This is the second time an update has done this to me (Early 2008 Mac Pro).

Run the update - reboot - "sound effects" and "output" changed from "line out" to "internal speakers".

What's up with that? Not a big deal - but kind of a pita when I get a call at work from a family member asking why iTunes is playing from the internal speaker...

For me it's temporary - only happens after some (2 so far) OS point updates complete. Once I go into the audio settings and set the outputs back to line out - no more problems after that.

This happened to me too. However, I cannot get my iChat sounds to come out my line out no matter what I try. All other sounds come out my line out except for iChat. Anyone else have this problem? It's driving me nuts!

If you're having trouble with Sound Effects or iChat, check this out.

In the sound preferences of system preferences, under sound effects, where does it say "play sound effects through?" If it says internal speakers, then it will always play through there even if your output is selected as line out or USB speakers.
I found this in another thread and I thought I'd share. Thank you Southerndoc!

Even when i switch the output, half the sounds come through the internal speakers still.

Check what source your sound effects are set to. See the post directly above yours. You can't just change the output, you also have to change the sound effects output too.

I have an early 2007 Mac Pro and have this same issue even after restarting a couple of times (sound always reverts to internal speakers from digital out).

Seems to me that preferences of the sound control panel are being played around with or something changes them on start-up.

I had the same problem too. Took me a little while to figure out which settings to change back. But it's all good now.

Still a little irritating that they keep doing this. As has been mentioned it's not the first time.

I have an issue where the only sound that works is the internal speaker. I have external speakers hooked up via line out but if I switch to them, I still don't hear anything...

Yup, after the 10.6.2 update the sound on my MP was changed to "Display Audio". Had to go to the sound preferences and change it back to "Line Out". Oh well--all is well now.

Today I also found out that if you log out and log back in, the same problem occurs, sound is reverted to internal speakers...

So this is not related to restarting at all... (or booting/rebooting)

I noticed this too.

After updating to 10.6.2 the internal speaker got un-muted on my Mac Pro 1.1.

However, my particular machine does have a fussy rear audio jack sensing switch that makes having sound in Windows under Boot Camp kinda tricky.

In Mac OS, you can mute the internal speaker and the sound gets directed to the rear jack (even if no speaker plug is detected) and all is good.

In Windows (under Boot Camp) if no speaker plug is detected, you get no sound at all from the rear output regardless of what you do with the internal speaker.

In Windows, the only solution for my machine is to move the speaker plug to one side and that gets the speakers going. (see drawing)

I'm curious to see if anyone else has this particular issue.

Have Fun,
Keri

I found a fix from the Apple Support forums. I had to do two steps:

1. Deleted the files on: /Library/Preferences/Audio
2. Zapped the parameter RAM (PRAM)

After this, my MacPro reverted to original settings and no longer exhibits that behavior.

Worth giving it a try!

Didn't work for me. I also removed /Library/Preferences/com.apple.soundpref to no avail. Pretty lame bug.

My bug is that when you wake from sleep the sound controls on the keyboard/thing at the top with sound makes the pop come from the internal speaker and only adjusts THAT sound.

Means i have to go into Sound preferences and select the speakers before everything reverts.

Annoying or what!

I have tried all these options to no avail. I have even spoken to mApple and they seem to have no idea this problem even exists!

what support forum and what thread?

Anybody have anything?

Thanks for your help in advance

Here is a good solution found on apple discussion forum!

I finally found the root cause of my problems for this. The problem for me is with file permissions on the 2 Audio plist files. For some reason during the 10.5.6 upgrade they are not set properly. Looking at the all the answers on the forum that seemed worked for one reason or another confirm they are related to file permissions.

I also have a permanent, reasonably easy fix for it. To fix the permission problem, you need to change the ownership of the files as described below.

========================
Launch Terminal from Utilities folder. This automatically logs you in as yourself.

To change file ownership, your need to switch login as root. Follow the commands in bold. I left the detailed listing so you can see what to expect. You can copy and paste the bold text into Terminal as they are to save retyping.

Note the ownership change from "jdoe" to "_coreaudiod"

unix$ sudo -i
password: type your normal user password here

unix# cd /Library/Preferences/Audio
unix# ls -l
-rw-r--r-- 1 jdoe admin 3149 11 Nov 22:17 com.apple.audio.DeviceSettings.plist
-rw-r--r-- 1 jdoe admin 1363 11 Nov 13:06 com.apple.audio.SystemSettings.plist

unix# chown _coreaudiod com.apple.audio.DeviceSettings.plist

unix# chown _coreaudiod com.apple.audio.SystemSettings.plist

unix# ls -l
-rw-r--r-- 1 _coreaudiod admin 3149 11 Nov 22:17 com.apple.audio.DeviceSettings.plist
-rw-r--r-- 1 _coreaudiod admin 1363 11 Nov 13:06 com.apple.audio.SystemSettings.plist

unix# exit

quit Terminal
=============================================
all the commands without the surrounding text for easy copy & paste

sudo -i
cd /Library/Preferences/Audio
ls -l
chown _coreaudiod com.apple.audio.DeviceSettings.plist
chown _coreaudiod com.apple.audio.SystemSettings.plist
ls -l
exit
=============================================

change your Sound Output setting
see if the timestamp changes on: com.apple.audio.SystemSettings.plist
the other plist will change after restart
restart your Mac and see if it works

good luck!

If this fails for some reason, I have another way of changing the setting that works but is not preferred. You can edit the plist directly to change the Sound Output but it is harder to do and does not sync with System Preference changes.

Try it!
