fried sound card - repair or add external?
After a nearbly lightning strike, my stereo receiver and iMac's sound card both seem to be toast. They were connected via a RCA cable > 1/8" plug to the Mac's headphone jack. Now, System Prefs >Sound shows "no output devices found", and About This Mac > System Report > Audio shows nothing.
I've run through the recommended fixes, and Diagnostic restart shows no error.
Is it worth my trying to have this repaired, or should I simply buy an external sound card/DAC? My insurance sounds like it will likely cover either option, though I'd rather not go to my nearest Apple Store (1 hr. drive) and have to leave the computer for who knows how long....
Thanks!
