iMac (Early 2006 17-inch) Troubleshooting — Symptom Charts 159
I hear sound out of only one speaker.
Are there any external microphones, speakers or headphones plugged into the iMac?
Yes: Disconnect any external microphones, speakers, or headphones. Do you hear audio from
both of the built in speakers on your iMac?
Yes: Good. It looks like the built-in speakers are working properly. This may be an issue
with the microphone, speakers or headphones that were plugged into your iMac. Please
work with the manufacturer to troubleshoot this issue.
No: Go to step 2.
No: Check your speaker balance. If your balance setting was set to the left or right speaker,
you would only hear sound from one speaker. Go to step 2.
Open System Preferences. (System Preferences can be found under the Apple menu.)
Click once on the sound icon.
Click once on the Output tab.
Make sure your balance setting is in the middle. After adjusting the audio balance, do you
have audio from both speakers now?
Yes: It looks like the issue was the balance was not set properly.
No: Replace the speakers.
If the speakers did not solve the problem, replace the logic board.
