Startup Chime and volume

HI,

Open System Preferences/Sound and use thes slider at the bottom of the pane to adjust the volume.

You can also do this in your iMac keyboard. F10 F11 and F12

Just to point one thing out... that startup chime means your Mac has passed it's diagnostics test. It's important that you hear it when you start up your Mac.

Ok.. try resetting the PRAM/NVRAM, instructions here.

Restore PRAM and NVRAM to Defaults :
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
7. Your computer’s PRAM and the NVRAM are reset to the default values.

It corrects ...

HI,

*"Which basically means their is no solution to my problem."*

Not in my book 😉

Are you using external speakers? If not...

Boot from another user account. Shut dow the iMac, then restart. See if the problem persists.

If it does, then the problem is system wide, if it doesn't, then the problem is isolated to your admin account only.

If this occurs just in your account, try deleting this file.

com.apple.Components2.LocalCache.AudioComponents

It's here: ~/Library/Caches.

Drag that file to the Trash, empty the Trash and restart your iMac.

Hi CellaMarr

I hope this fix below helps you, it did for me!

Click on this link, http://discussions.apple.com/thread.jspa?messageID=10097003&#10097003, which is another post in the Apple Discussions, it has a fix for your Mac.

As a safety measure I did not delete the files straight away, I moved them to the trash ready to use the 'put back' facility if the problem was not fixed.

Let me know how you get on.
