MacBook Pro for the last few years, but recently when the cord is jiggled or pulled slightly the volume drops or rises and it causes EyeTV to quit. Aside from having the port replaced, is there an external USB or ExpressCard option to get another audio out port?

I found a sampling of USB speakers:

There's also this little toy for Firewire, although I haven't tried it:

Also, have you checked to see if the optical source in your computer is still okay?
