Startup Chime but then no sound

Question

Startup Chime but then no sound

I have two pre-iSight iMac G5s, one is a 1.8 and the other a 2.0. I just had to wipe them clean to give them to a new user, and installed 10.3.9. My issue is now everything seems to work fine except there is no sound after booting up. Going into the sound control panel shows no output device available. I tried resetting the SMU, PRAM, re-running the OS X 10.3.9 combo update.

I don't have any external speakers attached, and the trying to set the bit rate in the Audio MIDI Setup didn't work, neither did the playing a loop in garage band.

Any help would be greatly appreciated. I seem to remember a problem just like this right after these machines first shipped, but I can't remember the solution. I'm hoping one of you will!!!

Did you make sure "mute" was unchecked in the System Preferences Sound control panel?

See if running fsck helps any.

Sorry, I don't know anything about Panther. Hopefully, a Panther knowledgable user will chime in here to tell you which sound preferences you can trash if any and/or in the meantime you can cross-post in the Panther Forums where the Panther users hang out.

Yes, it doesn't even show any onboard audio options, it has device not present, so it will not allow me to check or uncheck anything.

But thanks for the reply.

If you tried to change the audio output 44100.0Hz and it didn't help, it would seem that you have done just about everything that is recommended for this problem. Just for kicks, try connecting external speakers and see if you hear anything, also, try headphones and see what happens.

i have just come onto this forum to search a solution for exactly the same problem! also with a G5 imac & have tried everything - it works thru external speakers but not the internal speakers - in the system preferences > sound - the output tab shows 'digital audio' instead of 'internal speakers' & there seems no way to get back to internal speakers.

there must be a simple solution to this but i can't find it....... anyone??

Bernies, in order to help the knowledgable users will need more details about your system. Which model/generation G5 iMac do you have?

Please describe all the troubleshooting efforts have you tried. We need this info to avoid the "been there, done that" senerios.
You may have already tried the "simple solution" you're looking for if there is one! 🙂

Thank you!

Same condition, and
System Profiler Audio (Built-in) reads: "No built-in audio".
Every application, system alert, etc. is SILENT. DVD Player, QT, FCPro, Garage Band, iDVD and all other apps & utilities report unavailable audio I/O devices.

I'd been using my son's 2GHz PPC iMac G5 (Mac OS 10.4.for video editing and DVD authoring. FCP 3, iDVD, iTunes, QT Player ALL worked fine. He took the iMac home and Kernel Panics ensued. He brought it back, and I've tried every fix I could find, but now the iMac ONLY starts up in SAFE MODE.

I've tried "repair permissions" repeatedly, reset PRAM & SMU,"Archive & Install", too! Nothing solves my problems. Any suggestions?

Did you do this from your Tiger DVD? If not, I suggest that you try this & also disk repair. See if this helps.

Hi baby boomer - yeah sorry... - its a first generation 17 inch iMac G5, 1.8 mhz with osx 10.3.9

I am begining to think that this maybe a hardware issue rather than software as I have gone through the whole process of erase & re loading osx plus all of the software updates & replacing all the files & the same problem was there from the outset again

though i guess that worse things happen at sea... but it is bloody annoying!

It seemes that this has come up quite a lot on this discussion & have read quite a few threads but there seems to be no definitive answer - having tried hardware tests & reset pram too.

if anyone has a solution it would be great tho.
thanks!

Yes, I'm using Tiger DVD 10.4. I've also tried 3rd parties (Drive Genius, Hardware Toolkit) with no hardware problems found.
Only being able to start up in SAFE MODE is VERRRYY annoying!
