"I went to the Audio MIDI Setup control and found that the default and system outputs are listed as built-in audio but under Audio Output it says that output is not supported (not sure if this is relevant or not)."
Did you make sure all the Audio settings were correct? See Knowledge Base Article: KB article - No sound from some applications, but system alert sounds play (Mac OS X 10.3, 10.4)
Another trick: If you have GarageBand installed, open it (maybe open a GarageBand document) and then quit out of the application.
Try repairing permissions & restarting.
If the above does not work, then see Knowledge Base Article: http://docs.info.apple.com/article.html?artnum=301733 iMac G5: How to Reset the SMU (iMac G5, the iMac G5 (Ambient Light Sensor), and the iMac G5 (iSight)).
I recently had the same problem.
Computer was working fine for many years and all of a sudden many small problems have occurred including the internal speakers disappearing from the computer. Have no idea what could have caused it but I have openned Garage Band numerous times and get a "CoreAudio: Selected Driver not found (-10202)" message. Have also attached earphones and nothing seems to work. It has alos made it where my iTunes will not play at all. Try and press play and it just sits there.
In addition to no sound, my computer has become very slow and on occation will completely lock up with the beach ball of death sitting there for hours. It will also not start up at times and but as of the last couple of weeks it has been working well (a little slow) but still no audio. All software has been updated. I probably need to take this in to a service provider but was hoping someone on here would have a clue or two.

Suggest that you cross-post the above issue in one of the GarageBand Forums where the GB users hang out.
Regarding your other issues, other than the GB tip, have you tried the other suggestions in this thread? If so, suggest that you boot from your System Install Tiger DVD & run the repair disk/permissions options for starters.
Make sure all devices except for the keyboard & mouse are disconnected from your computer when troubleshooting.
You should also start a New Topic regarding your 2nd paragraph (comp slowness) as it does not pertain to this posting topic. This way, it will get more focused attention.
i have just experienced the exact same symptoms with my imac.
i had the main logic board replaced 2 years ago after experiencing random shutdowns and then noticing leaking capacitors.
I had the same symptoms again last week, so I took it to an Apple shop and had the logic board and PSU replaced.
I brought it home on Saturday and now I have the same problem as you.
The headphone socket works, but you cannot control the volume, there is a 'no entry' sign under the volume overlay, and the speakers don't work.
I have taken it back to the store and am awaiting a call today.
At first the techs thought it might be a loose cable; then they suspected that the logic board fitted is faulty.
As you can imagine I am very annoyed!

"how much does a Logic main board cost???"
That would depend on the model of your G5 iMac, where you purchase the logic board from & of course taxes.

Perhaps it would be easier if you describe in detail your problem(s). Depending on the problem your computer just may qualify for the G5 iMac Repair Programs
**WARNING: DUE TO SECURITY REASONS, PLEASE DO NOT POST YOUR COMPUTER'S SERIAL NUMBER ON THESE MESSAGE BOARDS.**
Which "model" & "generation" G5 iMac do you have?
Need this info so that the knowledgeable users can provide you with the proper troubleshooting solution(s).

You can have this info displayed on the bottom of every post by going to 'My Settings' which is located in the column on the right under your name, and filling in the information asked for.
Upon having my logic board and power supply replaced for leaky capacitors, I had no speaker output. It was a faulty replacement board which was replaced. By-the-way the cost of a logic board as of 18 Nov 2005, was $731.81. If I had one go bad now and I was out of warranty, I would just purchase a new iMAC.
I purchase an iMac for my wife for Christmas. The internal speakers stopped working within the first 2 hours of using the device. After trying all the recommended software configuration and plug in headphones - unplug headphones resolutions I took it in to an Apple service shop.
They have reported back that the "logic board" needs to be replaced. Two hours of use and 10 days in the repair shop. Not a distinguished start.
However, given the prevalence of reports that 'internal speakers' stopped working, I'm sceptical that the problem is actually a hardware problem and that the problem won't recur with the new logic board.
