External speakers and earphones do not work but imac speakers do

[gkallis]

Hi there,

the external speakers (and the earphones) I use for my i-mac suddenly stopped playing sound from my imac. They do work though when I plug them to the i-pod. My imac speakers work perfectly. Any ideas what's happening?

Thanks.

Check your sound output settings from System Preferences -> Sound -> Sound output
