All of a sudden my built in sound quit. In prefs it says there are no outputs available although built in is acknoledged in DP.

Tried plugging and unplugging mini port in front of machine several times and nothing...

Never see this before ever.

I've had this happen lots more with earlier versions of OSX, but from time to time it still happens.

First quite DP, then check System Prefs> Sound and for the moment route all of your audio to your interface *temporarily*.

Then go to Audio-MIDI and whether or not your desired routings appear to be done properly, deselect them and then reselect them. Leave Audio-MIDI open for now.

If you have a separate console for your audio card/interface, open it and refresh any audio connections there as well.

Start DP, and check to see if things are behaving properly. Check your Bundles. If there is a Built-In setting there remove it and put in a fresh one. If there is not one there, make a new one.

If not, quit all apps and utilities, repair permissions, shut down, and reboot.

Check to see if System Prefs/Sound, Audio-MIDI, and your interface console-control panel are still set properly.

Start DP.

If things are still not right, Trash System Prefs and reboot DP.

Wash, rinse, repeat.

T-- that's a real bummer, that is.

Try to go through every silly little setting or connector you can think of. It just might be one of those "duh" something-or-others. (You've probably already done this, but it's always the one you miss in the heat of the moment...) Topping this list is the audio mute button next to the eject button on the number pad.

Given that your System Prefs>Sound and your Audio-MIDI settings appear to be fine-- and the audio mute button (or some other silly thingy) was not the solution--

...and if repair permissions or if DiskWarrior or some other utility didn't do it, and you've come to the bottom of the troubleshooting barrel....

...try to "archive and install" OSX. That will save everything else on your HD while making a new version of OSX. You may have to start with an OSX disc, then download the latest version.

Make sure Audio/MIDI setup shows a sampling rate of 44.1 khz for built in audio.

It's a mechanical failure.

I tried a 30 minute reset as perscribed by Apple discuss forum by pulling all plugs and A/c and that didn't work either.

I have Apple care though.

Thanks for the help.

Grrreat news!

Tried the reset one more time for an hour and it worked last night.

I was told you can discover the errorrs or shorts in system profiler. Not sure about this though.

Sometimes I've found RAM count errors and at other times I've found certain HDs not mounted in SP. Not sure about it doing much else than telling you what's loaded and not showing what isn't loaded that should be.. hmmm.

See-- that's another one of those REALLY stubborn UNIX thingies remedied only by the super secret comatose reset process.

Glad to know you're back in stride, T.

Yea it could have been mechanical. I installed a new -rw MCE dvd drive and wires or plugs to the speaker might have been the culprit. The speaker is dead still. the plugs work however so at least I can plug it to the API seletor. .Possibly a shorted speaker caused it, Still have to find out what's up here. MAybe next year.

Best of the Holidays
